利用AFN上传多张图片到服务器

最近服务器做了一个可以支持多张图片上传的接口,所以我对应的也找了AFN多图片上传的方法

这里我主要是针对UImage数组的传入,我觉得大部分我都是能获得UImage来上传的,然而在网上找到的方法都是要获得图片的地址,所以就自己整了这个

#pragma mark - 上传图片
- (void)uploadImages:(NSArray <UIImage *>*)images
{
    WEAKSELF;
    AFHTTPSessionManager *mar = [AFHTTPSessionManager manager];
    NSMutableDictionary *params = [NSMutableDictionary dictionary];
   //添加服务器需要你传的参数 params
    
    NSString *url = nil;
    //拼接地址
    url = [NSString stringWithFormat:@"%@%@", BASE_URL, URL_SHOP_IMAGE_UPLOAD];
    
    [mar POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        
        //拼接图片
        [images enumerateObjectsUsingBlock:^(UIImage * _Nonnull image, NSUInteger idx, BOOL * _Nonnull stop) {
            
            NSData *imageData = UIImagePNGRepresentation(image);
            
            if (imageData.length >= 1024 * 1024) {
                //因为我们服务器有限制1M以内   所以我超过1M的进行压缩了 
                imageData = [image resetSizeOfImageData:image maxSize:1000];
                [formData appendPartWithFileData:imageData name:@"kinta" fileName:@"kinta.jpg" mimeType:@"image/jpg"];
            }else{
                
                [formData appendPartWithFileData:imageData name:@"kinta" fileName:@"kinta.png" mimeType:@"image/png"];
            }

        }];
        
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        
        // 回到主队列刷新UI,用户自定义的进度条
        dispatch_async(dispatch_get_main_queue(), ^{
            [SVProgressHUD showProgress:1.0 *
             uploadProgress.completedUnitCount / uploadProgress.totalUnitCount];
        });
        
        
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        
        NSLog(@"上传成功 %@", responseObject);
        
        id datalist = responseObject[@"datalist"];
       
        NSLog(@"%@",datalist);
        
       
            
        } else {
        
        }
        
        
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        
        NSLog(@"上传失败 %@", error);
        [SVProgressHUD dismiss];
    }];
    
}
