如何在webapi中将查询字符串传递给POST请求

[HttpPost]
public IHttpActionResult MyMethod()
{
    // 获取查询字符串参数
    var queryString = HttpContext.Current.Request.QueryString;

    // 执行POST请求的逻辑
    // ...

    return Ok();
}

using (var client = new HttpClient())
{
    // 构建查询字符串参数
    var queryStringParams = new Dictionary<string, string>
    {
        { "param1", "value1" },
        { "param2", "value2" }
    };

    // 将查询字符串参数转换为URL编码的字符串
    var queryString = new FormUrlEncodedContent(queryStringParams).ReadAsStringAsync().Result;

    // 构建POST请求的主体
    var requestContent = new StringContent(queryString, Encoding.UTF8, "application/x-www-form-urlencoded");

    // 发送POST请求
    var response = client.PostAsync("https://example.com/api/mymethod", requestContent).Result;

    // 处理响应结果
    // ...
}
