使用Spring Boot基本身份验证的Angular 6无法正常工作

Question

由于我遵循6号角代码，因此出现401错误

var headers_object = new HttpHeaders();
headers_object.append('Accept', 'application/json');
headers_object.append('Content-Type', 'application/json');
headers_object.append('Authorization', 'Basic YWRtaW4xOnNlY3JldDE=');

const httpOptions = {
  headers: headers_object
};

我正在这样调用Spring Boot服务

return this.http.get('http://localhost:8080/pocapp/courses', httpOptions);

在Spring Boot应用程序中获取以下日志
