ios 上传图片file文件格式

一般我们都会base64上传图片,代码如下：

- (void)uploadPhotoToSrver:(UIImage *) image withPhotoID:(NSString *)photoID andPhotoType:(PhotoType)type andImageText:(NSString *)text {
    static int upLoadCount = 0;
    NSData *imageData = UIImageJPEGRepresentation(scaledImg, 0.6); 
    NSString *dataStr = [imageData base64EncodedStringWithOptions:0];
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/xml"];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
//参数
    NSDictionary *parameters = @{@"UserID" : userInfo.UserID,  @"imageDataStr": dataStr};
// url String
    NSString *baseURL = [NSString stringWithFormat: @"%@%@", WEBBASEURL, WEBUploadPhotoDataAction];

    [manager POST:baseURL parameters:parameters success:^(AFHTTPRequestOperation *operation,id responseObject) {
        NSLog(@"上传成功");
    }failure:^(AFHTTPRequestOperation *operation,NSError *error) {
        MYNSLOG(@"~~~~~~~~%@",error);
    }];
    
}

然后服务器要求file文件格式上传：
服务器要求需要传入的参数下图所示：

具体通过AFN实现代码如下所示：

NSData *imageData = [NSData dataWithData:UIImageJPEGRepresentation(image, 1)];
ECGFeedbackInfo *info = [[ECGFeedbackInfo alloc]init];
info.imageData = imageData;
info.feedbackOpinion = @"bug-bug-bug";
info.phoneNum = @“1888888888”；
 [[ECGpatientService sharedInstance] uploadFeedbckImageWithFeedbackInfo:info alertContent:alertContent success:^(id obj) {
        NSLog(@"用户反馈意见上传成功");
        successBlcok();
    } fail:^{
         NSLog(@"用户反馈意见上传失败");
  }];

- (void)uploadFeedbckImageWithFeedbackInfo:(ECGFeedbackInfo *)info alertContent:(NSString *)content success:(SuccessBlockWithObject)success fail:(void (^)())fail {
    
    NSString *url = @“你的URL地址”;
    NSDictionary *parameter = [NSDictionary
                               dictionaryWithObjectsAndKeys:info.phoneNum,@"phone",info.feedbackOpinion,nil];
  
    [ECGAFNetWorking uploadFeedbackImageWithURLString:url content:content parameters:parameter uploadDatas:info.imageData  completeSuccess:^(NSDictionary *respinseDic, id responseObject) {
        EcgResponseMessage *responseMessage = [[EcgResponseMessage alloc] initWithPropertyDictionary:respinseDic];
        success(responseMessage);
    } completeFailure:^{
        fail();
    }];
}
