runZoned<R> 静态方法

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

使用提供的覆盖运行 body 的新鲜 Zone。

实现

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});
}
