NodeJS发布请求正文未定义

Question

我正在向API发送一个简单的帖子请求，该API会检索其正文中的401和挑战标记。

如果我这样做：

curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{
"username" : "dummydata"}' "<BASER_URL>/authentication"

我可以获得所需的令牌，为php和python尝试相同，并在请求正文中获得一个令牌，但是我无法找到使用nodejs，尝试axios，request＆amp; unirest并得到相同的结果。

我做错了什么？

var request = require('request');


var options = { method: 'POST',
  url: '<BASE_URL>/authentication',
  headers:
   { 'cache-control': 'no-cache',
     'content-type': 'application/json'
    },
  body: {username: "dummydata"},
  json: true };

request(options, function (error, response, body) {
  console.log(body)
});

修改

console.log(error)

error: null

console.log(response)

response:{
    "statusCode": 401,
    "headers": {
        "set-cookie": [
            "X-HSC-PREFIX=d063b4009759",
