Question

我一直在尝试使用Java连接Bitly REST API。我想使用Bitly API中的缩短方法。这是我的代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.log4j.BasicConfigurator;

public class PostRequestClient {
    public static void main(String[] args) {
        // TODO Auto-generated method stub

         try {
             BasicConfigurator.configure();
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost postRequest = new HttpPost(
                    "https://api-ssl.bitly.com/v3/shorten");

                StringEntity input = new StringEntity("{\"access_token\":<my_access_token>,\"longUrl\":\"https://docs.appian.com/suite/help/18.1/Custom_Function_Plug-ins.html\"}");
                input.setContentType("application/json");
                postRequest.setEntity(input);

                HttpResponse response = httpClient.execute(postRequest);

                if (response.getStatusLine().getStatusCode() != 201) {
                    throw new RuntimeException("Failed : HTTP error code : "
                        + response.getStatusLine().getStatusCode());
                }

                BufferedReader br = new BufferedReader(
                                new InputStreamReader((response.getEntity().getContent())));

                String output;
                System.out.println("Output from Server .... \n");
                while ((output = br.readLine()) != null) {
                    System.out.println(output);
                }

                httpClient.getConnectionManager().shutdown();

              } catch (MalformedURLException e) {

                e.printStackTrace();

              } catch (IOException e) {

                e.printStackTrace();

              }

    }
}

我已从https://www.mkyong.com/webservices/jax-rs/restful-java-client-with-apache-httpclient/引用此代码。请告诉我你是否正确地调用了这个有点api的想法。我收到了以下错误：

如果你能给我一些输入来解决这个错误，我将不胜感激。

谢谢！
