Google Contacts - Adding/Updating a photo for a contact

See more Google APIs Examples

Demonstrates how to upload a photo for a Google Contact. Rust

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

// --------------------------------------------------------------------------------------------------------
// Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
// Once connected, the REST object may be re-used for many REST API calls.
// (It's a good idea to put the connection setup code in a separate function/subroutine.)
// --------------------------------------------------------------------------------------------------------

// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file 
// saved by this example: Get Google Contacts OAuth2 Access Token

let json_token = chilkat::JsonObject::new();
if json_token.load_file("qa_data/tokens/googleContacts.json").is_err() {
    println!("Failed to load googleContacts.json");
    return;
}

let g_auth = chilkat::AuthGoogle::new();
g_auth.set_access_token(&json_token.string_of("access_token").unwrap_or_default());

let rest = chilkat::Rest::new();

// Connect using TLS.
let b_auto_reconnect = true;
let _ = rest.connect("www.google.com", 443, true, b_auto_reconnect).is_ok();

// Provide the authentication credentials (i.e. the access token)
let _ = rest.set_auth_google(&g_auth);

// ----------------------------------------------
// OK, the REST connection setup is completed..
// ----------------------------------------------

// To upload a photo for the contact, send the following:

// 	PUT /m8/feeds/photos/media/default/contactId
// 	If-match: Etag
// 	Content-Type: image/*
// 	...
// 	[Photo data bytes]

let _ = rest.add_header("GData-Version", "3.0");
let _ = rest.add_header("If-Match", "*");
let _ = rest.add_header("Content-Type", "image/*");

let sb_path = chilkat::StringBuilder::new();
let _ = sb_path.append("/m8/feeds/photos/media/default/{contactId}");
// Upload a photo for the contact having contactId = "1ea2e4fe0ef24e09"
let num_replacements = sb_path.replace("{contactId}", "1ea2e4fe0ef24e09");

// Let's get our photo data..
let png_data = chilkat::BinData::new();
let _ = png_data.load_file("qa_data/png/dude.png").is_ok();

let sb_response_body = chilkat::StringBuilder::new();
if rest.full_request_bd("PUT", &sb_path.get_as_string().unwrap_or_default(), &png_data, &sb_response_body).is_err() {
    println!("{}", rest.last_error_text());
    return;
}

// A successful response will have a status code equal to 200.
if rest.response_status_code() != 200 {
    println!("response status code = {}", rest.response_status_code());
    println!("response status text = {}", rest.response_status_text());
    println!("response header: {}", rest.response_header());
    println!("response body: {}", sb_response_body.get_as_string().unwrap_or_default());
    return;
}

// If the 200 success response was received.
println!("Response Body:");
println!("{}", sb_response_body.get_as_string().unwrap_or_default());
println!("Success.");
