客戶端程式碼

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
        manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
        NSDictionary *dict = @{@"method":@"setAddress",@"username":@"lisi",@"address":@"beijing"};
        [manager POST:USERSERVLET_PATH parameters:dict success:^(AFHTTPRequestOperation *operation, id
 
 responseObject) {
            NSString *status = [responseObject objectForKey:@"status"];
            if([@"success" isEqualToString:status]){
                NSLog(@"設定Address成功");
                //更新UI
                _addressLabel.text = address;
            }
        } failure:^(AFHTTPRequestOperation *operation, NSError
 
 *error) {
            NSLog(@"設定Address失敗");
        }];

伺服器用的是java的servlet

        PrintWriter out = null;
        try {
            out = response.getWriter();
            String address = request.getParameter("address");
            //要想通過此方法取得引數值,客戶端要這樣設定(預設就是此配置,可以不寫)
            //manager.requestSerializer
 
 = [AFHTTPRequestSerializer serializer];
            String username = request.getParameter("username");
            UserDao dao = new UserDaoImpl();
            String status = dao.setAddress(username,address);
            Map<String,String> map = new HashMap<String,String>();
            map.put("status", status);
            JSONObject result = JSONObject.fromMap(map);
            out.print(result.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            out.flush();
            out.close();
        }
