Node.js HTTP请求没有返回完整响应 [英] Node.js HTTP request not returning full response
本文介绍了Node.js HTTP请求没有返回完整响应的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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
,返回的块似乎不满足完整的请求响应。这是我的代码:
var req = http.request(httpOptions,function(res){
res.setEncoding( 'utf8');
});
$ b req.on('response',function(response){
response.on('data',function(chunk){
console.log(chunk);
callback(null,JSON.parse(chunk));
});
});
$ b 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输出?难道我做错了什么?
解决方案
您还应该听取'结束'事件
< pre $
req.on('response',function(response){
var data =;
response.on 'data',function(chunk){
console.log(chunk);
data + = chunk;
});
response.on('end ',function(){
callback(data);
})
});
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();
Is there a way to wait for the full output before ending the request? Am I doing something wrong? Thanks!
解决方案
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);
})
});
