问题

有没有办法在使用Go编写的App Engine应用程序上运行编译器，而不需要继续使用开发服务器来提供应用程序，并且能够获取退出代码？

因为我想在Travis的自动化测试中添加一个检查，确保应用程序实际上可以编译。

**澄清一下：**我在Travis中可以访问App Engine SDK / 开发服务器，但我不想运行goapp serve，因为它永远不会退出。

你的解决方案看起来很不正规，没有实际实施测试。为什么不使用goapp build呢？这是我的.travis.yml文件：

language: go
go:
- 1.2.1

# 获取最新版本并下载
install:
    - export FILE=go_appengine_sdk_linux_amd64-$(curl https://appengine.google.com/api/updatecheck | grep release | grep -o '[0-9\.]*').zip
    - curl -O https://storage.googleapis.com/appengine-sdks/featured/$FILE
    - unzip -q $FILE

# 运行构建和测试
script:
    - ./go_appengine/goapp test ./tests; # 如果你正在进行测试
    - ./go_appengine/goapp build ./packagedir; # 你保存东西的地方

已经过了一段时间，但我最近注意到我的一些构建会随机失败。这真是令人恼火，我偶尔会硬编码SDK的值来解决这个问题。不再这样做了。这是一个非常不正规的实现，用于获取所需SDK的第一个特色版本（因为/updatecheck无法始终返回托管版本）：

```bash
export FILE=$(curl https://storage.googleapis.com/appengine-sdks/ | grep -o 'featured/go_appengine_sdk_linux_amd64-[^\<]*' | head -1)

只获取文件名：

export FILE=$(curl https://storage.googleapis.com/appengine-sdks/ | grep -oP '(?<=featured/)go_appengine_sdk_linux_amd64-[^\<]*' | head -1)

Without actually implementing test, your solution looks pretty hacky. Why not use `goapp build`? Here&#39;s my `.travis.yml`:

    language: go
    go:
    - 1.2.1

    # Grab newest version and suck down
    install:
        - export FILE=go_appengine_sdk_linux_amd64-$(curl https://appengine.google.com/api/updatecheck | grep release | grep -o &#39;[0-9\.]*&#39;).zip
        - curl -O https://storage.googleapis.com/appengine-sdks/featured/$FILE
        - unzip -q $FILE

    # Run build and tests
    script:
        - ./go_appengine/goapp test ./tests; # If you are testing
        - ./go_appengine/goapp build ./packagedir; # Wherever you keep your stuff

It has been awhile, but I noticed recently that some of my builds randomly break. It is infuriating and I have occasionally hardcoded SDK values to overcome this. No more. Here&#39;s a very hacky implementation of grabbing the first featured (and thus hosted as /updatecheck fails to always return a hosted version) of the SDK desired:

    export FILE=$(curl https://storage.googleapis.com/appengine-sdks/ | grep -o &#39;featured/go_appengine_sdk_linux_amd64-[^\&lt;]*&#39; | head -1)

For just the file:

    export FILE=$(curl https://storage.googleapis.com/appengine-sdks/ | grep -oP &#39;(?&lt;=featured/)go_appengine_sdk_linux_amd64-[^\&lt;]*&#39; | head -1)

我通过在应用程序的入口点（main_test.go）添加一个空的单元测试来解决了这个问题。这个单元测试将强制整个应用程序进行编译。

然后，我通过在**script**部分中添加**goapp test ./...**来执行所有的单元测试。

I solved this by adding an empty Unit test at the entry point of the application (main_test.go). This unit test will force the whole application to compile.

Then I execute all unit tests by putting **goapp test ./...** in the **script** section.
