请解决我的问题...

推荐答案

您可以使用base64字符串上传图像。首先将图像转换为客户端中使用服务的base64字符串。并在服务中将base64字符串转换为图像。

You can use base64 string to upload an image. First convert an image to base64 string in client from where your service is used. and in service convert that base64 string to image.

我也尝试使用base64字符串，但只能上传非常小的图像，如何上传大图像???

I also tried using base64 string, but only very small size image can be uploaded, how to upload large Image ???
