我正在尝试按照此文档与Google登录集成，尽管我在控制台中遇到了此错误：
Uncaught TypeError: Cannot read property 'load' of undefinedat script.js:1
script.js：
window.gapi.load('auth2', function() {
console.log('Loaded!');
});
我大约一半的时间收到错误，并在Chrome中检查网络面板，仅在未加载以下资源时发生：
https://apis.google.com/_/scs/apps-static/_/js/k=oz.gapi.en.d2dliHDvPwE.O/m=auth2/exm=signin2/rt=j/sv=1/d=1/ed=1/am=AQ/rs=AGLTcCNGAKhVlpzmTUpjFgzBXLpLM_oEFg/cb=gapi.loaded_1
如何消除此错误？
如果它有用，这是我的index.html：
<!DOCTYPE html>
<html>
<head>
<title>Google Sign In Test</title>
<meta name="google-signin-client_id" content="*****.apps.googleusercontent.com">
<script src="https://apis.google.com/js/platform.js" async defer></script>
<script src="script.js" async defer></script>
</head>
<body>
<div class="g-signin2" data-onsuccess="onSignIn"></div>
</body>
</html>
尝试将 onload 事件添加到脚本标记。因此，请将脚本标记更改为
<script src="https://apis.google.com/js/platform.js?onload=myFunc" async defer></script>
然后将代码包装在回调函数中。
将onload参数添加到链接中，如文档中所示： 谷歌登录文档
如果你在纯html/js中这样做，你可以把这个摘录添加到head标签中。
<script src="https://apis.google.com/js/platform.js?onload=myFunc" async defer></script>
<script>
function init() {
gapi.load('auth2', function() { // Ready. });
}
</script>
如果你想在反应应用程序中加载 gepi(例如 create-react-app)，请尝试将其添加到组件中：
loadGapiAndAfterwardsInitAuth() {
const script = document.createElement("script");
script.src = "https://apis.google.com/js/platform.js";
script.async = true;
script.defer = true;
script.onload=this.initAuth;
const meta = document.createElement("meta");
meta.name="google-signin-client_id";
meta.content="%REACT_APP_GOOGLE_ID_OF_WEB_CLIENT%";
document.head.appendChild(meta);
document.head.appendChild(script);
}
initAuth() {
window.gapi.load('auth2', function () {
window.gapi.auth2.init({
client_id: "%REACT_APP_GOOGLE_ID_OF_WEB_CLIENT%";
}).then(googleAuth => {
if (googleAuth) {
if (googleAuth.isSignedIn.get()) {
const googleUser = googleAuth.currentUser.get();
// do something with the googleUser
}
}
})
});
}
