节点 js post 内容类型表单数据得到空响应

Question

我正在尝试 post 使用节点 js 请求形成数据内容类型，但每次我收到响应时 'null'，我都可以这样做并使用post 伙计，我真的不知道代码有什么问题，这是我的来源

var req = require('request');

req.post({
   url: 'url’,
   form: {request:[{"request":"context","sequence":0,"userToken":"mytokenxyz"}]},
   headers: { 
      'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
      'Content-Type' : 'application/x-www-form-urlencoded' 
   },
   method: 'POST'
  },

  function (e, r, body) {
      console.log(body); //here the body I am getting null
  });

这是我得到正确响应的 postman 屏幕截图。我尝试了多种其他方法，但最终得到了相同的空响应。

Answer 1

it is working for me try like that 

var request = require("request");
var options = { method: 'POST',
  url: 'http://localhost:3000/admin/assignprivilege',
  headers: 
   { 'Postman-Token': 'b93555a6-46de-04f9-af2d-69ebe38ea3dd',
     'Cache-Control': 'no-cache',
     'Content-Type': 'application/json' },
  body: 
   { privilege: 
      [ { role_id: 1,
          mod_id: 1,
          p_access: 'ON',
          p_insert: 'ON',
          p_updete: 'ON',
          p_delete: 'ON',
          created_by: 1 },
        { role_id: 1,
          mod_id: 1,
          p_access: 'ON',
          p_insert: 'ON',
          p_updete: 'ON',
          p_delete: 'ON',
          created_by: 1 },
        { role_id: 1,
          mod_id: 1,
          p_access: 'ON',
          p_insert: 'ON',
          p_updete: 'ON',
          p_delete: 'ON',
          created_by: 1 },
        { role_id: 1,
          mod_id: 1,
          p_access: 'ON',
          p_insert: 'ON',
          p_updete: 'ON',
          p_delete: 'ON',
          created_by: 1 } ] },
  json: true };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

   Also try like that it can work




    "privilege":[
    {
        "role_id":1,
        "mod_id":1,
        "p_access":"ON",
        "p_insert":"ON",
        "p_updete":"ON",
        "p_delete":"ON",
        "created_by":1
    },
    {
        "role_id":1,
        "mod_id":1,
        "p_access":"ON",
        "p_insert":"ON",
        "p_updete":"ON",
        "p_delete":"ON",
        "created_by":1
    },
    {
        "role_id":1,
        "mod_id":1,
        "p_access":"ON",
        "p_insert":"ON",
        "p_updete":"ON",
        "p_delete":"ON",
        "created_by":1
    },
    {
        "role_id":1,
        "mod_id":1,
        "p_access":"ON",
        "p_insert":"ON",
        "p_updete":"ON",
        "p_delete":"ON",
        "created_by":1
    }]







    var obj = data['privilege'];
        for (var key in obj) {
            console.log(obj[key].role_id);
        }

问题是由于 mytokenxyz 中的反斜杠没有正确转义

form: {request:[{"request":"context","sequence":0,"userToken":"mytokenxyz"}]},
