   "/api/*": {
      "target": "https://localhost:8000",
      "secure": false,
      "logLevel": "debug",
      "pathRewrite": {
        "^/api": ""
      },
      "changeOrigin": true
    }

1. "api/*":
   您的应用程序中对/api/的所有请求都将转发到 target": "https://localhost:8000/api

2. "secure": false,:
   在HTTPS上运行的后端服务器，带有 默认情况下，无效证书将不被接受.如果你想， 您需要设置secure: false.
   

1. "api/*":
   All requests made to /api/ from within your application will be forwarded to target": "https://localhost:8000/api

2. "secure": false,:

"logLevel": "debug"
帮助调试您的代理是否 工作正常，您还可以将logLevel选项添加为 如下:logLevel的可能选项包括debug，info， warn，error和silent(默认为info).

"logLevel": "debug"
To help debug whether or not your proxy is working properly, you can also add the logLevel option as follows: Possible options for logLevel include debug, info, warn, error, and silent (default is info).

"pathRewrite": { "^/api": "" }, pathRewrite设置指出，如果路径匹配^/api(即，它以/api开头)，则用空字符串重写该部分(即，将其从路径中删除)，因此所有对https://localhost:8000/api的请求都将转到

"pathRewrite": { "^/api": "" }, pathRewrite setting says that if the path matches ^/api (i.e. if it starts with /api) then rewrite that portion with the empty string (i.e. remove it from the path), so all the request to https://localhost:8000/api will go to https://localhost:8000

"changeOrigin": true:如果您需要访问不在本地主机上的后端，或者在后端上使用某些虚拟代理(例如使用Apache2配置的虚拟代理)时，请将其设置为true.

"changeOrigin": true: If you need to access a backend that is not on localhost or when you’re using some virtual proxies (such as configured with Apache2) on your backend set it to true.

代理支持可以帮助您摆脱某些 CORS 在开发阶段出现异常，但客户端应用程序无法处理这些异常.必须将服务器配置为接受应用程序的请求.

注意:proxy配置用于通过ng serve运行开发服务器时代理调用.运行ng build后，您将负责Web服务器及其配置.

NOTE: The proxy configuration is intended to proxy calls when running the dev server via ng serve. After you run ng build you are responsible for the web server and its configurations.
