Javascript 将WebMethod值传递到.aspx页面

项目1:（我从这里发送成员代码“10002”），点击按钮

protected void lnkRFQ_Click(object sender, EventArgs e)
{
    dynamic strReturn = null;
    var _input = new { CLIENT_ID = txtMember.Text != null ? txtMember.Text : "", };
    var result = new { input = _input };

    string inputJson = (new JavaScriptSerializer()).Serialize(result);
    HttpContent inputContent = new StringContent(inputJson, Encoding.UTF8,"application/json");
    HttpResponseMessage response = client.PostAsync("http://localhost:52211/test.aspx/SetSession", inputContent).Result;

    if (response.IsSuccessStatusCode)
    { strReturn = response.Content.ReadAsStringAsync().Result; }
    else
    { string result1 = ("Product" + response.Content.ReadAsStringAsync().Result); }    
}

项目2:（我收到的是Web方法中的成员代码“10002”）并存储在会话中

[WebMethod(EnableSession = true)]
public static dynamic SetSession(dynamic input) 
{   
    var MemberCode = input["CLIENT_ID"]; Page objp = new Page();
    objp.Session["strDwnPath"] = MemberCode;
    string sessinp = objp.Session["strDwnPath"].ToString();
    return input;
}

我的问题是，在我接收到这里之后，如何在JavaScript函数中传递这个会话或值
