AFNetwork学习（二）——GET/POST请求

为了学习AFNetwork,自己搭建整理了一下AFNetwork向后台发送请求和后台返回json数据的整个处理过程。利用Struts2搭建了一个后台，提供Action并返回json数据

环境：Xcode6.3

后台：tomcat+myeclipse10.6  框架：struts2

1.新建一个single-view application工程名为IOS_AFNetwork,开发语言选择OC.

2.将AFNetwork库文件加入到工程中，如下图：

3.引入SystemConfiguration.framework、MobileCoreService.framework、Security.framework 。如下图：

4.在main.storyboard中添加两个按钮，发别用来发送get和post请求,并设置对应的响应函数。如下图：

5.发送Get请求

//get请求- (IBAction)getRuquest:(id)sender {    //为了测试方便，自己搭建了一个javaweb后台    NSString *URLString = @"http://localhost:8080/server/login.action";    //传递参数    NSDictionary *loginInputValue = @{@"username" : @"1234567890",                                      @"password" : @"123456"};    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.requestSerializer.timeoutInterval = self.timeInternal;    manager.responseSerializer = [AFHTTPResponseSerializer serializer];    self.operation = [manager GET:URLString                       parameters:loginInputValue                          success:^(AFHTTPRequestOperation *operation, id responseObject) {                             //解析后台返回的json串，将json转为字典                              NSDictionary *responseData = [NSDictionary dictionaryFromJSONData:(NSData *)responseObject];                              NSLog(@"success:%@",responseData);                              NSString *name = [responseData objectForKey:@"name"];                              NSLog(@"name : %@",name);                          }                          failure:^(AFHTTPRequestOperation *operation, NSError *error) {                              NSLog(@"error info :%@",[error description]);                          }];}

6.发送Post请求

- (IBAction)postRequest:(id)sender {        NSString *URLString = @"http://localhost:8080/server/login.action";    NSDictionary *loginInputValue = @{@"username" : @"1234567890",                                      @"password" : @"123456"};    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.requestSerializer.timeoutInterval = self.timeInternal;    manager.responseSerializer = [AFHTTPResponseSerializer serializer];       self.operation =  [manager POST:URLString                         parameters:loginInputValue                            success:^(AFHTTPRequestOperation *operation, id responseObject) {                            NSDictionary *responseData = [NSDictionary dictionaryFromJSONData:(NSData *)responseObject];                            NSString *name = [responseData objectForKey:@"name"];                            NSLog(@"name : %@",name);                            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error info :%@",[error description]);    }];}
