在java中使用PATCH API(之前的问题已被删除)

Question

我必须在java中使用PATCH API。当我尝试在下面的代码中使用时，它会给出异常

java.net.ProtocolException: Invalid HTTP method: PATCH
at java.net.HttpURLConnection.setRequestMethod(Unknown Source)
at sun.net.www.protocol.http.HttpURLConnection.setRequestMethod(Unknown Source)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.setRequestMethod(Unknown Source)
at com.java.jackson.jackson.PatchRequest.main(PatchRequest.java:32)

下面代码中的这一行引发异常。

connection.setRequestMethod("PATCH");

我正在使用以下代码进行相同的操作。

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;

String targetUrl="https://xxxxxxxxx-t0.data.digitalassistant.oci.oc-test.com/api/v1/bots/"+botID+"/dynamicEntities/"+dynamicEntityId+"/pushRequests/"+pushRequestId+"/values";

connection=(HttpURLConnection) url.openConnection();
connection.setUseCaches (false);
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("PATCH");

BufferedReader reader =new BufferedReader(in);

String apiOutput="";
while((output=reader.readLine())!=null) {
apiOutput+=output;
}
System.out.println(apiOutput);  
connection.disconnect();
}
} catch(Exception e) {
e.printStackTrace();
}
}
}

我在谷歌中阅读，然后我用低于 2 行替换了引发异常的行。

connection.setRequestProperty("X-HTTP-Method-Override", "PATCH");
connection.setRequestMethod("POST");

然后它抛出Http status code 412.你能帮我同样的忙吗？

您将无法使用java.net.HttpURLConnection在下面的链接中查看详细信息。您需要在java.net.http包中使用客户端 API。
