1：AFNetworking简称为AFN,是对NSURLConnection,NSURLSession的一层封装
2:使用：现在项目中导入AFNetworking，在头文件中包含，即
#import "AFNetworking.h"
下面我就直接贴代码了，里面有详细的解释
用get方法,解析json
-(void)getjson{ //1.创建一个请求管理者 AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager]; //声明一下:服务器返回的是json数据,默认返回的是json数据，所以不用声明 //mgr.responseSerializer = [AFJSONResponseSerializer serializer]; //responseObject 类型是NSDictionary或者是NSArray //2.请求参数, NSMutableDictionary *params = [NSMutableDictionary dictionary]; params[@"Service"] = @"adminCoach"; params[@"Loginname"] = @"admim"; params[@"Page"] = @"1"; //3.发送一个get请求 NSString *url = @"http://localhost:8080/Jiaxiao2/admin.php/Appadmin/index"; [mgr GET:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { //请求成功时调用这个block NSLog(@"请求成功-----%@",responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //请求失败时调用这个block NSLog(@"请求失败"); }]; } 用get方法,解析XML
-(void)getXML{ //1.创建一个请求管理者 AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager]; //声明一下:服务器返回的是XML数据 //responseObject 类型是NSXMLParser mgr.responseSerializer = [AFXMLParserResponseSerializer serializer]; //2.请求参数 NSMutableDictionary *params = [NSMutableDictionary dictionary]; params[@"username"] = @"123"; params[@"pwd"] = @"345"; params[@"type"] = @"XML"; //3.发送一个get请求，返回来的是NSXMLParser NSString *url = @"http://localhost:8080/zhong/login"; [mgr GET:url parameters:params success:^(AFHTTPRequestOperation *operation, NSXMLParser *responseObject) { //请求成功时调用这个block NSLog(@"请求成功-----%@",responseObject); //对NSXMLParser进行解析 //设置代理// responseObject.delegate =self;// [responseObject parse]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //请求失败时调用这个block NSLog(@"请求失败"); }];} 用get方法,解析data
-(void)getData{ //1.创建一个请求管理者 AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager]; //声明一下:服务器返回的是data数据,即不要对服务器返回的数据进行解析，直接返回data即可 //文件下载肯定是用这个 //responseObject 类型是NSData mgr.responseSerializer = [AFHTTPResponseSerializer serializer]; //2.请求参数 NSMutableDictionary *params = [NSMutableDictionary dictionary]; params[@"username"] = @"123"; params[@"pwd"] = @"345"; //3.发送一个get请求，返回来的是NSXMLParser NSString *url = @"http://localhost:8080/zhong/login"; [mgr GET:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { //请求成功时调用这个block NSLog(@"请求成功-----%@",[responseObject class]);// //返回的是xml时// NSXMLParser *parser = [[NSXMLParser alloc]initWithData:responseObject];// //返回的是json时// NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //请求失败时调用这个block NSLog(@"请求失败"); }];} 用post方法,解析json
-(void)postjson{ //1.创建一个请求管理者 AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager]; //声明一下:服务器返回的是json数据,默认返回的是json数据，所以不用声明 //mgr.responseSerializer = [AFJSONResponseSerializer serializer]; //responseObject 类型是NSDictionary或者是NSArray //2.请求参数, NSMutableDictionary *params = [NSMutableDictionary dictionary]; params[@"Service"] = @"adminCoach"; params[@"Loginname"] = @"admim"; params[@"Page"] = @"1"; //3.发送一个POST请求 NSString *url = @"http://localhost:8080/Jiaxiao2/admin.php/Appadmin/index"; [mgr POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { //请求成功时调用这个block NSLog(@"请求成功-----%@",responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //请求失败时调用这个block NSLog(@"请求失败"); }]; } -(void)getSession{ //AFHTTPSessionManager 对NSURLSession的封装 AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager]; [mgr GET:@"" parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) { } failure:^(NSURLSessionDataTask *task, NSError *error) { }];} 转载地址：http://fxrvb.baihongyu.com/
