我正在尝试在我的应用程序中使用HttpURLConnection.我将我的请求方法设置为'GET',但是当我尝试检索输出流时,该方法将更改为'POST'!我不确定是什么原因,但是当我使用'POST'发送请求时,我的JSON服务器(我使用JAX-RS)会返回一个空白页面.

这是我的代码片段:

// Create the connection
HttpURLConnection con = (HttpURLConnection) new URL(getUrl() + uriP).openConnection();
// Add cookies if necessary
if (cookies != null) {
  for (String cookie : cookies) {
    con.addRequestProperty("Cookie", cookie);
    Log.d("JSONServer", "Added cookie: " + cookie);
  }
}
con.setDoOutput(true);
con.setDoInput(true);
con.setUseCaches(false);
con.setRequestMethod("GET");
con.setConnectTimeout(20000);
// Add 'Accept' property in header otherwise JAX-RS/CXF will answer a XML stream
con.addRequestProperty("Accept", "application/json");

// Get the output stream
OutputStream os = con.getOutputStream();

// !!!!! HERE THE REQUEST METHOD HAS BEEN CHANGED !!!!!!
OutputStreamWriter …
