(JavaScript) ETrade OAuth1 Authorization (3-legged) Step 1

Demonstrates the first step in 3-legged OAuth1 authorization for the ETrade REST API. This example sends an HTTP request to the "request token URL" to get a request token that begins the OAuth1 process. (See https://apisb.etrade.com/docs/api/authorization/request_token.html )

This example uses the sandbox request token URL. The live request token URL would be "https://api.etrade.com/oauth/request_token".

Note: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var consumerKey = "ETRADE_CONSUMER_KEY";
var consumerSecret = "ETRADE_CONSUMER_SECRET";

// Note: This example uses the sandbox request token URL.
// The live Get Request Token Request URL is:
// https://api.etrade.com/oauth/request_token
// This example will use the Sandbox Token Request URL:
var requestTokenUrl = "https://apisb.etrade.com/oauth/request_token";

var http = new CkHttp();
success = true;

http.OAuth1 = true;
http.OAuthConsumerKey = consumerKey;
http.OAuthConsumerSecret = consumerSecret;
http.OAuthCallback = "oob";

var resp = new CkHttpResponse();
success = http.HttpNoBody("GET",requestTokenUrl,resp);
if (success == false) {
    console.log(http.LastErrorText);
    return;
}

// If successful, the resp.BodyStr contains something like this:  
// oauth_token=-Wa_KwAAAAAAxfEPAAABV8Qar4Q&oauth_token_secret=OfHY4tZBX2HK4f7yIw76WYdvnl99MVGB&oauth_callback_confirmed=true
console.log(resp.BodyStr);

var hashTab = new CkHashtable();
hashTab.AddQueryParams(resp.BodyStr);

var requestToken = hashTab.LookupStr("oauth_token");
var requestTokenSecret = hashTab.LookupStr("oauth_token_secret");
http.OAuthTokenSecret = requestTokenSecret;

console.log("oauth_token = " + requestToken);
console.log("oauth_token_secret = " + requestTokenSecret);

// Save this request token for the next step..
var json = new CkJsonObject();
json.AppendString("oauth_token",requestToken);
json.AppendString("oauth_token_secret",requestTokenSecret);

var fac = new CkFileAccess();
fac.WriteEntireTextFile("qa_data/tokens/etrade_request_token.json",json.Emit(),"utf-8",false);

// ---------------------------------------------------------------------------

// The next step is to form a URL to send to the authorizeUrl
// This is an HTTP GET that we load into a popup browser.
var authorizeUrl = "https://us.etrade.com/e/t/etws/authorize";

var sbUrlForBrowser = new CkStringBuilder();
sbUrlForBrowser.Append(authorizeUrl);
sbUrlForBrowser.Append("?key=");
sbUrlForBrowser.Append(consumerKey);
sbUrlForBrowser.Append("&token=");
sbUrlForBrowser.Append(requestToken);
var url = sbUrlForBrowser.GetAsString();

// Launch the system's default browser navigated to the URL.
var oauth2 = new CkOAuth2();
success = oauth2.LaunchBrowser(url);
if (success == false) {
    console.log(oauth2.LastErrorText);
    return;
}

// The ETrade account owner will login and grant access to the application.
// A short verifier code will be displayed (as shown below), and this must be copy-and-pasted
// into the next step to Complete the 3-legged OAuth1 Authorization 

// Note: The browser will NOT automatically direct you to the next page.
// You should copy the verifier code, close the browser, and then paste the verifier
// code into your application.
