谷歌选择器身份验证弹出窗口被阻止

Kev*_*Sol 9 javascript oauth popup google-drive-api

我有一个列出工作的移动网站,用户申请并上传他们的简历(简历) - 我希望他们能够从他们的Google云端硬盘中选择一个文件.

我在这里创建了Hello world示例 - https://developers.google.com/picker/docs/(为方便起见,此处转载的代码)

问题是,如果尚未登录到云端硬盘,则会启动登录弹出窗口.这在桌面上已经够糟了,但在手机上真的很糟糕.

我试过这个解决方案,但得到'TypeError:gapi.auth is undefined'

我还尝试从onclick事件启动选择器,而不是文档描述的onload.

function launchDrive()
    {
        gapi.load('auth', {'callback': onAuthApiLoad});
        gapi.load('picker', {'callback': onPickerApiLoad});
    }
<input type='button' value='Launch Drive' onclick='launchDrive();'>

继Jason的回答之后,这也是我也尝试过的(通过oncllick按钮调用):

function launchDrive()
    {
        //gapi.load('auth', {'callback': onAuthApiLoad});
        gapi.auth.init(onAuthApiLoad);
        gapi.load('picker', {'callback': onPickerApiLoad});
    }

您将需要调用gapi.auth.init。请参阅此处的文档：https ://developers.google.com/api-client-library/javascript/reference/referencedocs#gapiauthinit

初始化授权功能。当客户端加载时调用此方法，以防止弹出窗口阻止程序阻止gapi.auth.authorize 调用上的身份验证窗口。
