golang appengine - 文件名太长答案

【问题标题】：golang appengine - filename too longgolang appengine - 文件名太长

【问题描述】：

我在 GO 中开发了一个 appengine 应用程序，现在我尝试使用 androidpublisher api。为此，我需要许多依赖项，例如：

github.com/google/google-api-go-client
github.com/golang/oauth2
google.golang.org/appengine
google.golang.org/appengine/urlfetch

我尝试根据https://github.com/golang/oauth2 中的示例为 google-api-go-client 设置 oauth2 身份验证

一切看起来都很好，但我不能再在我的 Windows 开发机器上运行应用服务器了。它抱怨文件名太长：

我认为我的 GOPATH 设置错误，因此他将所有 gofile 作为参数提供给 go-app-builder.exe。

我的项目在C:\Users\me\project\ 下，这是 gopath 指向的位置，并且当我输入时我正站立：

goapp.bat serve .

有人可以帮忙解决这个问题吗？谢谢。

我的项目结构是这样的：我应该如何设置我的 GOPATH？

GOPATH
  $GOPATH
       app.yaml
       cron.yaml
       pkg
       src
            testapp
                 app.go
        golang.org
            x
                  oauth2

我试图将我的 GOPATH 移动到 project-root-dir/gopath 但现在我收到以下错误消息：

对于所有非德国用户，它抱怨参数错误

【问题讨论】：

不要传递点.，只需以goapp serve 开头。这能解决吗？
使用命令 goapp.bat serve <path to directory containing app.yaml> 或 cd 到该目录并运行 goapp.bat serve。如果这不能解决问题，请查看stackoverflow.com/questions/38711615/…。您可能有 GOPATH 指向应用程序目录。
goapp serve 没有修复它。是的，我的 GOPATH 指向 appdirectiory。我用我当前的目录结构编辑了我的帖子。

标签： python google-app-engine go google-api-go-client

【解决方案1】：

我通过设置我的 GOPATH 解决了这个问题。

现在是这样设置的：

GOPATH=C:\Users\me\development\appengine\gopath;C:\Users\me\project

现在一切正常，上传的文件现在要小得多。 2MB 与 11MB。

感谢您的提示。
