C# 发送带cookie的http请求_C#发送请求带cookie

一、Get请求带cookie

发送带cookie的请求，最好带上浏览器代理字符串：

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.88 Safari/537.36

/// 

/// get请求,带cookie
/// 
/// 
/// 
public static async Task GetAsync(string url, string cookie)
{
    HttpClient client = new HttpClient();
    if (string.IsNullOrEmpty(cookie) == false)
    {
        client.DefaultRequestHeaders.Add("cookie", cookie);
    }
    //指定浏览器代理
    client.DefaultRequestHeaders.Add("user-agent", UserAgent);
    HttpResponseMessage resp = await client.GetAsync(url);
    //获取请求内容
    HttpContent respContent = resp.Content;
    return await respContent.ReadAsStringAsync();
}

二、Post请求带cookie

/// 

/// Post 请求，无参(注：默认使用UTF8编码)
/// 
/// 
/// 
public static async Task PostAsync(string url, string content, string cookie)
{
    HttpClient client = new HttpClient();
    if (string.IsNullOrEmpty(cookie) == false)
    {
        client.DefaultRequestHeaders.Add("cookie", cookie);
    }
    //指定浏览器代理
    client.DefaultRequestHeaders.Add("user-agent", UserAgent);
    using (MemoryStream ms = new MemoryStream())
    {
        byte[] bytes = Encoding.UTF8.GetBytes(content);
        ms.Write(bytes, 0, bytes.Length);
        ms.Seek(0, SeekOrigin.Begin);//设置指针读取位置，否则发送无效
        HttpContent hc = new StreamContent(ms);
        HttpResponseMessage resp = await client.PostAsync(url, hc);
        return await resp.Content.ReadAsStringAsync();
    }
}
