dart - 如何在飞镖中使用 HttpClient 发出 HTTPS 请求？

Question

我正在使用来自 dart 的 HttpClient（dart:io 包，而不是 dart:http），我想发送一个 HTTPS 请求。有没有办法做到这一点？我似乎找不到允许我这样做的方法。

Answer 1

new HttpClient().getUrl(Uri.parse('https://www.somedomain.com'));

Answer 2

发送 HTTPS 请求的步骤与 dart/flutter 中的 HTTP 相同，您必须添加的一件事是允许自签名证书处理 badCertificateCallback，将其添加到您的 HttpClient：

var httpClient = HttpClient();
      httpClient.badCertificateCallback =
          ((X509Certificate cert, String host, int port) =>
              true); // Allow self signed certificates

Answer 3

HttpClient client = new HttpClient();
client.getUrl(Uri.parse("http://www.example.com/"))
    .then((HttpClientRequest request) {
      // Optionally set up headers...
      // Optionally write to the request object...
      // Then call close.
      ...
      return request.close();
    })
    .then((HttpClientResponse response) {
      // Process the response.
      ...
    });
