AFNetWorkingSession

由于iOS9废弃了NSURLConnection,所以,原本的AFNetWorking里的hettrequestmanager这个应该是不行了,虽然依然可以用,但里边仍然含有已经废弃的方法,所以这里总结一下session的用法

请求数据

//启动一个sessionManager    AFURLSessionManager * dataManager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];    //设置响应器,有三种,data ,xml JSON,这里用data 默认时JSON    dataManager.responseSerializer = [AFHTTPResponseSerializer serializer];    //初始化请求    NSURL * dataURL = [NSURL URLWithString:@"http://10.0.8.8/sns/my/user_list.php"];    NSURLRequest * dataRequest = [NSURLRequest requestWithURL:dataURL];    //请求数据    NSURLSessionDataTask * dataTask = [dataManager dataTaskWithRequest:dataRequest completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {        NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];        NSLog(@"%@",dict);    }];    [dataTask resume];

上传数据

这里说明一下,如果是上传数据的话,这种方式要用NSMutableURLRequest类来生命request,不然会出现各种错误,原作者展示的是url的上传,这个我也不是很清楚,然这样做的话,就不报错了….很奇怪

    AFURLSessionManager * uploadManager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];    uploadManager.responseSerializer = [AFHTTPResponseSerializer serializer];    NSURL * uplpadURL = [NSURL URLWithString:@"http://10.0.8.8/sns/my/upload_headimage.php"];    NSMutableURLRequest  * uploadRequest = [NSMutableURLRequest requestWithURL:uplpadURL];    UIImage * uploadImage = [UIImage imageNamed:@"10_7.jpg"];    NSData * uploadData = UIImageJPEGRepresentation(uploadImage, 1.0);    uploadRequest.HTTPMethod = @"POST";    NSURLSessionUploadTask * uploadTask = [uploadManager uploadTaskWithRequest:uploadRequest fromData:uploadData progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {        NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];        NSLog(@"%@",dict);    } ];    [uploadTask resume];

另一种上传数据

完全按照官方GitHub上写的,可以上传任意数据

    UIImage * uploadMutableImage = [UIImage imageNamed:@"10_7.jpg"];    NSData * uploadMutableData = UIImageJPEGRepresentation(uploadMutableImage, 1.0);    AFURLSessionManager * uploadMutableManager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];    uploadMutableManager.responseSerializer = [AFHTTPResponseSerializer serializer];    NSMutableURLRequest * uploadMutableRequest = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://10.0.8.8/sns/my/upload_headimage.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {        [formData appendPartWithFileData:uploadMutableData name:@"headimage" fileName:@"10_7" mimeType:@"iamge/jpeg"];    } error:nil];    NSURLSessionUploadTask * uploadMutableTask = [uploadMutableManager uploadTaskWithStreamedRequest:uploadMutableRequest progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {       NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];       NSLog(@"mutableUpLoad : %@",dict);   }];    [uploadMutableTask resume];
