You don't need Express to make an outgoing HTTP request. Use the native module for that:
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();

Since you are simply making a get request I suggest this https://nodejs.org/api/http.html#http_http_get_options_callback
由于您只是提出获取请求，因此我建议使用 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);
});
