6. API 版本验证

平台需要在每次调用 Open Service Broker API 时提供 HTTP 标头，以指示平台支持的 API 规范版本。 您可以配置 Spring Cloud Open Service Broker 以验证平台在每次调用 Service Broker 时提供的版本。 默认情况下，此版本验证配置为允许任何 API 版本。spring-doc.cadn.net.cn

要自定义版本验证，请将apiVersion指定 Service Broker 所需的 API 版本的属性，如下所示：spring-doc.cadn.net.cn

spring.cloud.openservicebroker.apiVersion=2.13

或者，您也可以提供BrokerApiVersionSpring bean 中，如下所示：spring-doc.cadn.net.cn

package com.example.servicebroker;

import org.springframework.cloud.servicebroker.model.BrokerApiVersion;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ExampleApiVersionConfiguration {
	@Bean
	public BrokerApiVersion brokerApiVersion() {
		return new BrokerApiVersion("2.13");
	}
}

In the case of both a Spring Bean and a property being configured, the Spring Bean takes precedence over the property.spring-doc.cadn.net.cn

If an API version is specified and the platform provides a different version in the X-Broker-API-Version header, the framework returns a 412 Precondition Failed error to the platform.spring-doc.cadn.net.cn

As mentioned earlier, the default version verification is configured to allow any API version. However, to disable version verification entirely, you can set the api-version-check-endabled property to false, as follows:spring-doc.cadn.net.cn

spring.cloud.openservicebroker.api-version-check-enabled = false
