PhantomJS 将发布数据发送到 RESTful API 并操作 JSON

Question

使用 PhantomJS 2.1.1 我想对用户进行身份验证并获取受保护数据的列表；到目前为止，我的这种方法没有成功。这里的任何人都可以看看并指出我正确的方向。谢谢。 我想做的是从后端获取 JSON 并在此处使用 Phantom 对其进行测试，作为我构建过程的一部分。

use strict
var AUTH_ENDPOINT = 'http://192.168.1.251';
var SERV_ENDPOINT = 'http://192.168.1.250';
var returnedData = '';

var page = require('webpage').create(),
    server = AUTH_ENDPOINT + '/services/users/login',
    settings = {
        operation: "POST",
        headers: {
           "Content-Type": "application/json"
        },
        data: JSON.stringify({'user':'myusername', 'pword':'123456789'})
    };

page.onResourceRequested = function(requestData, networkRequest) {
    console.log('Request (#' + requestData.id + '): ');
    console.log(JSON.stringify(requestData));
};

page.onResourceReceived = function(response) {
    console.log('Response (#' + response.id + ', stage "' + response.stage + '"): ' + JSON.stringify(response));
};

page.onLoadFinished = function(status) {
  console.log('Status: ' + status);
  // Do other things here...
};
page.onResourceError = function(resourceError) {
  console.log('Unable to load resource (#' + resourceError.id + 'URL:' + resourceError.url + ')');
  console.log('Error code: ' + resourceError.errorCode + '. Description: ' + resourceError.errorString);
};

page.open(server, settings, function(status) {
  console.log('Status: ' + status);
  // when successful the response from server is a JSON
  // like so '{"authtoken":"23423","user":"myname"}'
  returnedData = JSON.parse(page.plainText);
  // this should be my token
  console.log(returnedData.authtoken);
});

// now use this token on this url
var server = SERV_ENDPOINT + '/services/get/list?data=cars';
var settings = {
    operation: "GET",
    encoding: "utf8",
    headers: {
       "token": returnedData.authtoken
    }
};

page.open(server, settings, function(status) {
    console.log(status);
    if (status !== 'success') {
        console.log('Unable to get!');
    } else {
        var jsonSource = page.plainText;
        var resultObject = JSON.parse(jsonSource);
        // all of the user cars here!!
        console.log(resultObject);
    }
    // then finally close
    phantom.exit();
});

所以这就是我所拥有的，它不起作用输出在这里

Answer 1

一个错误可能是“page.plainTex”而不是“page.plainText”，这使代码对我有用。
