读取来自HttpClient.GetStringAsync的响应

var client = new HttpClient();
client.Timeout = TimeSpan.FromSeconds(30); // 设置超时时间为30秒
var response = await client.GetStringAsync("https://example.com");

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;
var client = new HttpClient();
var response = await client.GetStringAsync("https://example.com");

using (var client = new HttpClient())
{
    var response = await client.GetStringAsync("https://example.com");
    // 处理响应
}

using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        using (var client = new HttpClient())
        {
            try
            {
                var response = await client.GetStringAsync("https://example.com");
                Console.WriteLine(response);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
