我正在尝试使用 .NET Core 和 C# 向我的 Vizio TV 发出 HTTPS 请求,该 API 有一些文档记录 here .
在 Chrome 中访问 HTTP 服务器时,我收到“NET::ERR_CERT_AUTHORITY_INVALID”错误。当我在 C# 中使用 HttpClient
发出请求时,将抛出 HttpRequestException
。我试过将证书添加到 Windows,但我对 TLS 还不够熟悉。
我也不担心我的通信被窥探,所以我想忽略任何 HTTPS 错误。
这是我正在使用的相关代码。
public async Task Pair(string deviceName) {
using (var httpClient = new HttpClient())
try {
httpClient.BaseAddress = new Uri($"https://{televisionIPAddress}:9000/");
// Assume all certificates are valid?
ServicePointManager.ServerCertificateValidationCallback =
(sender, certificate, chain, sslPolicyErrors) => true;
deviceID = Guid.NewGuid().ToString();
var startPairingRequest = new HttpRequestMessage(HttpMethod.Put, "/pairing/start");
startPairingRequest.Content = CreateStringContent(new PairingStartRequestBody {
DeviceID = deviceID,
DeviceName = deviceName
});
var startPairingResponse = await httpClient.SendAsync(startPairingRequest); // HttpRequestException thrown here
Console.WriteLine(startPairingResponse);
} catch (HttpRequestException e) {
Console.WriteLine(e.InnerException.Message); // prints "A security error occurred"
}
}
StringContent CreateStringContent(object obj) {
return new StringContent(JsonConvert.SerializeObject(obj), Encoding.UTF8, "application/json");
}
最佳答案
通过设置 HttpClientHandler
并将 ServerCertificateCustomValidationCallback
设置为返回 true 解决了这个问题。
using (var handler = new HttpClientHandler {
ServerCertificateCustomValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true
})
using (var httpClient = new HttpClient(handler))
关于c# - .NET 核心 HttpClient - "A security error occurred"HttpRequestException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49351595/
