[英]Why am I receiving 500 error in response to my JSON request?
我正在嘗試將JSON發送到服務器,但它不斷返回500錯誤。
java.lang.String contentToPost = jsarray.toJSONString();
java.net.URLConnection connection = new java.net.URL("http://example.com/service?apiKey=12345").openConnection();
connection.setUseCaches(false);
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestProperty("Content-Length", "" + contentToPost.length());
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Cache-Control", "no-cache");
java.io.OutputStream stream = connection.getOutputStream();
stream.write(contentToPost.getBytes());
stream.close();
System.err.println("request is sent");
// Read the response
java.io.BufferedReader br = new java.io.BufferedReader(new java.io.InputStreamReader(connection.getInputStream()));
java.lang.StringBuffer sb = new java.lang.StringBuffer();
java.lang.String str = br.readLine();
while (str != null) {
sb.append(str);
str = br.readLine();
}
br.close();
java.lang.String responseString = sb.toString();
System.err.println(responseString);
錯誤
java.io.IOException: Server returned HTTP response code: 500 for URL: http://example.com/service?apiKey=12345
