我想在Xamarin.Forms应用程序上发送带有图像的SMS。
我尝试使用Xamarin.Essentials或Xamarin.Plugins中的消息,但仅支持短信。
怎么办?
答案 0 :(得分:2)
好吧,您可以将图像转换为base64字符串,您可以使用SMS发送该字符串,因为它将以文本形式表示。
由于SMS仅支持160个字符,因此这将花费很多,并且您可以在本网站上看到一个示例,该示例说明如何将图像转换为字符串,以及根据图像的大小需要占用多少空间。
据我所知,首选的方法是在将图像转换为JSON形式的base64字符串后,使用http post到服务器。然后,将其转换回图像,并将其存储在服务器中,或者对它进行任何操作。
JSON请求示例:
