iOS使用AFN上传单张、多张图片

iOS在上传图片时，AFN专门封装了一个上传文件的方法，但是这里需要特别强调的是name和mineType

[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file%d",i+1] fileName:[NSString stringWithFormat:@"file%d.jpg/png",i+1] mimeType:@"image/jpeg"];

name：服务器后台文件名的key，后台会根据这个字段获取相应的图片字节流

data: 需要上传的二进制数据

fileName：文件名带上后缀

mineType：文件类型

方法调用：

+ (void)uploadImagesWithImages:(NSArray<UIImage *> *)imageArray url:(NSString *)urlStr Parameters:(NSDictionary *)parameters success:(void (^)(id responseObject))success failure:(void (^)(NSError *error))failure {    [manager POST:urlStr parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {        int imageCount = 0;        for (UIImage *image in imageArray) {            NSString *mineType = @"image/jpeg";            NSString *str =@"";            if (UIImagePNGRepresentation(image)) {                mineType = @"image/png";                str = @"png";            }else {                mineType = @"image/jpeg";                str = @"jpeg";            }            NSData *data = UIImageJPEGRepresentation(image, 0.30);            [formData appendPartWithFileData:data name:[NSString stringWithFormat:@"file%d",imageCount] fileName:[NSString stringWithFormat:@"icon%d.%@",imageCount,str] mimeType:mineType];            imageCount++;        }    } progress:^(NSProgress * _Nonnull uploadProgress) {        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {        success(responseObject);    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {        failure(error);    }];}
