我一直在处理一个问题,我必须将一个io.Reader实例作为参数放入由 api 作为端点提供的函数中。我需要做的任务是将本地文件夹上传到公司的云存储。
func (s *server) uploadFileToPutIo(w http.ResponseWriter, r *http.Request) {
tokenSource := oauth2.StaticTokenSource(&oauth2.Token{AccessToken: token})
oauthClient := oauth2.NewClient(context.TODO(), tokenSource)
client := putio.NewClient(oauthClient)
var testIO io.Reader // ?
upload, err := client.Files.Upload(context.TODO(), testIO, "test", 0)
if err != nil {
log.Fatal(err)
}
fmt.Println(upload.File)
sendResponse(w, []byte("successful"), http.StatusOK)
}
/upload当我在 POST 方法下向这个端点发出请求时。我收到以下错误。
