【问题描述】:
您好,我正在发送数据的服务器期望图像为文件(jpg)而不是 NSData。此代码有效,但服务器无法将 NSData 识别为图像。任何想法如何解决这个问题?
+ (void)signupWithParameters:(NSDictionary *)parameters
andUserHaveImage:(BOOL)userHaveImage
andImage:(NSData *)image
successBlock:(void (^) (NSDictionary *response))successHandler
errorBlock:(void (^) (NSDictionary *error))errorHandler
{
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"multipart/formdata" forHTTPHeaderField:@"Content-Type"];
[manager POST:[NSString stringWithFormat:@"%@/api/1.0/customer/sign-up", DEFAULT_URL] parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
if (userHaveImage == YES) {
//
[formData appendPartWithFileData:image name:@"img_profile" fileName:@"profileImage.jpg" mimeType:@"image/jpg"];
[formData appendPartWithFormData:image name:@"img_profile"];
}
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
successHandler(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
errorHandler(@{});
}];
}
【问题讨论】:
-
Stefan 您是通过 UIImageJPEGRepresentation 还是 UIImagePNGRepresentation 将图像转换为数据?
-
NSData *imageData = UIImageJPEGRepresentation(self.profileImageView.image, 1);是的,那个服务器人告诉我他看到了这些数据,但他期待的是文件(image.jpg)
-
meme 类型,试试这个@"image/jpeg"
-
也试过了,同样的问题...谢谢建议...
-
[formData appendPartWithFormData:图像名称:@"img_profile"];这不应该存在
