req is a very simple command line wrapper around Mikeal Roger's excellent request library.

req tries to make some guesses as to what you'd really like to do. When a body is detected as parseable json, req will send it with the appropriate content-type. When sending a file, req will base the Content-Type on the file's extension. On a GET request, req will print text and json to stdout, while other requests will be saved to a file according to either a Content-Disposition filename or the path of the request. You can override this, of course, by using the -o flag (works for text and json as well). Any headers that you manually specify will always take precedence over req's guesses.

I wrote this little wrapper because I got tired of curl's massive man-page and unintuitive flags. Is it as powerful as curl? Probably not, but it is definitely easier to use.

Usage:

Usage: req [options] [method] uri

Methods:
  Any valid HTTP method is supported. If unspecified, GET will be used.

Options:
  -h, --headers      Headers to attach to the request in the form header=value                                                                                                                  
  -q, --querystring  Querystring parameters in the form param=value (these can also be passed as part of the URI)                                                                               
  -b, --body         The body of the request. If this is set to valid json, it will automatically set the json content-type. Can also attach the contents of the file using e.g. @uploadthis.txt
  -o, --output       File to write output to, otherwise will print text and json to screen and guess a filename for binaries                                                                    
  -u, --username     Username for basic auth                                                                                                                                                    
  -p, --password     Password for basic auth                                                                                                                                                    
  -f, --form         Similar to the body flag, but sends the data as x-www-form-urlencoded                                                                                                       
  -v, --verbose      Output response headers and status codes   

Some examples:

To upload the file picture.jpg to example.com (assumes a POST request, automatically sets Content-Type to image/jpeg based on file extension)

req -b @picture.jpg example.com/pictures

To PUT some plain text as form data (x-www-form-urlencoded)

req put -f 'formdata' example.com/forms

To POST a JSON blob to example.com/users?user=tom (automatically detects valid json and sets Content-Type to application/json)

req -b '{"status": "bored"}' -q user=tom example.com/users

Setting multiple query strings or headers is as easy as adding more -q or -h flags (PUT example.com/users?user=tom&status=bored&location=home)

req put -q user=tom -q status=bored -q location=home example.com/users

Basic auth? Not a problem! (Note that currently you must specify these inline. A prompt will be coming in the next version)

req -u username -p password secureexample.com
