The web page loaded by WKWebView cannot upload video to Qiniu.

App uses WKWebView to load the link. The loaded web page has a button that can be used to upload video to Qiniu. There has been no response after choosing to upload the video, but I opened this link with QQ and then uploaded the video. I found that it can be uploaded successfully. Does webview need to make any special settings?
