我需要帮助解决这个问题。
我正在向服务器发送POST请求,处理一些对象创建和编辑。 REST在Android和Android中运行良好iOS,我的桌面应用程序的代码类似
问题在于,当我尝试发送数据时,除了登录数据(也使用帖子,并且工作正常,返回令牌和所有内容)之外,我得到了这个疯狂的错误:
java.io.IOException: Server returned HTTP response code: 500 for URL: http://some.url/api/save
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1839)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1440)
POST方法,适用于登录:
public String POST(String targetURL, String urlParameters, int selector) {
URL url;
HttpURLConnection connection = null;
try {
url = new URL(targetURL);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
if (selector != 1) {
connection.setRequestProperty("Authorization", "Bearer "
+ Constantes.user.getToken());
}
connection.setRequestProperty("Content-Type", "plain/text");
connection.setUseCaches(false);
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setReadTimeout(120000); // Send
DataOutputStream wr = new DataOutputStream(
connection.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
// Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
this.setResponseCode(connection.getResponseCode());
while ((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
return response.toString();
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
if (connection != null) {
connection.disconnect();
}
}
}
我不知道发生了什么,请帮帮我 提前谢谢!
