[英]Parse.com REST API Error Code 400: Bad Request from Java HTTP Request to Cloud Function
[英]HTTP PATCH request to TFS REST API from java application getting 400 (bad request) error
我正在嘗試通過Java代碼向TFS REST API發出HTTP PATCH請求。 但是我得到了400個錯誤的請求代碼。 我的POST和GET方法從Java運行。
我有以下代碼:
public static void patchCenas() throws MalformedURLException, IOException{
URL url = new URL("http://servername:8080/tfs/DefaultCollection/Testing%20Project/_apis/wit/workitems/$Bug?api-version=1.0");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setConnectTimeout(15000);//15 secs
connection.setReadTimeout(15000);//15 secs
connection.setRequestProperty("X-HTTP-Method-Override", "PATCH");
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "{\"Content-Type\":\"application/json-patch+json\"}");
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(
"[" +
"{"+
"\"op\":\"add\"," +
"\"path\":\"/fields/System.Title\"," +
"\"value\":\"Bug with PATCH via java (Test)\""+
"}"+
"]");
out.flush();
out.close();
int res = connection.getResponseCode();
System.out.println(connection.getResponseMessage());
System.out.println(res);
BufferedReader br = new BufferedReader(new InputStreamReader(((HttpURLConnection) url.openConnection()).getInputStream(), Charset.forName("UTF-8")));
//InputStream is = connection.getInputStream();
//BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line = null;
while((line = br.readLine() ) != null) {
System.out.println(line);
}
connection.disconnect();
}
消息:
響應消息:錯誤的請求
響應碼:400
行輸出:

我的代碼有問題嗎?
我測試了您上面發布的代碼段。 內容類型不正確。 更改為:
connection.setRequestProperty("Content-Type", "application/json-patch+json");
它不需要{}
