1.獲取未授權(quán)Request
// 1.定義字符串保存登錄界面URL
let urlStr = "https://api.weibo.com/oauth2/authorize?client_id=4129759360&redirect_uri=http://www.520it.com"
// 2.創(chuàng)建URL
guard let url = URL(string: urlStr) else
{
return
}
// 3.創(chuàng)建Request
let request = URLRequest(url: url)
// 4.加載登錄界面
customWebView.loadRequest(request)
2.獲取已經(jīng)授權(quán)Request
extension OAuthViewController: UIWebViewDelegate

// 該方法每次請求都會調(diào)用
// 如果返回false代表不允許請求, 如果返回true代表允許請求
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {

通過觀察
1.如果是授權(quán)成功獲取失敗都會跳轉(zhuǎn)到授權(quán)回調(diào)頁面
2.如果授權(quán)回調(diào)頁面包含code=就代表授權(quán)成功, 需要截取code=后面字符串
3.而且如果是授權(quán)回調(diào)頁面不需要顯示給用戶看, 返回false

4.保存
