JS cross-domain code snippet_javascript skills

The following code block is a proxy for js to call a general handler to implement js cross-domain. If js needs to cross domains multiple times, the following method is recommended.

Copy code The code is as follows:

public string GetInfo(HttpContext context)
{
string post = "a=XX&b=XX";
return CreateHttpRequest("https://www.XXXX.com", post, "POST");
}


#region Construct request
///

/// Construct request
///

/// Request Address
/// Request Parameters
/// Request Method
///
public string CreateHttpRequest(string requestUrl, string requestParam, string requestMethod)
{
try
{
System.Net.HttpWebRequest request = System.Net.HttpWebRequest.Create(requestUrl) as System.Net.HttpWebRequest;
request.Method = requestMethod;
string post = requestParam;

byte [] bytes = System.Text.Encoding.UTF8.GetBytes(post);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;
System.IO.Stream stream = request.GetRequestStream();
stream.Write(bytes, 0, bytes.Length);
System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse ;
System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream(), System.Text.Encoding.UTF8);
return sr.ReadToEnd();
}
catch (Exception)
{
return "";
}

}
