为什么这不起作用？我也尝试过使用HttpURLConnection类，但是这也没用。 php页面找不到发布的数据。注意：我很新用java发布请求。

public static String GetURL(String inUrl, String post) {
    String inputLine = "";
    try {
        if (!inUrl.contains("http")) {
            throw new Exception("Invalid URL");
        } else {
            Log.writeLog(inUrl);
            URL url = new URL(inUrl);

            //send post
            URLConnection connection = url.openConnection(); 
            //connection.setRequestMethod("POST"); 
            connection.setDoOutput(true);
            connection.setRequestProperty("Accept-Charset", "UTF-8");
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
            connection.connect();

            OutputStream wr = connection.getOutputStream();
            wr.write(post.getBytes());
            wr.flush();
            wr.close();

            BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
            inputLine = in.readLine();
            in.close();
        }
    } catch (Exception ex) {
        ex.printStackTrace();
        Log.writeLog("Error getting url.");
    }

    return inputLine;
}

由于您没有指定错误，因此我很难看到您出错的地方。

但是，我认为使用像HttpClient这样的抽象会容易得多。你的代码看起来像这样：

URI uri = new URIBuilder()
        .setURI(inUrl)
        .addHeader("Accept-Charset", "UTF-8")
        .addHeader("Content-Type", "application/x-www-form-urlencoded")
        .build();
HttpPost httpPost = new HttpPost(uri);
httpPost.setEntity(post);

比处理流和连接的低级细节要清晰得多。

Java Post请求不起作用
