这是我第一次尝试在 Android Studio 项目中使用 GAE 端点连接。因此，我只是按照 Google ( https://cloud.google.com/tools/android-studio/app_engine/) 提供的说明进行操作。但是每次我尝试构建或运行后端模块时都会收到 403 错误。这是消息:
Error:Execution failed for task ':backend:appengineEndpointsGetClientLibs'.
> There was an error running endpoints command get-client-lib: 403 Forbidden

通常我可以通过在“设置”中启用代理来抑制此类问题。但是对于这个错误，在谷歌搜索了 3 天并尝试了我脑海中闪过的所有解决方案之后，没有任何改变。有人遇到过同样的错误吗？或者知道解决方案/建议？
编辑 我正在运行带有示例 MyBean 和 MyEndpoint 类的模板端点项目，没有任何更改。这是相关的 build.gradle 文件:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.google.appengine:gradle-appengine-plugin:1.9.18'
}
}
repositories {
mavenCentral();
}
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'appengine'
sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7
dependencies {
appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.18'
compile 'com.google.appengine:appengine-endpoints:1.9.18'
compile 'com.google.appengine:appengine-endpoints-deps:1.9.18'
compile 'javax.servlet:servlet-api:2.5'
}
appengine {
downloadSdk = true
appcfg {
oauth2 = true
}
endpoints {
getClientLibsOnBuild = true
getDiscoveryDocsOnBuild = true
}
}
最佳答案
谷歌阻止包括伊朗在内的一些国家的人访问 http://developer.google.com和 http://apis.google.com , 所以你遇到了问题。
出于隐私、可移植性和其他几个方面的考虑，您无论如何都应该避免使用 Google App Engine。
Portability concerns
Developers worry that the applications will not be portable from App Engine and fear being locked into the technology. In response, there are a number of projects to create open-source back-ends for the various proprietary/closed APIs of app engine, especially the datastore. AppScale, CapeDwarf and TyphoonAE are a few of the open source efforts.

您可以使用这些替代方案。
