问题描述
我正在尝试连接到 Google Drive API,但我一直收到返回“未捕获的类型错误:无法在 initClient 读取未定义的属性 'init'。”
我不知道该怎么做才能解决这个问题。
这是我运行的代码:
`enter code here`var CLIENT_ID = ' ';
var API_KEY = ' ';
// Array of API discovery doc URLs for APIs used by the quickstart
var disCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/drive/v3/rest"];
// Authorization scopes required by the API; multiple scopes can be
// included,separated by spaces.
var ScopES = 'https://www.googleapis.com/auth/drive.readonly';
var FILES = {};
function handleClientLoad() {
setTimeout(function(){ gapi.load('client',initClient()); },3000);
}
function initClient() {
gapi.client.init({
apiKey: API_KEY,clientId: CLIENT_ID,discoveryDocs: disCOVERY_DOCS,scope: ScopES
}).then(function () {
// Listen for sign-in state changes.
gapi.auth2.getAuthInstance().isSignedIn.listen(updateSigninStatus);
// Handle the initial sign-in state.
updateSigninStatus(gapi.auth2.getAuthInstance().isSignedIn.get());
authorizeButton.onclick = handleAuthClick();
signoutButton.onclick = handleSignoutClick();
},function(error) {
console.log(JSON.stringify(error,null,2));
});
return gapi;
}
我按照建议进行了更改,但仍然无法正常工作。我不确定我做错了什么!这是更新后的代码:
`enter code here`var CLIENT_ID = ' ';
var API_KEY = ' ';
// Array of API discovery doc URLs for APIs used by the quickstart
var disCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/drive/v3/rest"];
// Authorization scopes required by the API; multiple scopes can be
// included,separated by spaces.
var ScopES = 'https://www.googleapis.com/auth/drive.readonly';
var FILES = {};
function handleClientLoad() {
setTimeout(function(){ gapi.load('client:auth2',initClient); },2));
});
return gapi;
}
还有其他建议吗?谢谢!
解决方法
gapi.load 接受一个回调函数,但你传递给它的是 initClient() 的输出。
其次,您需要加载 OAuth2 库 (auth2)。
改变这个:
function handleClientLoad() {
setTimeout(function() { gapi.load('client',initClient()); },3000);
为此:
function handleClientLoad() {
setTimeout(function() { gapi.load('client:auth2',initClient); },3000);
附注。如果您将代码放在问题的文本中,而不是屏幕截图中,那么其他人剪切粘贴答案会容易得多。
