问题

预研访问国外厂商云api相关的代码，发现请求国外厂商云获取token时，发生了下面的错误：

com.google.auth.oauth2.GoogleAuthException: Error getting access token for service account: connect timed out, iss: testmanagebucket@esoteric-cab-458306-c2.iam.gserviceaccount.comat com.google.auth.oauth2.GoogleAuthException.createWithTokenEndpointIOException(GoogleAuthException.java:163)at com.google.auth.oauth2.ServiceAccountCredentials.refreshAccessToken(ServiceAccountCredentials.java:546)at com.google.auth.oauth2.OAuth2Credentials$1.call(OAuth2Credentials.java:270)at com.google.auth.oauth2.OAuth2Credentials$1.call(OAuth2Credentials.java:267)at java.util.concurrent.FutureTask.run(FutureTask.java:266)at com.google.auth.oauth2.OAuth2Credentials$RefreshTask.run(OAuth2Credentials.java:635)at com.google.common.util.concurrent.DirectExecutor.execute(DirectExecutor.java:31)at com.google.auth.oauth2.OAuth2Credentials$AsyncRefreshResult.executeIfNew(OAuth2Credentials.java:582)at com.google.auth.oauth2.OAuth2Credentials.asyncFetch(OAuth2Credentials.java:233)at com.google.auth.oauth2.OAuth2Credentials.refreshIfExpired(OAuth2Credentials.java:204)at com.google.cloud.Demo.main(Demo.java:25)

经过检查，发现是因为电脑直连国外云厂商相关的域名，被ban了。

解决方案

准备好代理服务，如果代理服务使用的是shadowsocks服务协议，则可以在代码里面加上Java的系统属性配置代理，需要在GoogleCredentials之前设置代理系统属性：

        System.setProperty("socksProxyHost", "Your_socks_proxy_host_一般是127.0.0.1");System.setProperty("socksProxyPort","通过下图所示获取到10808");

在这里插入图片描述

代码验证

java代码

public class Demo {public static void main(String[] args) throws IOException {System.setProperty("socksProxyHost", "127.0.0.1");System.setProperty("socksProxyPort","10808");String serviceAccountPath = "C:\\Data\\googleserviceaccount.json";try {GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream(serviceAccountPath)).createScoped(new ArrayList<>(Collections.singleton("https://www.googleapis.com/auth/cloud-platform")));credentials.refreshIfExpired();String token = String.valueOf(credentials.getAccessToken());System.out.println(token);} catch (Exception e) {e.printStackTrace();System.out.println(e.getMessage());}return ;}
}
对应的maven要引入下面所示的依赖代码包<dependency><groupId>com.google.api-client</groupId><artifactId>google-api-client</artifactId><version>2.7.1</version></dependency><dependency><groupId>com.google.auth</groupId><artifactId>google-auth-library-bom</artifactId><version>1.34.0</version></dependency>

执行结果

返回了目标token
