我想使用 Express 发送 AJAX 请求。我正在运行如下代码:
var express = require('express');
var app = express();
app.get('/', function(req, res) {
// here I would like to make an external
// request to another server
});
app.listen(3000);
我该怎么做?

您可以使用请求库
var request = require('request');
request('http://localhost:6000', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Print the body of response.
}
})
您不需要 Express 来发出传出 HTTP 请求。为此使用本机模块:
var http = require('http');
var options = {
host: 'example.com',
port: '80',
path: '/path',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': post_data.length
}
};
var req = http.request(options, function(res) {
// response is here
});
// write the request parameters
req.write('post=data&is=specified&like=this');
req.end();
由于您只是提出一个获取请求,我建议这个 https://nodejs.org/api/http.html#http_http_get_options_callback
var http = require('http');
http.get("http://www.google.com/index.html", function(res) {
console.log("Got response: " + res.statusCode);
if(res.statusCode == 200) {
console.log("Got value: " + res.statusMessage);
}
}).on('error', function(e) {
console.log("Got error: " + e.message);
});
