如何拆分回复文字?

在我的应用程序中,我尝试添加JWT安全性。在响应文本中,我添加了用户和用户名的权限。全部工作,但如果我尝试拆分响应文本,它不起作用。

login(username: string, password: string): Observable<boolean> {
    return this.http.post(AUTH_USER_PATH, JSON.stringify({username: username, password: password}),
        this.getPlainRequestOptions())
        .map((response: Response) => {


            let token: string = response.headers.get('Authorization').slice(7); //working
            let authorities: string[] = JSON.parse(response.text().split('|')[0]); //not working
            let username: string = JSON.parse(response.text().split('|')[1]); //not working


            console.log(authorities);
            console.log(username);
            if (token) {
                localStorage.setItem('token', JSON.stringify(token));
                localStorage.setItem('authorities', response.text());
                localStorage.setItem('username', response.text());
                return true;
            } else {
                return false;
            }
        })
        .catch((error: any) => Observable.throw(error));
}

如果我不使用拆分,那么在控制台中我看到:

[ROLE_USER, ROLE_ADMIN]|user1

如何轻松拆分此字符串(数组)以获得此结果?

authorities = [ROLE_USER, ROLE_ADMIN];
username = "user1";

|在正则表达式中,字符是一个特殊字符。 尝试使用\

转义特殊字符

let authorities:string [] = JSON.parse(response.text()。split(&#39; \ |&#39;)[0]);

这是一个应该有用的链接What special characters must be escaped in regular expressions?
