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
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.
