Download: Chilkat .NET Assemblies

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
Chilkat.Http http = new Chilkat.Http();

bool success;

//  Any string unlocks the component for the 1st 30 days.
success = http.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    textBox1.Text += http.LastErrorText + "\r\n";
    return;
}

//  This example duplicates the HTTP POST shown at
//  http://json.org/JSONRequest.html

//  Specifically, the request to be sent looks like this:
//  
POST /request HTTP/1.1
Accept: application/jsonrequest
Content-Encoding: identity
Content-Length: 72
Content-Type: application/jsonrequest
Host: json.penzance.org

{"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}


//  First, remove default header fields that would be automatically
//  sent.  (These headers are harmless, and shouldn't need to
//  be suppressed, but just in case...)
http.AcceptCharset = "";
http.UserAgent = "";
http.AcceptLanguage = "";
//  Suppress the Accept-Encoding header by disallowing
//  a gzip response:
http.AllowGzip = false;

//  If a Cookie needs to be added, it may be added by calling
//  AddQuickHeader:
http.AddQuickHeader("Cookie","JSESSIONID=1234");

string jsonText;
jsonText = "{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}";

//  To use SSL/TLS, simply use "https://" in the URL.

//  IMPORTANT: Make sure to change the URL, JSON text,
//  and other data items to your own values.  The URL used
//  in this example will not actually work.

Chilkat.HttpResponse resp = null;
resp = http.PostJson("http://json.penzance.org/request",jsonText);
if (resp == null ) {
    textBox1.Text += http.LastErrorText + "\r\n";
}
else {
    //  Display the JSON response.
    textBox1.Text += resp.BodyStr + "\r\n";
}
