 </HTML>

    我认为这是因为我还没有迁移到不推荐使用的云端点v1.1到V2.0

    但是在我做了迁移所需的更改之后,当我尝试部署它时,它仍然返回503,同时运行Maven命令来部署或生成文档。

    我知道谷歌说他们正在经历 issues

    我的应用程序引擎应用程序正在使用美国中部地区。

    更新 :看起来cloud endpoint V1.1已关闭,无法再提供流量服务,因此根据迁移指南,我已能够迁移到版本2.0,但不幸的是,我在api发现文档中遇到错误

    这就是错误

    API发现响应缺少必需字段。

    我正试着绕开这件事

    我猜这个错误被发布到一些第三方库中,可能仍然使用任何旧的云端点maven依赖项或插件。所以我会从我的pom.xml文件并尝试部署。

    我在一个端点上遇到了同样的问题,这个端点已经有几个月没有更改了,日志中也没有出现任何内容。我想这可能是应用程序引擎的问题。

    编辑

    https://cloud.google.com/endpoints/docs/frameworks/python/migrating .

    文件上说v1.1将于8月2日关闭,我想他们已经有时间了

    我已经成功地迁移到端点V2后,一系列的命中和试验方法。

    在androidstudio上开发的appengine项目具有以下结构-

    项目

    • 应用程序
    • 后端
    • 构建.gradle

    让我们一个一个地改变。

    /应用程序/构建.gradle 

    dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:26.+'

// Remove this line
//compile project(path: ':micirclews', configuration: 'android-endpoints')

    } 

    apply plugin: 'com.google.cloud.tools.endpoints-framework-client'

    /后端/构建.gradle (在backend/appengine模块中进行更改) 

    buildscript {
repositories {
    mavenCentral()
    jcenter()
}
dependencies {
    //Remove this
    //classpath 'com.google.appengine:gradle-appengine-plugin:1.9.59'

    //Add these two lines
    classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.2'
    classpath 'com.google.cloud.tools:appengine-gradle-plugin:1.3.3'
}

    }

    删除此- apply plugin: 'appengine' 

    apply plugin: 'com.google.cloud.tools.appengine'
apply plugin: 'com.google.cloud.tools.endpoints-framework-server'


dependencies {
//Remove these 3 lines-
//appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.59'
//compile 'com.google.appengine:appengine-endpoints:1.9.59'
//compile 'com.google.appengine:appengine-endpoints-deps:1.9.59'

//Add these 2 lines-
compile 'com.google.endpoints:endpoints-framework:2.0.9'
compile 'javax.inject:javax.inject:1'
.....

    } 

    // delete this whole block, it's configuration for the older plugin
// appengine {
//   downloadSdk = true
//   appcfg {
//     oauth2 = true
//   }
//   endpoints {
//     getClientLibsOnBuild = true
//     getDiscoveryDocsOnBuild = true
//   }
// }

    /构建.gradle (在根目录中进行更改)构建.gradle) 

    buildscript {
repositories {
    jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:2.3.3'

    //Add these 2 lines
    classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.2'
    classpath 'com.google.cloud.tools:appengine-gradle-plugin:1.3.3'
}

    在仔细地进行所有更改之后,请清理项目,重新生成并运行它。最后在一切正常时部署它。

    你可以在这里介绍整个过程- https://github.com/GoogleCloudPlatform/endpoints-framework-gradle-plugin/blob/master/ANDROID_README.md

    正如saiyr在评论中所说的,googlecloudendpointsv1.1已经被完全弃用,并且已经停止服务于流量,这就是我所犯错误的原因。 我通过迁移到cloudendpoints v2解决了这个问题,这个过程非常简单,只需遵循 migration docs 但这里有一些关于迁移的问题,以及我是如何解决的。

    2. 如果您有多个服务类,则必须将它们添加到网站.xml在声明 com.google.api.server.spi.EndpointsServlet Servlet。 com.google.api.server.spi.SystemServiceServlet Servlet,我认为它与Objectify过滤器有关。 See the Docs for more info

    3. 由于googleappenginejava7运行时也不受欢迎,我决定迁移到java8,但不幸的是,我用来抽象连接到数据存储(Objectify)的过程的库似乎不能与java8运行时一起工作,我稍后会对此进行研究,但恢复到java7运行时对我来说是可行的,应用程序也会备份还有跑步。

    更新 :迁移到Java 8运行时时遇到的问题与Objectify无关,我用于加密密码的库(BCrypt)就是问题所在,它只是在Google App Engine Java 8运行时不起作用,我不得不在spring security中切换到加密库。
