Java：如何使用UrlConnection发布具有授权的请求？

这里有一个很好的例子。在下面的Powerlord正确的地方，您需要POST。

HttpURLConnection

下面是执行此操作的代码，

    URL url = new URL(urlString);    URLConnection conn = url.openConnection();    conn.setDoOutput(true);    conn.setRequestProperty ("Authorization", enpredCredentials);    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());    writer.write(data);    writer.flush();    String line;    BufferedReader reader = new BufferedReader(new     InputStreamReader(conn.getInputStream()));    while ((line = reader.readLine()) != null) {      System.out.println(line);    }    writer.close();    reader.close();

更改

URLConnection

HttpURLConnection

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();    conn.setRequestMethod("POST");

建议（…中的评论）：

您可能还需要设置这些属性，

conn.setRequestProperty( "Content-type", "application/x-www-form-urlenpred");conn.setRequestProperty( "Accept", "*/*" );
