大量的php发布请求响应问题

Question

I am able to make a post request with guzzle php using the following code

$request = $this->request('POST', $this->url, array('form_params' => $params));

Everything works fine. But when I call

$request->getBody()->getContents();

A string "root" is attached to the beginning of the content returned.

I dont seems to understand why this is happening.

Any assistance will be appreciated.

An example of what I get when I var_dump is this

string(4) "root" 
{"access_token":"kjVbpzmk3VAWTHn3jyeaM1nal1zkFIPZrI8khmKQ",
"token_type":"Bearer",
"expires_in":604800,
"user_id":3,
"user":{
  "id":3,
  "name":"Thomas Paul"
 }
}

Meanwhile in postman I get this

{
 "access_token": "y9Jeovb3EERC4oE13yCS8WfFi3XK1eul4D4luwX3",
 "token_type": "Bearer",
 "expires_in": 604800,
 "user_id": 3,
 "user": {
   "id": 3,
   "name": "Thomas Paul"
 }
}

This is a security measure as there is a known security vulnerability in some browsers.

Also the JSON API specs require this top level element .

Guzzle is a really robust library. Maybe Postman isn't or maybe Postman removes the root element by itself... I don't know this.

I solved the problem using a

substr($request->getBody()->getContents(), 17) 

of the response and was able to remove the unwanted strings and decoded it to json
