AFHTTPRequestOperationManager的底层使用了NSOperation，并且使用的是NSURLConnection，可支持iOS6及更新的系统版本；AFURLSessionManager使用的是更新的NSURLSession，支持iOS7.0以上系统。本人强烈建议使用AFURLSessionManager除非你要使用operations或者需要支持iOS6。3.0的AFNetowrking使用AFHttpSessionManager代替AFHTTPRequestOperationManager，请注意！
下面来写一下AFURLSessionManager的上传图片方法：
//上传图片
- (void)requestUploadPhotoWithImage:(UIImage *)image withSucess:(HLSucessBlock)success failure:(HLFailureBlock)failure
{
NSData *imagedata = UIImageJPEGRepresentation(image, 0.7f);
NSString *urlString = [NSString stringWithFormat:@"%@%@",HLNETWORK_BASE_URL_TEST,kUrl_UploadImages];
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableDictionary *params = [NSMutableDictionary dictionary];
NSString *token = [HLFitmentManager instance].userInfo.token;
if (CHECK_VALID_STRING(token)) {
[params setObject:token forKey:@"token"];
}
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:@"POST" URLString:urlString parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"%@.jpg",str];
[formData appendPartWithFileData:imagedata name:@"image" fileName:fileName mimeType:@"image/jpeg"];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) {
//进度
} completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
HLParser *parser = [[HLParser alloc] init];
BOOL isError = [parser hasErrorWithDict:responseObject];
if (isError) {
//上传图片失败
NSLog(@"上传图片失败");
failure(nil,parser.error);
}else {
NSLog(@"上传图片成功");
success(nil,responseObject);
}
}];
[uploadTask resume];
}
