我正在尝试Sign Up实现Constant Contact. 他们给了我这个 HTML 代码。如果我将其保存为 HTML 页面,则可以正常运行。

我想要做的是将此表单转换为将执行 onClick 按钮的 C# 代码。HTML 部分看起来不错,但今天是我使用 ASP.net 的第一天,我不知道要在代码隐藏 .cs 文件中放入什么代码。搜索了很多,非常困惑。

单击提交按钮时会单击此方法:

protected void buttonId_Click(object sender, EventArgs e)
{

}

这是我的ui端代码:

<asp:TextBox ID="TextBox3" runat="server" class="name" value="First Name" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'First Name';}"></asp:TextBox>
<asp:TextBox ID="TextBox4" runat="server" class="name" value="Last Name" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Last Name';}"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server" class="name" value="Join our mailing list" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Join our mailing list';}"></asp:TextBox><br>

<asp:Button id="buttonId" OnClick="buttonId_Click" class="btn btn-info sub1" runat="server" Text="SUBSCRIBE">

</asp:Button>

这是我从不断联系中获得的 HTML 代码:

<form data-id="embedded_signup:form" class="ctct-custom-form Form" name="embedded_signup" method="POST" action="https://visitor2.constantcontact.com/api/signup">
   <p>Sign up to get interesting news and updates delivered to your inbox.</p>
   <!-- The following code must be included to ensure your sign-up form works properly. -->
   <input data-id="ca:input" type="hidden" name="ca" value="my-secrect-key">
   <input data-id="list:input" type="hidden" name="list" value="3">
   <input data-id="source:input" type="hidden" name="source" value="EFD">
   <input data-id="required:input" type="hidden" name="required" value="list,email">
   <input data-id="url:input" type="hidden" name="url" value="">
   <p data-id="Email Address:p" ><input data-id="Email Address:input" type="text" name="email" value="" maxlength="80"></p>
   <p data-id="First Name:p" ><input data-id="First Name:input" type="text" name="first_name" value="" maxlength="50"></p>
   <p data-id="Last Name:p" ><input data-id="Last Name:input" type="text" name="last_name" value="" maxlength="50"></p>
   <button type="submit" class="Button ctct-button Button--block Button-secondary" data-enabled="enabled">Sign Up</button>
</form>

这是您可以在按钮 OnClick 事件中放入的一些代码示例。此 POST 的数据到另一个 URL。

希望你能弄清楚这段代码发生了什么。基本上,它使用来自 HTML 表单的所有数据构建一个字符串(数据),并使用 HTTP POST 将其提交到其他网站。

您很可能还需要检查来自其他网站的回复。

string remoteUrl = "https://visitor2.constantcontact.com/api/signup";

ASCIIEncoding encoding = new ASCIIEncoding();
string data = "ca=my-secrect-key&list=3&source=EFD&required=list,email&url=&email=" + Server.UrlEncode(TextBox1.Text) + "&first_name=" + Server.UrlEncode(TextBox2.Text) + "&last_name=" + Server.UrlEncode(TextBox3.Text);
byte[] bytes = encoding.GetBytes(data);
HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create(remoteUrl);
httpRequest.Method = "POST";
httpRequest.ContentType = "application/x-www-form-urlencoded";
httpRequest.ContentLength = bytes.Length;
using (Stream stream = httpRequest.GetRequestStream())
{
    stream.Write(bytes, 0, bytes.Length);
    stream.Close();
}
