||||
### Password protecting your web service
|
||||
|
||||
Anyone who can guess your tunnel URL can access your local web server unless you protect it with a password.
|
||||
|
||||
This enforces HTTP Basic Auth on all requests with the username and password you specify in frpc's configure file.
|
||||
|
||||
It can be only enabled when proxy type is http.
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[web]
|
||||
privilege_mode = true
|
||||
type = http
|
||||
local_port = 80
|
||||
custom_domains = test.yourdomain.com
|
||||
http_user = abc
|
||||
http_pwd = abc
|
||||
```
|
||||
|
||||
Visit `test.yourdomain.com` and now you need to input username and password.
|
||||
|
||||
### Custom subdomain names
|
||||
|
||||
It is convenient to use `subdomain` configure for http、https type when many people use one frps server together.
|
||||
|
||||
```ini
|
||||
# frps.ini
|
||||
subdomain_host = frps.com
|
||||
```
|
||||
|
||||
Resolve `*.frps.com` to the frps server's IP.
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[web]
|
||||
privilege_mode = true
|
||||
type = http
|
||||
local_port = 80
|
||||
subdomain = test
|
||||
```
|
||||
|
||||
Now you can visit your web service by host `test.frps.com`.
|
||||
|
||||
Note that if `subdomain_host` is not empty, `custom_domains` should not be the subdomain of `subdomain_host`.
|
||||
|
||||
### Connect frps by HTTP PROXY
|
||||
|
||||
frpc can connect frps using HTTP PROXY if you set os environment `HTTP_PROXY` or configure `http_proxy` param in frpc.ini file.
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
http_proxy = http://user:pwd@192.168.1.128:8080
|
||||
```
|
||||
|
||||
## Development Plan
|
||||
|
||||
* Support udp protocol.
|
||||
* Support wildcard domain name.
|
||||
* Url router.
|
||||
* Log http request information in frps.
|
||||
* Direct reverse proxy, like haproxy.
|
||||
* Load balance to different service in frpc.
|
||||
* Debug mode for frpc, prestent proxy status in terminal.
|
||||
* Inspect all http requests/responses that are transmitted over the tunnel.

|
||||
|
||||
### 转发 DNS 查询请求
|
||||
|
||||
DNS 查询请求通常使用 UDP 协议，frp 支持对内网 UDP 服务的穿透，配置方式和 TCP 基本一致。
|
||||
|
||||
1. 修改 frps.ini 文件，配置一个名为 dns 的反向代理：
|
||||
|
||||
```ini
|
||||
# frps.ini
|
||||
[common]
|
||||
bind_port = 7000
|
||||
|
||||
[dns]
|
||||
type = udp
|
||||
listen_port = 6000
|
||||
auth_token = 123
|
||||
```
|
||||
|
||||
2. 启动 frps：
|
||||
|
||||
`./frps -c ./frps.ini`
|
||||
|
||||
3. 修改 frpc.ini 文件，设置 frps 所在服务器的 IP 为 x.x.x.x，转发到 Google 的 DNS 查询服务器 `8.8.8.8` 的 udp 53 端口：
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
auth_token = 123
|
||||
|
||||
[dns]
|
||||
type = udp
|
||||
local_ip = 8.8.8.8
|
||||
local_port = 53
|
||||
```
|
||||
|
||||
4. 启动 frpc：
|
||||
|
||||
`./frpc -c ./frpc.ini`
|
||||
|
||||
5. 通过 dig 测试 UDP 包转发是否成功，预期会返回 `www.google.com` 域名的解析结果：
|
||||
|
||||
`dig @x.x.x.x -p 6000 www.goolge.com`

||||
需要注意的是 frpc 所在机器和 frps 所在机器的时间相差不能超过 15 分钟，因为时间戳会被用于加密验证中，防止报文被劫持后被其他人利用。
|
||||
|
||||
这个超时时间可以在配置文件中通过 `authentication_timeout` 这个参数来修改，单位为秒，默认值为 900，即 15 分钟。如果修改为 0，则 frps 将不对身份验证报文的时间戳进行超时校验。

||||

||||
### 加密与压缩

|
||||
|
||||
### 通过密码保护你的 web 服务
|
||||
|
||||
由于所有客户端共用一个 frps 的 http 服务端口，任何知道你的域名和 url 的人都能访问到你部署在内网的 web 服务，但是在某些场景下需要确保只有限定的用户才能访问。
|
||||
|
||||
frp 支持通过 HTTP Basic Auth 来保护你的 web 服务，使用户需要通过用户名和密码才能访问到你的服务。
|
||||
|
||||
该功能目前仅限于 http 类型的代理，需要在 frpc 的代理配置中添加用户名和密码的设置。
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[web]
|
||||
privilege_mode = true
|
||||
type = http
|
||||
local_port = 80
|
||||
custom_domains = test.yourdomain.com
|
||||
http_user = abc
|
||||
http_pwd = abc
|
||||
```
|
||||
|
||||
通过浏览器访问 `test.yourdomain.com`，需要输入配置的用户名和密码才能访问。
|
||||
|
||||
### 自定义二级域名
|
||||
|
||||
在多人同时使用一个 frps 时，通过自定义二级域名的方式来使用会更加方便。
|
||||
|
||||
通过在 frps 的配置文件中配置 `subdomain_host`，就可以启用该特性。之后在 frpc 的 http、https 类型的代理中可以不配置 `custom_domains`，而是配置一个 `subdomain` 参数。
|
||||
|
||||
只需要将 `*.subdomain_host` 解析到 frps 所在服务器。之后用户可以通过 `subdomain` 自行指定自己的 web 服务所需要使用的二级域名，通过 `{subdomain}.{subdomain_host}` 来访问自己的 web 服务。
|
||||
|
||||
```ini
|
||||
# frps.ini
|
||||
subdomain_host = frps.com
|
||||
```
|
||||
|
||||
将泛域名 `*.frps.com` 解析到 frps 所在服务器的 IP 地址。
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[web]
|
||||
privilege_mode = true
|
||||
type = http
|
||||
local_port = 80
|
||||
subdomain = test
|
||||
```
|
||||
|
||||
frps 和 fprc 都启动成功后，通过 `test.frps.com` 就可以访问到内网的 web 服务。
|
||||
|
||||
需要注意的是如果 frps 配置了 `subdomain_host`，则 `custom_domains` 中不能是属于 `subdomain_host` 的子域名或者泛域名。
|
||||
|
||||
同一个 http 或 https 类型的代理中 `custom_domains` 和 `subdomain` 可以同时配置。
|
||||
|
||||
### 通过 HTTP PROXY 连接 frps
|
||||
|
||||
在只能通过代理访问外网的环境内，frpc 支持通过 HTTP PROXY 和 frps 进行通信。
|
||||
|
||||
可以通过设置 `HTTP_PROXY` 系统环境变量或者通过在 frpc 的配置文件中设置 `http_proxy` 参数来使用此功能。
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
http_proxy = http://user:pwd@192.168.1.128:8080
|
||||
```
|
||||
|
||||
## 开发计划
|
||||
|
||||
计划在后续版本中加入的功能与优化，排名不分先后，如果有其他功能建议欢迎在 [issues](https://github.com/fatedier/frp/issues) 中反馈。
|
||||
|
||||
* 支持 udp 协议。
|
||||
* 支持泛域名。
|
||||
* 支持 url 路由转发。
|
||||
* frps 记录 http 请求日志。
|
||||
* frps 支持直接反向代理，类似 haproxy。
|
||||
* frpc 支持负载均衡到后端不同服务。
|
||||
* frpc debug 模式，控制台显示代理状态，类似 ngrok 启动后的界面。
|
||||
* frpc http 请求及响应信息展示。

Package spew implements a deep pretty printer for Go data structures to aid in
|
||||
debugging.
|
||||
|
||||
A quick overview of the additional features spew provides over the built-in
|
||||
printing facilities for Go data types are as follows:
|
||||
|
||||
* Pointers are dereferenced and followed
|
||||
* Circular data structures are detected and handled properly
|
||||
* Custom Stringer/error interfaces are optionally invoked, including
|
||||
on unexported types
|
||||
* Custom types which only implement the Stringer/error interfaces via
|
||||
a pointer receiver are optionally invoked when passing non-pointer
|
||||
variables
|
||||
* Byte arrays and slices are dumped like the hexdump -C command which
|
||||
includes offsets, byte values in hex, and ASCII output (only when using
|
||||
Dump style)
|
||||
|
||||
There are two different approaches spew allows for dumping Go data structures:
|
||||
|
||||
* Dump style which prints with newlines, customizable indentation,
|
||||
and additional debug information such as types and all pointer addresses
|
||||
used to indirect to the final value
|
||||
* A custom Formatter interface that integrates cleanly with the standard fmt
|
||||
package and replaces %v, %+v, %#v, and %#+v to provide inline printing
|
||||
similar to the default %v while providing the additional functionality
|
||||
outlined above and passing unsupported format verbs such as %x and %q
|
||||
along to fmt
|
||||
|
||||
Quick Start
|
||||
|
||||
This section demonstrates how to quickly get started with spew. See the
|
||||
sections below for further details on formatting and configuration options.
|
||||
|
||||
To dump a variable with full newlines, indentation, type, and pointer
|
||||
information use Dump, Fdump, or Sdump:
|
||||
spew.Dump(myVar1, myVar2, ...)
|
||||
spew.Fdump(someWriter, myVar1, myVar2, ...)
|
||||
str := spew.Sdump(myVar1, myVar2, ...)
|
||||
|
||||
Alternatively, if you would prefer to use format strings with a compacted inline
|
||||
printing style, use the convenience wrappers Printf, Fprintf, etc with
|
||||
%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
|
||||
%#+v (adds types and pointer addresses):
|
||||
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
|
||||
Configuration Options
|
||||
|
||||
Configuration of spew is handled by fields in the ConfigState type. For
|
||||
convenience, all of the top-level functions use a global state available
|
||||
via the spew.Config global.
|
||||
|
||||
It is also possible to create a ConfigState instance that provides methods
|
||||
equivalent to the top-level functions. This allows concurrent configuration
|
||||
options. See the ConfigState documentation for more details.
|
||||
|
||||
The following configuration options are available:
|
||||
* Indent
|
||||
String to use for each indentation level for Dump functions.
|
||||
It is a single space by default. A popular alternative is "\t".
|
||||
|
||||
* MaxDepth
|
||||
Maximum number of levels to descend into nested data structures.
|
||||
There is no limit by default.
|
||||
|
||||
* DisableMethods
|
||||
Disables invocation of error and Stringer interface methods.
|
||||
Method invocation is enabled by default.
|
||||
|
||||
* DisablePointerMethods
|
||||
Disables invocation of error and Stringer interface methods on types
|
||||
which only accept pointer receivers from non-pointer variables.
|
||||
Pointer method invocation is enabled by default.
|
||||
|
||||
* DisablePointerAddresses
|
||||
DisablePointerAddresses specifies whether to disable the printing of
|
||||
pointer addresses. This is useful when diffing data structures in tests.
|
||||
|
||||
* DisableCapacities
|
||||
DisableCapacities specifies whether to disable the printing of
|
||||
capacities for arrays, slices, maps and channels. This is useful when
|
||||
diffing data structures in tests.
|
||||
|
||||
* ContinueOnMethod
|
||||
Enables recursion into types after invoking error and Stringer interface
|
||||
methods. Recursion after method invocation is disabled by default.
|
||||
|
||||
* SortKeys
|
||||
Specifies map keys should be sorted before being printed. Use
|
||||
this to have a more deterministic, diffable output. Note that
|
||||
only native types (bool, int, uint, floats, uintptr and string)
|
||||
and types which implement error or Stringer interfaces are
|
||||
supported with other types sorted according to the
|
||||
reflect.Value.String() output which guarantees display
|
||||
stability. Natural map order is used by default.
|
||||
|
||||
* SpewKeys
|
||||
Specifies that, as a last resort attempt, map keys should be
|
||||
spewed to strings and sorted by those strings. This is only
|
||||
considered if SortKeys is true.
|
||||
|
||||
Dump Usage
|
||||
|
||||
Simply call spew.Dump with a list of variables you want to dump:
|
||||
|
||||
spew.Dump(myVar1, myVar2, ...)
|
||||
|
||||
You may also call spew.Fdump if you would prefer to output to an arbitrary
|
||||
io.Writer. For example, to dump to standard error:
|
||||
|
||||
spew.Fdump(os.Stderr, myVar1, myVar2, ...)
|
||||
|
||||
A third option is to call spew.Sdump to get the formatted output as a string:
|
||||
|
||||
str := spew.Sdump(myVar1, myVar2, ...)
|
||||
|
||||
Sample Dump Output
|
||||
|
||||
See the Dump example for details on the setup of the types and variables being
|
||||
shown here.
|
||||
|
||||
(main.Foo) {
|
||||
unexportedField: (*main.Bar)(0xf84002e210)({
|
||||
flag: (main.Flag) flagTwo,
|
||||
data: (uintptr) <nil>
|
||||
}),
|
||||
ExportedField: (map[interface {}]interface {}) (len=1) {
|
||||
(string) (len=3) "one": (bool) true
|
||||
}
|
||||
}
|
||||
|
||||
Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
|
||||
command as shown.
|
||||
([]uint8) (len=32 cap=32) {
|
||||
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
|
||||
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
|
||||
00000020 31 32 |12|
|
||||
}
|
||||
|
||||
Custom Formatter
|
||||
|
||||
Spew provides a custom formatter that implements the fmt.Formatter interface
|
||||
so that it integrates cleanly with standard fmt package printing functions. The
|
||||
formatter is useful for inline printing of smaller data types similar to the
|
||||
standard %v format specifier.
|
||||
|
||||
The custom formatter only responds to the %v (most compact), %+v (adds pointer
|
||||
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
|
||||
combinations. Any other verbs such as %x and %q will be sent to the the
|
||||
standard fmt package for formatting. In addition, the custom formatter ignores
|
||||
the width and precision arguments (however they will still work on the format
|
||||
specifiers not handled by the custom formatter).
|
||||
|
||||
Custom Formatter Usage
|
||||
|
||||
The simplest way to make use of the spew custom formatter is to call one of the
|
||||
convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
|
||||
functions have syntax you are most likely already familiar with:
|
||||
|
||||
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
spew.Println(myVar, myVar2)
|
||||
spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
|
||||
See the Index for the full list convenience functions.
|
||||
|
||||
Sample Formatter Output
|
||||
|
||||
Double pointer to a uint8:
|
||||
%v: <**>5
|
||||
%+v: <**>(0xf8400420d0->0xf8400420c8)5
|
||||
%#v: (**uint8)5
|
||||
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
|
||||
|
||||
Pointer to circular struct with a uint8 field and a pointer to itself:
|
||||
%v: <*>{1 <*><shown>}
|
||||
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
|
||||
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
|
||||
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
|
||||
|
||||
See the Printf example for details on the setup of variables being shown
|
||||
here.
|
||||
|
||||
Errors
|
||||
|
||||
Since it is possible for custom Stringer/error interfaces to panic, spew
|
||||
detects them and handles them internally by printing the panic information
|
||||
inline with the output. Since spew is intended to provide deep pretty printing
|
||||
capabilities on structures, it intentionally does not return any errors.

* Pointers are dereferenced and followed

* Circular data structures are detected and handled properly

on unexported types
|

* Custom types which only implement the Stringer/error interfaces via
|
||||
a pointer receiver are optionally invoked when passing non-pointer
|
||||
variables
|
||||
* Byte arrays and slices are dumped like the hexdump -C command which
|
||||
includes offsets, byte values in hex, and ASCII output
|
||||
|
||||
The configuration options are controlled by an exported package global,
|
||||
spew.Config. See ConfigState for options documentation.
|

|

See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
|
||||
get the formatted result as a string.

printing functions. The formatter is useful for inline printing of smaller data
|

types similar to the standard %v format specifier.

The custom formatter only responds to the %v (most compact), %+v (adds pointer

addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
|
||||
combinations. Any other verbs such as %x and %q will be sent to the the

standard fmt package for formatting. In addition, the custom formatter ignores
|

the width and precision arguments (however they will still work on the format
|
||||
specifiers not handled by the custom formatter).

Typically this function shouldn't be called directly. It is much easier to make

use of the custom formatter by calling one of the convenience functions such as

Printf, Println, or Fprintf.

// SequenceMatcher compares sequence of strings. The basic

// published in the late 1980's by Ratcliff and Obershelp under the
|
||||
// hyperbolic name "gestalt pattern matching". The basic idea is to find
|
||||
// the longest contiguous matching subsequence that contains no "junk"
|
||||
// elements (R-O doesn't address junk). The same idea is then applied
|
||||
// recursively to the pieces of the sequences to the left and to the right
|
||||
// of the matching subsequence. This does not yield minimal edit
|
||||
// sequences, but does tend to yield matches that "look right" to people.
|
||||
//
|
||||
// SequenceMatcher tries to compute a "human-friendly diff" between two
|
||||
// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
|
||||
// longest *contiguous* & junk-free matching subsequence. That's what
|
||||
// catches peoples' eyes. The Windows(tm) windiff has another interesting
|
||||
// notion, pairing up elements that appear uniquely in each sequence.
|
||||
// That, and the method here, appear to yield more intuitive difference
|
||||
// reports than does diff. This method appears to be the least vulnerable
|
||||
// to synching up on blocks of "junk lines", though (like blank lines in
|
||||
// ordinary text files, or maybe "<P>" lines in HTML files). That may be
|
||||
// because this is the only method of the 3 that has a *concept* of
|
||||
// "junk" <wink>.
|
||||
//
|
||||
// Timing: Basic R-O is cubic time worst case and quadratic time expected
|
||||
// case. SequenceMatcher is quadratic time for the worst case and has

// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
|
||||
//
|
||||
// Example Usage
|
||||
//
|
||||
// The following is a complete example using assert in a standard test function:
|
||||
// import (
|
||||
// "testing"
|
||||
// "github.com/stretchr/testify/assert"
|
||||
// )
|
||||
//
|
||||
// func TestSomething(t *testing.T) {
|
||||
//
|
||||
// var a string = "Hello"
|
||||
// var b string = "Hello"
|
||||
//
|
||||
// assert.Equal(t, a, b, "The two words should be the same.")
|
||||
//
|
||||
// }
|
||||
//
|
||||
// if you assert many times, use the format below:
|
||||
//
|
||||
// import (
|
||||
// "testing"
|
||||
// "github.com/stretchr/testify/assert"
|
||||
// )
|
||||
//
|
||||
// func TestSomething(t *testing.T) {
|
||||
// assert := assert.New(t)
|
||||
//
|
||||
// var a string = "Hello"
|
||||
// var b string = "Hello"
|
||||
//
|
||||
// assert.Equal(a, b, "The two words should be the same.")
|
||||
// }
|
||||
//
|
||||
// Assertions
|
||||
//
|
||||
// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
|
||||
// All assertion functions take, as the first argument, the `*testing.T` object provided by the
|
||||
// testing framework. This allows the assertion funcs to write the failings and other details to
|
||||
// the correct place.
|
||||
//
|
||||
// Every assertion function also takes an optional string message as the final argument,
|
||||
// allowing custom error messages to be appended to the message the assertion method outputs.
