|
|
Run HTTPie and capture stderr/out and exit status.
|
|
Content writtent to devnull will be captured only if
|
|
env.devnull is set manually.
|
|
|
|
Invoke `httpie.core.main()` with `args` and `kwargs`,
|
|
and return a `CLIResponse` subclass instance.
|
|
|
|
The return value is either a `StrCLIResponse`, or `BytesCLIResponse`
|
|
if unable to decode the output. Devnull is string when possible,
|
|
bytes otherwise.
|
|
|
|
The response has the following attributes:
|
|
|
|
`stdout` is represented by the instance itself (print r)
|
|
`stderr`: text written to stderr
|
|
`devnull` text written to devnull.
|
|
`exit_status`: the exit status
|
|
`json`: decoded JSON (if possible) or `None`
|
|
|
|
Exceptions are propagated.
|
|
|
|
If you pass ``tolerate_error_exit_status=True``, then error exit statuses
|
|
won't result into an exception.
|
|
|
|
Example:
|
|
|
|
$ http --auth=user:password GET httpbin.org/basic-auth/user/password
