问题描述

我是所有这些东西的新手，并且我正在开发一个插件.我需要使用libcurl上传文件.问题在于该文件不在磁盘上，其内容上的指针传递给了我的插件.所以我的问题是要上传文件，我需要FILE * var，但是我有void *.我该怎么办?

I'm a complete newbie to all this stuff, and I'm developing a plugin. I need to upload a file using libcurl. The problem is that that file is not on the disk, pointer on it's content is passed to my plugin. So my question is that to upload a file I need FILE* var, but I'm having void*. What should I do?

提前谢谢！

推荐答案

您可以使用读取回调执行上载，而不是提供FILE *，如

You can perform an upload using a read callback instead of providing a FILE *, as specified in this example. In the callback then you can copy into the given buffer the data to upload.
