Question

我正在研究Google Cloud Endpoints，我对配置有些怀疑。我已经使用了appengine，但是端点对我来说有点混乱。

我做了这个例子：

https://cloud.google.com/endpoints/docs/frameworks/java/get-started-frameworks-java

我为测试其他可能性做了一些更改：

应用服务引擎-web.xml中

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <runtime>java8</runtime>
    <threadsafe>true</threadsafe>

    <module>endpointsmodule</module>


    <basic-scaling>
        <max-instances>1</max-instances>
    </basic-scaling>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>

    <!-- [START env_variables] -->
    <env-variables>
        <env-var name="ENDPOINTS_SERVICE_NAME" value="${endpoints.service.prefix}.endpoints.${endpoints.project.id}.appspot.com" />
        <env-var name="ENDPOINTS_SERVICE_VERSION" value="1.0.0" />
    </env-variables>
    <!-- [END env_variables] -->
</appengine-web-app>

的web.xml

 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <!-- Wrap the backend with Endpoints Frameworks v2. -->
    <servlet>
        <servlet-name>EndpointsServlet</servlet-name>
        <servlet-class>com.google.api.server.spi.EndpointsServlet</servlet-class>
        <init-param>
            <param-name>services</param-name>

    </servlet>

    </servlet-mapping>

        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

    <!-- Add a filter that fetches the service config from service management. -->
    <filter>
        <filter-name>endpoints-api-configuration</filter-name>
        <filter-class>com.google.api.control.ServiceManagementConfigFilter</filter-class>
    </filter>

    <!-- Add a filter that performs Endpoints logging and monitoring. -->
    <!-- [START api_management] -->
    <filter>
        <filter-name>endpoints-api-controller</filter-name>
        <filter-class>com.google.api.control.extensions.appengine.GoogleAppEngineControlFilter</filter-class>
        <init-param>
            <param-name>endpoints.projectId</param-name>
            <param-value>${endpoints.project.id}</param-value>
        </init-param>
        <init-param>
            <param-name>endpoints.serviceName</param-name>
            <param-value>${endpoints.service.prefix}.endpoints.${endpoints.project.id}.appspot.com</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>endpoints-api-configuration</filter-name>
        <servlet-name>EndpointsServlet</servlet-name>

    </filter-mapping>

    <filter-mapping>
        <filter-name>endpoints-api-controller</filter-name>
        <servlet-name>EndpointsServlet</servlet-name>
    </filter-mapping>
    <!-- [END api_management] -->
</web-app>

的pom.xml

<endpoints.project.id>myprojectid</endpoints.project.id>
<endpoints.service.prefix>mymodule</endpoints.service.prefix>

openapi.json

{
 "swagger": "2.0",
 "info": {
  "version": "1.0.0",
  "title": "xxx"
 },
 "host": "myprojectid.appspot.com",
 "basePath": "/endpointsmodule",
 "schemes": [
  "https"
 ],

怀疑是：

什么是service_name的目的？我确实部署了openapi.json和appengine模块，但在我的Google控制台中仍然以“服务名称”显示我的项目名称。

此配置：ENDPOINTS_CONFIG_ID，我在Google控制台的任何位置都看不到。

我希望我的端点在“enpoints-module”（appengine）中接收requets，它是appengine，而不是默认模块。

所有对端点的请求都是通过_ah / api发生的？

我正在尝试为此路径发出请求： https://myprojectid.appspot.com/endpointsmodule/echo/v1/echo

ENDPOINTS_CONFIG_ID和ENDPOINTS_SERVICE_VERSION的正确值是什么？

appengine开始时的异常：

repackaged.com.google.api.config.ServiceConfigException: Failed to fetch default config version for service 'myserviceprefix.endpoints.myprojectid.appspot.com'. No versions exist!

Answer 1

端点服务名称是OpenAPI规范中设置的主机字段。这必须匹配环境变量ENDPOINTS_SERVICE_NAME和endpoints.serviceName过滤器参数。
