如何测试在 Node.js 中接收流/分块数据？

发布于 2024-12-29 17:50:27 字数 373 浏览 2 评论 0原文

我一直在探索 node.js api，并且遇到了 HTTP 服务器的“data”事件。我的问题是：假设有一个像下面这样非常简单的应用程序，我如何发送数据并调试流？

var http = require("http");

http.createServer(function(req, res) {
    req.setEncoding("utf8");
    req.on("data", function(data){
        console.log("request:\n" + data);
    });
}).listen(3000, "127.0.0.1");

我尝试过使用telnet和curl来发送请求，但没有取得任何成功。谢谢大家！

I've been exploring the node.js api, and I ran across the "data" event for HTTP servers. My question is this: assuming a dead-simple app like below, how could I send data, and debug the stream?

var http = require("http");

http.createServer(function(req, res) {
    req.setEncoding("utf8");
    req.on("data", function(data){
        console.log("request:\n" + data);
    });
}).listen(3000, "127.0.0.1");

I've tried using telnet and curl to send requests, but I haven't had any success. Thanks all!

看来我混淆了 HTTP 和 TCP。如果您编写 TCP 服务器，而不是 HTTP 服务器：

var net = require("net");

net.createServer(function(req, res){
    req.on("data", function (data) {
        console.log("request:" + data);
    });
}).listen(3000, "127.0.0.1");

您可以轻松地通过 telnet（或 netcat）测试/调试到服务器的流数据：

$ telnet 127.0.0.1 3000

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

It seems I was confusing HTTP and TCP. If you write a TCP server, rather than an HTTP server:

var net = require("net");

net.createServer(function(req, res){
    req.on("data", function (data) {
        console.log("request:" + data);
    });
}).listen(3000, "127.0.0.1");

you can easily test/debug streaming data to the server via telnet (or netcat):

$ telnet 127.0.0.1 3000

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
