无法使用Gmail API获取Gmail只读邮件.这里使用的语言是html和javascript

Question

我写了三个文件，分别是：home-flatfull.jsp、settings-social-prefs.html和google-js-api-wrapper.js文件。

在home-flatfull.jsp文件中，我写了如下内容：

head.js('jscore/lib/base64.js', 'jscore/lib/google-js-api.js', 'jscore/lib/google-js-api-wrapper.js', function () {
var config = {
apiKey: 'AIzaSyCa52K8J68kr5b4S7Afu1FQzeleCfvzOFs',
clientId: '492662354647-877atvgj1a0pu82nrutsm50rcmg0lufh.apps.googleusercontent.com',
discoveryDocs: ["https://www.googleapis.com/discovery/v1/apis/gmail/v1/rest"],
scopes: 'https://www.googleapis.com/auth/gmail.readonly',
listener: function(response){
console.log(' Check google ');
console.log(response);
}
};
googleJSAPI = GoogleJSAPI.getInstance(config);
});

在settings-social-prefs.html文件中，我定义如下：

<a onclick="googleJSAPI.signIn()" class="btn btn-sm btn-default">
{{agile_lng_translate 'prefs-email' 'enable'}}
</a>

在google-js-api-wrapper.js文件中，我定义如下：

class GoogleJSAPI {
emailRegx = /^(([^<>()[]\.,;:s@"]+(.[^<>()[]\.,;:s@"]+)*)|(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/;
instance;
isActive = false;
constructor(config) {
console.log(' google code loaded ');
gapi.load('client:auth2', () => {
gapi.client.init({
apiKey: config.apiKey,
clientId: config.clientId,
discoveryDocs: config.discoveryDocs,
scope: config.scopes
}).then(() => {
this.isActive = true;
console.log(' config loaded ');
gapi.auth2.getAuthInstance().isSignedIn.listen(config.listener);
}, (error) => {
this.isActive = false;
console.log(JSON.stringify(error, null, 2));
});
});
}
static getInstance(config) {
if (!this.instance) {
this.instance = new GoogleJSAPI(config);
}
return this.instance;
}
isActive() {
return this.isActive;
}
isUserLoggedIn() {
return gapi.auth2.getAuthInstance().isSignedIn.get();
}

gapi.auth2.getAuthInstance().signIn();

gapi.auth2.getAuthInstance().signOut();

}
}, 3000);
});
}

当我点击settings-social-prefs.html文件中的启用按钮时，我只得到了gmail登录页面和gmail密码页面。一旦我提供了gmail用户名和密码，我得到了同意屏幕，该屏幕要求允许访问用户的电子邮件，然后我得到了空白屏幕，而没有得到指定登录用户的gmail只读邮件。当我点击启用按钮时，你能帮我获取Gmail只读邮件吗。

您可以关闭双因素身份验证(如果启用(，还可以"允许低安全性的应用程序连接"；在谷歌我的帐户设置

Ps：应避免公开展示API：-(
