app.get('/', function(req, res){
var options = {
host: 'www.google.com'
};
http.get(options, function(http_res) {
http_res.on('data', function (chunk) {
res.send('BODY: ' + chunk);
});
res.end("");
});
});
我正在尝试下载google.com主页,然后重新打印,但我收到了“发送后无法使用可变标头API”。错误
任何人都知道为什么?或如何进行http呼叫?

查看node.js doc。
上的示例here方法http.get
是一种方便的方法,它处理GET请求的许多基本内容,它通常没有主体。下面是如何发出简单HTTP GET请求的示例。
var http = require("http");
var options = {
host: 'www.google.com'
};
http.get(options, function (http_res) {
// initialize the container for our data
var data = "";
// this event fires many times, each time collecting another piece of the response
http_res.on("data", function (chunk) {
// append this chunk to our growing `data` var
data += chunk;
});
// this event fires *one* time, after all the `data` events/chunks have been gathered
http_res.on("end", function () {
// you can use res.send instead of console.log to output via express
console.log(data);
});
});
