我正在尝试使用以下代码从外部网址获取响应，但我没有运气。有人可以阐明我做错了什么，并给出他们认为可能有帮助的任何指示。

var express = require('express'),
              require('events');

var app = express.createServer();

app.request({
    host: "http://ws.audioscrobbler.com",
    port: 80,
    method: "GET",
    path: "/2.0/?method=artist.getsimilar&artist=bandname&api_key=b25b959554ed76058ac220b7b2e0a026"
}).on('response',function(response) {
    console.log(response);
});

app.listen(4000);

I'm trying to get a response from an outside url using the below code, but im having no luck. Can someone shed some light on what I'm doing wrong and give any pointers they think could be helpful.

var express = require('express'),
              require('events');

var app = express.createServer();

app.request({
    host: "http://ws.audioscrobbler.com",
    port: 80,
    method: "GET",
    path: "/2.0/?method=artist.getsimilar&artist=bandname&api_key=b25b959554ed76058ac220b7b2e0a026"
}).on('response',function(response) {
    console.log(response);
});

app.listen(4000);

我不知道你是否可以。您可以只使用内置的请求功能（请参阅这个：

来自网站：

var http = require('http');

var options = {
    host: 'www.google.com',
    port: 80,
    path: '/upload',
    method: 'POST'
};

var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
    });
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

这非常简单，您仍然可以在现有代码中使用它...

有时框架没有针对所有问题的解决方案...文档是您的朋友。

I don't know if you can. You could just use the built-in request function (see this:

From the website:

var http = require('http');

var options = {
    host: 'www.google.com',
    port: 80,
    path: '/upload',
    method: 'POST'
};

var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
    });
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

It's pretty easy and you can still use it in your existing code...

Sometimes frameworks don't have solutions for everything... the documentation is your friend.
