利用HttpClient 发送Patch请求,携带Json参数

HttpClient 中没有HttpPatch类，可以继承HttpPut来实现

import org.apache.http.client.methods.HttpPut;

public class HttpPatch extends HttpPut{
  public HttpPatch(String url) {
    super(url);
  }
  @Override
  public String getMethod(){
    return "PATCH";
  }
}

一次请求的方法如下：

public static JSONObject executeHttpPatch(String url,JSONObject jsonParam){  
        JSONObject resultObj = null;  
        HttpClient httpClient = new DefaultHttpClient();   
        HttpPatch httpPatch = new HttpPatch(url);  
        httpPatch.setHeader("Content-type", "application/json");  
        httpPatch.setHeader("Charset", HTTP.UTF_8);  
        httpPatch.setHeader("Accept", "application/json");  
        httpPatch.setHeader("Accept-Charset", HTTP.UTF_8);  
        try {  
            if (jsonParam != null){  
                StringEntity entity = new StringEntity(jsonParam.toString(),HTTP.UTF_8);  
                httpPatch.setEntity(entity);  
            }  
            HttpResponse response = httpClient.execute(httpPatch);  
            resultObj = new JSONObject(EntityUtils.toString(response.getEntity()));  
        } catch (ParseException | JSONException | IOException   e) {  
            e.printStackTrace();  
        }  
          
        return resultObj;  
    }
