Node.js HTTP 请求未返回完整响应 [英] Node.js HTTP request not returning full response

问题描述

我正在使用 Node 的 http 模块发出一个 HTTP 请求，但是在 data 上，返回的块似乎不满足完整的请求响应.这是我的代码:

I'm making a HTTP request using Node's http module, but on data, the chunk returned doesn't seem to content the full request response. Here's my code:

var req = http.request(httpOptions, function(res) {
    res.setEncoding('utf8');
});

req.on('response', function (response) {
    response.on('data', function (chunk) {
        console.log(chunk);
        callback(null, JSON.parse(chunk));
    });
});

req.on('error', function(e) {
    callback(e);
    //callback(e.message);
});

req.end();

有没有办法在结束请求之前等待完整的输出?难道我做错了什么?谢谢！

Is there a way to wait for the full output before ending the request? Am I doing something wrong? Thanks!

推荐答案

你也应该监听 'end' 事件

you should also listen for the 'end' event

req.on('response', function (response) {

    var data = "";

    response.on('data', function (chunk) {
        console.log(chunk);
        data += chunk;
    });

    response.on('end', function(){
        callback(data);
    })

});
