Guzzlehttp - How get the body of a response from Guzzle 6

Question

I m trying to write a wrapper around an api my company is developing   It s restful  and using Postman I can send a post request to an endpoint like http   subdomain dev myapi com api v1 auth  with a username and password as POST data and I am given back a token   All works as expected   Now  when I try and do the same from PHP I get back a GuzzleHttp Psr7 Response object  but can t seem to find the token anywhere inside it as I did with the Postman request     The relevant code looks like     client   new Client   base uri    gt   http   companysub dev myapi com       response    client- gt post  api v1 auth           form params    gt             username    gt   user           password    gt   password            var dump  response     or  resonse- gt getBody    etc      The output of the code above looks something like  warning  incoming wall of text    object guzzlehttp psr7 response  36  6        reasonphrase   guzzlehttp psr7 response  private   gt    string 2   ok      statuscode   guzzlehttp psr7 response  private   gt    int 200      headers   guzzlehttp psr7 response  private   gt    array 9          connection    gt      array 1           0   gt        string 10   keep-alive              server    gt      array 1           0   gt        string 15   gunicorn 19 3 0              date    gt      array 1           0   gt        string 29   sat  30 may 2015 17 22 41 gmt              transfer-encoding    gt      array 1           0   gt        string 7   chunked              content-type    gt      array 1           0   gt        string 16   application json              allow    gt      array 1           0   gt        string 13   post  options              x-frame-options    gt      array 1           0   gt        string 10   sameorigin              vary    gt      array 1           0   gt        string 12   cookie  host              via    gt      array 1           0   gt        string 9   1 1 vegur                headerlines   guzzlehttp psr7 response  private   gt    array 9          connection    gt      array 1           0   gt        string 10   keep-alive              server    gt      array 1           0   gt        string 15   gunicorn 19 3 0              date    gt      array 1           0   gt        string 29   sat  30 may 2015 17 22 41 gmt              transfer-encoding    gt      array 1           0   gt        string 7   chunked              content-type    gt      array 1           0   gt        string 16   application json              allow    gt      array 1           0   gt        string 13   post  options              x-frame-options    gt      array 1           0   gt        string 10   sameorigin              vary    gt      array 1           0   gt        string 12   cookie  host              via    gt      array 1           0   gt        string 9   1 1 vegur                protocol   guzzlehttp psr7 response  private   gt    string 3   1 1      stream   guzzlehttp psr7 response  private   gt    object guzzlehttp psr7 stream  27  7          stream   guzzlehttp psr7 stream  private   gt      resource 40  of type  stream        size   guzzlehttp psr7 stream  private   gt      null       seekable   guzzlehttp psr7 stream  private   gt      bool true        readable   guzzlehttp psr7 stream  private   gt      bool true        writable   guzzlehttp psr7 stream  private   gt      bool true        uri   guzzlehttp psr7 stream  private   gt      string 10   php   temp        custommetadata   guzzlehttp psr7 stream  private   gt      array 0                  The output from Postman was something like          data               token   fasdfasf-asfasdfasdf-sfasfasf            Clearly I m missing something about working with the response objects in Guzzle   The Guzzle response indicates a 200 status code on the request  so I m not sure exactly what I need to do to retrieve the returned data

If expecting JSON back  the simplest way to get it    data   json decode  response- gt getBody        returns an object     OR   data   json decode  response- gt getBody    true      returns an array   json decode   will automatically cast the body to string  so there is no need to call getContents

Guzzle implements PSR-7  That means that it will by default store the body of a message in a Stream that uses PHP temp streams  To retrieve all the data  you can use casting operator    contents    string   response- gt getBody      You can also do it with   contents    response- gt getBody  - gt getContents      The difference between the two approaches is that getContents returns the remaining contents  so that a second call returns nothing unless you seek the position of the stream with rewind or seek     stream    response- gt getBody     contents    stream- gt getContents       returns all the contents  contents    stream- gt getContents       empty string  stream- gt rewind       Seek to the beginning  contents    stream- gt getContents       returns all the contents   Instead  usings PHP s string casting operations  it will reads all the data from the stream from the beginning until the end is reached    contents    string   response- gt getBody       returns all the contents  contents    string   response- gt getBody       returns all the contents   Documentation  http   docs guzzlephp org en latest psr7 html responses
