Question

我是node.js的新手，并开始创建一个在端口5000运行的小型网络应用程序。当我尝试在本地运行的这个网址（通过浏览器或通过卷曲），一切正常，我得到回应。但是，当我尝试使用誓言进行'BDD'时，我尝试将其与http客户端连接，测试打破了，结果消息是

✗ 

  /GET
    ✗ should respond with 404
    ***TypeError: Cannot read property 'status' of undefined***

此处的回复未定义。

body = "Not found"; 
response.writeHead(404, {'Content-Type': 'text/plain', 'Content-Length': body.length});     
response.end(body);

这就是我在应用程序中的响应方式。我已经设置了标题内容类型和内容长度。任何人都可以帮我解决可能出现的问题吗？

我写的誓言就是这个。

var http = require('http'),
    vows = require('vows'),
    assert = require('assert');

vows.describe("notification").addBatch({
  "/GET": {
    topic: function() {
    http.get({host: 'localhost', port: 1337, path: '/', method: 'GET'}, this.callback) ; 
    },
    'should respond with 404': function(e,res) {
      assert.equal(res.status, 404);
    }
  }
}).run();

Answer 1

我对代码进行了更改，并尝试将响应作为回调的第一个参数，并将错误作为第二个参数。这对我有用。

'should respond with 404': function(res,e) {
   assert.equal(res.status, 404);
}

然而，如上所述，res作为唯一的参数仍然会引起错误感谢您的支持。

Answer 2

尝试更改

'should respond with 404': function(e,res) {
  assert.equal(res.status, 404);
}

到

'should respond with 404': function(res) {
  assert.equal(res.status, 404);
}

根据Node.js HTTP docs，http.request（以及http.get）回调不会带err个参数。

使用http客户端连接时，Node.js响应未定义
