AFNetworking实现网络请求

GET请求

- (IBAction)get:(id)sender {

//网址字符串
NSString *urlString = @"http://piao.163.com/m/cinema/list.html?app_id=1&mobileType=iPhone&ver=2.6&channel=appstore&deviceId=9E89CB6D-A62F-438C-8010-19278D46A8A6&apiVer=6&city=110000";
//创建http会话管理对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

//设置请求数据类型
//AFHTTPRequestSerializer key=value形式(默认)
//AFJSONRequestSerializer JSON数据形式
manager.requestSerializer = [AFHTTPRequestSerializer serializer];

//设置接受数据类型
//AFHTTPResponseSerializer 不解析数据
//AFJSONResponseSerializer JSON解析 (默认)
//AFXMLParserResponseSerializer XML解析
manager.responseSerializer =[AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingMutableLeaves];

//发起请求
[manager GET:urlString
parameters:nil
progress:^(NSProgress * _Nonnull downloadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
NSLog(@"请求成功");
NSLog(@"%@", responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"请求失败");
}];
}

POST请求

- (IBAction)post:(id)sender {

//网址字符串
NSString *urlString = @"http://piao.163.com/m/cinema/schedule.html?app_id=1&mobileType=iPhone&ver=2.6&channel=appstore&deviceId=9E89CB6D-A62F-438C-8010-19278D46A8A6&apiVer=6&city=110000";
//创建会话管理者
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//设置请求数据类型(默认)
//设置接受数据类型(默认)
//发起请求
//设置请求体参数
NSDictionary *parameters = @{@"cinema_id" : @1533};
[manager POST:urlString
parameters:parameters
progress:nil
success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

NSLog(@"请求成功");
NSLog(@"%@", responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

NSLog(@"请求失败");
}];

}

通过POST请求发送带图文的微博

- (IBAction)postWeibo:(id)sender {

NSString *urlString = @"https://upload.api.weibo.com/2/statuses/upload.json";
NSString *token = @"2.00hd363CtKpsnBedca9b3f35tBYiPD";

NSDictionary *parameters = @{@"access_token" : token,  //授权登陆
@"status" : @"这不是lip"   //微博文字
};

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager POST:urlString
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

UIImage *image = [UIImage imageNamed:@"风景.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1);

//name上传数据的参数名字
//mimeType:数据的类型名
//jpg -- image/jpeg
//png -- image/png
[formData appendPartWithFileData:imageData name:@"pic" fileName:@"ljp" mimeType:@"image/jpeg"];

}
progress:^(NSProgress * _Nonnull uploadProgress) {
//监控上传进度
NSLog(@"%.1lf", (CGFloat)uploadProgress.completedUnitCount/uploadProgress.totalUnitCount*100);
}
success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

NSLog(@"上传成功");
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"上传失败");
}];

}
