Rust Requires Chilkat v11.0.0+

Example: Http.HttpJson method - Send a POST with JSON Body

See more HTTP Examples

Demonstrates how to call the HttpJson method, which sends an HTTP POST with a JSON body. This example sends the following request:

POST /echo_request_body.asp HTTP/1.1
Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

Rust

let http = chilkat::Http::new();
let _ = false;

let json = chilkat::JsonObject::new();

// Build the following JSON:  {"greeting":"Hello World"}
let _ = json.update_string("greeting", "Hello World");

// This URL echoes the contents of the request body, letting us view it.
let url = "https://chilkatsoft.com/echo_request_body.asp".to_string();

// Send a POST with the JSON in the HTTP request body.
let resp = chilkat::HttpResponse::new();
if http.http_json("POST", &url, &json, "application/json", &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

println!("Response Status Code: {}", resp.status_code());

// Examine the request we sent.
// The LastHeader property stores the HTTP request header of the most recent request sent,
// and in this instance, the response body mirrors the request body.
println!("{}", http.last_header());
println!("{}", resp.body_str());

// Output:

// POST /echo_request_body.asp HTTP/1.1
// Host: chilkatsoft.com
// Accept: */*
// Accept-Encoding: gzip
// Content-Type: application/json
// Content-Length: 26
// 
// {"greeting":"Hello World"}
