Question

我有一个node.js，它等待带有2个参数（名称和传递）的帖子：

app.post('/login.html', function (req, res) {

    log.info(req.body);
    userName = req.body.name;
    pass = req.body.pass;
    ...
}

我试图通过简单的Java应用程序发送带有2个参数的帖子，但我看不到它到达了node.js。

我想念什么？

java代码：

public static void main(String[] args) {
    URL url;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL("http://83.63.118.111:31011/login.html");

        urlConnection = (HttpURLConnection) url.openConnection();               
        urlConnection.setReadTimeout(10000);
        urlConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");

        urlConnection.setConnectTimeout(10000);
        urlConnection.setRequestMethod("POST");
        urlConnection.setDoInput(true);
        urlConnection.setDoOutput(true);

        OutputStream os = urlConnection.getOutputStream();
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));          
        String str = "name='root'&pass='123456'";
        //System.out.print(str);
        writer.write(str);
        writer.flush();
        Thread.sleep(100);
        writer.close();
        os.close();       
}

开始发送数据（发送和停止）时，您的代码将关闭

您应该等待它完成。

在writer.flush();之后添加代码

示例获取response：

BufferedReader in = new BufferedReader(
        new InputStreamReader(urlConnection.getInputStream()));
String inputLine;
StringBuilder response = new StringBuilder();

while ((inputLine = in.readLine()) != null) {
    response.append(inputLine);
}
in.close();

或仅获得responseCode：

int responseCode = urlConnection.getResponseCode();

您的程序等待发送请求成功还是失败。

我认为您使用Thread.sleep(100);等待发送请求，但它会停止您的线程（不向服务器发送数据）

您的代码有req.body，Express.js没有，需要使用中间件body-parser。

使用HttpURLConnection发送帖子
