Cross-Origin Read Blocking (CORB) 阻止跨源

Error:

请求的资源上不存在“Access-Control-Allow-Origin”标头。起源 'https://abcd.com https://abcd.com' 因此不允许访问。响应的 HTTP 状态代码为 403。

每当我尝试从 Angular 4 发出 http post 请求时，我都会收到上述错误。我正在 JSON 正文中发送中文字符并且已经允许

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Accept,x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN,Cache-Control,Content-Type,Keep-Alive,Origin,User-Agent,X-Requested-With,charset=utf-8");

每次发中文的时候都会遇到这个问题。

Access-Control-Allow-Headers 可能会导致问题 - 尝试使用值 * 的 Access-Control-Allow-Headers
