android – 如何使用google-play-purchase-validator有效购买快递服务器

我希望将Google Play应用内结算功能整合到已经获得payLoad json的Unity项目中.我有一台Node.js服务器,想要获得Google Play购买响应的价值,以便进行服务器端验证.

我在Google Play开发者控制台上的列表产品是创建productId但我收到错误：

在我的节点服务器的index.js文件中,我有一个这样的段：

var Verifier = require('google-play-purchase-validator');
var options = {
    email: '#############-compute@developer.gserviceaccount.com',key: '-----BEGIN PRIVATE KEY-----##some private key##-----END PRIVATE KEY-----',keyFile: './Google Play Android Developer-############.json'
};
var verifier = new Verifier(options);
var receipt = {
    packageName:"com.natekgames.######",productId:"com.natekgames.######.diamond_48",purchaseToken:"ihfeaepjoppolibmeknoghmo.AO-J1OxbHPDa8QLVAU3OqvIa-ZgaAGWhrBhs8DyCEfFbbdTCH8ecvEXQlZtjkqaowPXujb0Osn_aOWBPMT0OpTMcivoQalEtOZmMhS2lDA7oH868NjZP2LgdE9ODafujNM7O9QQr3-hq"
};
verifier.verify(receipt,function cb(err,response){
    if(err){
        console.log("there was an error validating the receipt");
        console.log(err);
    }
    console.log("sucessfully validated the receipt");
    res.send(response);
});
