runZoned<R> 静态方法

R runZoned<R>(
  1. R body(
      ),
    1. {HttpClient createHttpClient(
      1. SecurityContext?
      )?,
    2. String findProxyFromEnvironment(
      1. Uri uri,
      2. Map<String, String>? environment
      )?}
    )

    在提供的覆盖支持下，在全新的 Zone 中运行 body。

    实现方式

    static R runZoned<R>(R Function() body,
    {HttpClient Function(SecurityContext?)? createHttpClient,
    String Function(Uri uri, Map<String, String>? environment)?
        findProxyFromEnvironment}) {
  HttpOverrides overrides =
      _HttpOverridesScope(createHttpClient, findProxyFromEnvironment);
  return dart_async.runZoned<R>(body,
      zoneValues: {_httpOverridesToken: overrides});
}
