如何将JSON GET请求转换为HTTP PATCH请求

Question

我想将HTTP GET请求转换为HTTP PATCH请求。我正在访问TFS API，我想通过使用补丁请求自动锁定我的构建。

目前我正在通过GET方法获取所有信息。现在我想使用HTTPPATCH方法将keepForever从false更新为true。通过GET方法，我可以做到这一点，但现在我必须通过HTTPPatch方法来做到。

有人能帮我把下面的代码从GET方法转换成POST方法吗？

public class Test_URL_Req {
public static String getURLResponse(String url) {
try {
System.out.println("nSending 'GET' request to URL : " + url);
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("GET");
con.setRequestProperty("Accept", "application/json");
int responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
// System.out.println(response);
}
in.close();
return response.toString();
} catch (Exception e) {
System.out.println(e);
}
return null;
}
public static void main(String[] args) throws JSONException{
String url = "https://tfs.tpsonline.com/IRIS%204.0%20Collection/Main/_apis/build/definitions?api-version=4.1";
//String url1 ="https://tfs.tpsonline.com/IRIS%204.0%20Collection/Main/_apis/build/builds?api-version=4.1&definitions=" + Def_id +"&resultFilter=succeeded&$top=1";
String response  = getURLResponse(url);
// String response1  = getURLResponse(url1);
JSONObject obj_JSONObject = new JSONObject(response.toString());
JSONArray obj_JSONArray = obj_JSONObject.getJSONArray("value");
String Def_id=null;
for(int i=0; i<obj_JSONArray.length();i++)
{
JSONObject obj_JSONObject2 = obj_JSONArray.getJSONObject(i);
String value = obj_JSONObject2.getString("name");
String toSearch= "DEVOPS";
if(value.equals(toSearch)){
System.out.println("STATUS:-");
System.out.println(value);
String result =obj_JSONObject2.getString("name");
System.out.println("BUILD NAME");
System.out.println(result);
Def_id = obj_JSONObject2.get("id").toString();
System.out.println("DEFINATION ID");
System.out.println(Def_id);
break;
}
}
if (Def_id != null)
{
String url1 ="https://tfs.tpsonline.com/IRIS%204.0%20Collection/Main/_apis/build/builds?api-version=4.1&definitions=" + Def_id +"&resultFilter=succeeded&$top=1";

//System.out.println(value);

if(value.equals(toSearch1)){
System.out.println("#######################################");
System.out.println("RESULT");
System.out.println(value);
String result =obj_JSONObject2.getString("status");
System.out.println("STATUS");
System.out.println(result);
Build_id = obj_JSONObject2.get("id").toString();
System.out.println("BUILD ID");
System.out.println(Build_id);

//boolean  keepForever =obj_JSONObject2.getBoolean("keepForever");
//if(keepForever == false)
//{
//  keepForever=true;
//}
// System.out.println(keepForever);
}
}
if (Build_id != null)

String url2= "https://tfs.tpsonline.com/IRIS%204.0%20Collection/Main/_apis/build/builds?api-version=4.1&buildNumber=" + Build_id;

if(value.equals(toSearch1)){
boolean keepForever =obj_JSONObject3.put("keepForever", false) != null;
if(keepForever == false)
{
keepForever = true;
}
System.out.println("#######################################");
System.out.println(keepForever);
}
}
}
}
}
}

您只需使用以下内容即可构建PATCH请求。但是，您也应该确保您的服务器支持PATCH，因为它通常不受支持。

public static String getPatchResponse( String url){
try {
System.out.println("nSending 'PATCH' request to URL : " + url);
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("PATCH");
con.setRequestProperty("Accept", "application/json");
int responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
//System.out.println(response);
}
in.close();
return  response.toString();
} catch (Exception e) {
System.out.println(e);
}
return null;
}
