新手小白求助 request 问题

[xxxwyp]

request({
url:"https://gzmss.iok.la/api/v2/users/signin",
method: 'POST',
headers: {
"content-type": "application/json",
},
// body: JSON.stringify(userObj),
body:{'password':"123456",
'user_name':"yeungy"
},
json: true
},function(error,response,body){
console.log(body);
})

为什么这段代码会报 400 错误,用 postman 能通,通过 node 请求不行

在线等,期待大神稍微抽点时间帮忙解决,抽感激不尽!

400 错误贴一下

var request = require("request");

var options = { method: 'POST',
url: 'https://gzmss.iok.la/api/v2/users/signin',
headers:
{
'content-type': 'application/x-www-form-urlencoded' },
form: { user_name: 'yeungy', password: '123456' } };

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

console.log(body);
});
