- 整个开发背景是前端在调用完google play v3 支付流程后，需要后台验证支付结果以及在自己的服务生成订单相关信息。对于服务账号的文档搜了度娘对于这块的资料少，无从下手，踩了不少坑。网上的搜出来的大多数是针对OAuth 2.0 客户端 ID的验证，需要使用到refreshAccess，但是服务账号不一样，那不需要验签通过后直接能请求查询订单。
- 用到的 maven 依赖jar包
- 登录校验
- 订单创建
- 订单成功校验
这边服务端用的是java ,在接入googgle渠道中与安卓端对接的过程就三接口，1、登录校验 2、创建订单号及校验产品id后返回订单号给安卓端 3、支付完成订单校验，google支付那没有想微信那边支付成功后回调到我们服务端，它那边是通过安卓端的请求来通知我们自己的服务端的支付成功通知，掉单的情况也是客户端来通知。。
因这边用到的是消耗型的产品，后台就省了一步acknowledge的确认，只需要校验订单支付状态。
登入前期准备以下只是格式，具体的参数从谷歌后台下载：
1、客户端秘钥，其中google_client_secret_data是我这边自己加的
{"google_client_secret_data": {
"web": {
"client_id": "123456789-1li1d7k.apps.googleusercontent.com",
"project_id": "project_id-0310",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs"
}
}
}
2、服务端秘钥其中google_service_account_data是我这边自己加的
{
"google_service_account_data": {
"type": "service_account",
"project_id": "123456789526755524298661-783",
"private_key_id": "1234567890ac89f9c70f245f1798587ae9b7",
"private_key": "-----BEGIN PRIVATE KEY-----nMIIEvQASCBKcwggSjAgEAAoIBAQCX1kMC4Au/n-----END PRIVATE KEY-----n",
"client_email": "test02661-783.iam.gserviceaccount.com",
"client_id": "123456789",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/83.iam.gserviceaccount.com"
}
}
