qt客户端有实现这样的功能的库函数吗？

class UploadLinkView(APIView):

    def get(self, request, repo_id, format=None):
        if check_permission(repo_id, request.user.username) != 'rw':
            return api_error(status.HTTP_403_FORBIDDEN, "Can not access repo")

        if check_quota(repo_id) < 0:
            return api_error(HTTP_520_OPERATION_FAILED, 'Above quota')

        token = seafile_api.get_fileserver_access_token(
            repo_id, 'dummy', 'upload', request.user.username)
        url = gen_file_upload_url(token, 'upload-api')
        return Response(url)
        
        
        

qt客户端请求api，返回一个json字符串，字符串内容为一个url地址，qt客户端再去请求这个url地址。
这是文件上传功能，返回的url地址是监听8082端口的c服务。
