使用struts框架接受http请求过来的get和post数据的方法：

http发送get/post请求：

public static void main(String[] args) {
	//发送get请求
	String geturl = "127.0.0.1:8080/user/serviceapi.do?operation=getUser&userID=" + 1234;
	OkhttpUtil.syncGet(geturl);
		
	//发送post请求
	String posturl = "127.0.0.1:8080/user/serviceapi.do?operation=getUserModel";
	JSONObject jsonStr = new JSONObject();
	jsonStr.put("username", "李白");
	jsonStr.put("studentid", "2018001");
	OkhttpUtil.syncPost(posturl, jsonStr.toString());
}

struts框架中获取请求过来的数据：

获取get过来的请求：

@Component("/user/serviceapi")
public class ApiAction extends DispatchAction{
	public void getUser(ActionMapping mapping,ActionForm form,
			HttpServletRequest request,HttpServletResponse response){
		String userID = request.getParameter("userID");
		HttpClientUtil.writeJSONStringToClient(response, "success");
	}
}

 

获取post过来的请求：

@Component("/user/serviceapi")
public class ApiAction extends DispatchAction{

	public void getUserModel(ActionMapping mapping,ActionForm form,
			HttpServletRequest request,HttpServletResponse response){
		ActionContext ctx = ActionContext.getContext();
		String jsonStr = this.getRequestBody(ctx,request);
		JSONObject json = JSONObject.fromObject(jsonStr);
		if(json.containsKey("username")){
			String username = json.getString("username");
		}
		if(json.containsKey("studentid")){
			String studentid = json.getString("studentid");
		}
		HttpClientUtil.writeJSONStringToClient(response, "success");
	}
	
	public String getRequestBody(ActionContext ctx,HttpServletRequest request){
        try {
            InputStream inputStream = request.getInputStream();
            String strMessage = "";
            StringBuffer buff = new StringBuffer();
            BufferedReader bufferReader = new BufferedReader(new         
                                  InputStreamReader(inputStream,"utf-8")); 
            while((strMessage = bufferReader.readLine()) != null){
                buff.append(strMessage);
            }
            bufferReader.close();
            inputStream.close();
            return buff.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}
