//示例:
   var httpClient = new HttpClient();
    httpClient.findProxy = (url) {
      return HttpClient.findProxyFromEnvironment(url, environment: {
        "http_proxy": "192.168.3.76:8888",
        "https_proxy": "192.168.3.76:8888",
        "HTTP_PROXY": "192.168.3.76:8888",
        "HTTPS_PROXY": "192.168.3.76:8888",
      });
    };
//描述
/**
   * Function for resolving the proxy server to be used for a HTTP
   * connection from the proxy configuration specified through
   * environment variables.
   *
   * The following environment variables are taken into account:
   *
   *     http_proxy
   *     https_proxy
   *     no_proxy
   *     HTTP_PROXY
   *     HTTPS_PROXY
   *     NO_PROXY
   *
   * [:http_proxy:] and [:HTTP_PROXY:] specify the proxy server to use for
   * http:// urls. Use the format [:hostname:port:]. If no port is used a
   * default of 1080 will be used. If both are set the lower case one takes
   * precedence.
   *
   * [:https_proxy:] and [:HTTPS_PROXY:] specify the proxy server to use for
   * https:// urls. Use the format [:hostname:port:]. If no port is used a
   * default of 1080 will be used. If both are set the lower case one takes
   * precedence.
   *
   * [:no_proxy:] and [:NO_PROXY:] specify a comma separated list of
   * postfixes of hostnames for which not to use the proxy
   * server. E.g. the value "localhost,127.0.0.1" will make requests
   * to both "localhost" and "127.0.0.1" not use a proxy. If both are set
   * the lower case one takes precedence.
   *
   * To activate this way of resolving proxies assign this function to
   * the [findProxy] property on the [HttpClient].
   *
   *     HttpClient client = new HttpClient();
   *     client.findProxy = HttpClient.findProxyFromEnvironment;
   *
   * If you don't want to use the system environment you can use a
   * different one by wrapping the function.
   *
   *     HttpClient client = new HttpClient();
   *     client.findProxy = (url) {
   *       return HttpClient.findProxyFromEnvironment(
   *           url, environment: {"http_proxy": ..., "no_proxy": ...});
   *     }
   *
   * If a proxy requires authentication it is possible to configure
   * the username and password as well. Use the format
   * [:username:password@hostname:port:] to include the username and
   * password. Alternatively the API [addProxyCredentials] can be used
   * to set credentials for proxies which require authentication.
