HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. C#

bool success = false;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

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

//  Specifiy a session log file so we can see the exact request/response
http.SessionLogFilename = "c:/aaworkarea/sessionLog.txt";

//  Perhaps add a custom header or two..
http.SetRequestHeader("x-exz-date","20201012T235046Z");
http.SetRequestHeader("x-exz-id","1234");

//  Send a GET request to https://www.example.com/someting?param1=123&param2=abc
string url = "https://www.example.com/someting?param1=123&param2=abc";
Chilkat.HttpResponse resp = new Chilkat.HttpResponse();
success = http.HttpNoBody("GET",url,resp);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

//  The GET request that is sent looks like this.
//  The Accept and Accept-Encoding headers are automatically added by default.

//  	GET /someting?param1=123&param2=abc HTTP/1.1
//  	Host: www.example.com
//  	Accept: */*
//  	Accept-Encoding: gzip
//  	x-exz-date: 20201012T235046Z
//  	x-exz-id: 1234

//  Get the response status
int statusCode = resp.StatusCode;
Debug.WriteLine("Response status: " + Convert.ToString(statusCode));

//  Get the response body
Debug.WriteLine(resp.BodyStr);

//  -------------------------------------------------------------
//  Let's say we want to send a DELETE request, and we only want to accept an application/json response,
//  and we don't want gzipped responses...

//  First remove the previously specified custom headers.
http.ClearHeaders();

//  Indicate we only accept application/json non-gzipped responses.
http.Accept = "application/json";
http.AllowGzip = false;

//  Send a DELETE request to https://www.example.com/deleteSomething
url = "https://www.example.com/deleteSomething";
success = http.HttpNoBody("DELETE",url,resp);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

//  The DELETE request that is sent looks like this.
//  The empty Accept-Encoding header value means we only want non-compressed responses.

//  	DELETE /deleteSomething HTTP/1.1
//  	Host: www.example.com
//  	Accept: application/json
//  	Accept-Encoding: 

//  Get the response status
statusCode = resp.StatusCode;
Debug.WriteLine("Response status: " + Convert.ToString(statusCode));

//  Get the response body
Debug.WriteLine(resp.BodyStr);
