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 applicationproject名为IOS_AFNetwork,开发语言选择OC.
2.将AFNetwork库文件增加到project中，例如以下图：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="400" height="420" border="1" alt="">
3.引入SystemConfiguration.framework、MobileCoreService.framework、Security.framework 。例如以下图：
4.在main.storyboard中加入两个button。发别用来发送get和post请求,并设置相应的响应函数。
例如以下图：
5.发送Get请求
//get请求
- (IBAction)getRuquest:(id)sender {
//为了測试方便。自己搭建了一个javaweb后台
NSString *URLString = @"http://localhost:8080/server/login.action";
//传递參数
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]); }];
}
