Nodejs-Request Promise从POST获取JSON响应主体

Question

I'm trying to make a POST request using request-promise to an HTTP service which returns back JSON data. I'm using resolveWithFullResponse set to true and have the json option set to true. I'm also using the gzip option if that makes a difference.

Is there anyway I can have request-promise automatically convert the response data to JSON? Currently, the response body is a string. Here is what my request options look like:

{
   url: 'http://foo.com/getData',
   json: true,
   body: {
      hello: world
   },
   resolveWithFullResponse: true,
   gzip: true
}

Answer 1

You should use transform option of the request module. Find below the request object.

{
   url: 'http://foo.com/getData',
   json: true,
   body: {
      hello: world
   },
   resolveWithFullResponse: true,
   gzip: true,
   transform: function (body, response) {
                if (response.headers['content-type'] === 'application/json') {
                    response.body = JSON.parse(body);
                }
                return response;
            }
}
