Question

我正在使用来自dart的HttpClient（dart：io package，not dart：http），我想发送一个HTTPS请求。有没有办法做到这一点？我似乎无法找到一种能让我这样做的方法。

Answer 1

我想向您推荐dio包，dio是Dart / Flutter的强大Http客户端，它支持拦截器，FormData，请求取消，文件下载，超时等。

dio非常易于使用：

执行POST请求：

response=await dio.post("/test",data:{"id":12,"name":"wendu"})

发送FormData：

FormData formData = new FormData.from({
   "name": "wendux",
   "age": 25,
});
response = await dio.post("/info", data: formData)

更多详情请参阅Github中的dio：https://github.com/flutterchina/dio。

Answer 2

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

Answer 3

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，并将其添加到HttpClient中：

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

Answer 4

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.
      ...
    });
