前端请求后端接口没问题，但是装了 pdfjs-dist 组件后，请求后端 pdf 地址提示跨域问题？ 通过各种搜索，我在后端加了 header 允许的域名，但是提示 Access to XMLHttpRequest at '' from origin '' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values ', *', but only one is allowed. 请问怎么解决呀

Access-Control-Allow-Origin 制定 IP 或域名，不要用 *。或者去掉"Access-Control-Allow-Credentials", "true"。
