(JavaScript) REST URL Encode Path Parts and Query Params

See more REST Examples

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

// This example demonstrates how to URL encode the path passed to a REST function.
// It is demonstrated with an Amazon SP API GET request to get details about a listings item for a selling partner.
// See https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#getlistingsitem

var rest = new CkRest();

// Connect to the REST server.
var bTls = true;
var port = 443;
var bAutoReconnect = true;
success = rest.Connect("sellingpartnerapi-eu.amazon.com",port,bTls,bAutoReconnect);

rest.ClearAllQueryParams();
rest.AddQueryParam("marketplaceids","XYZABC123");
rest.AddQueryParam("includedData","offers");

rest.AddHeader("x-amz-access-token","YOUR_ACCESS_TOKEN");

var authAws = new CkAuthAws();
authAws.AccessKey = "YOUR_AWS_APP_ID";
authAws.SecretKey = "YOUR_AWS_APP_SECRET_KEY";
authAws.Region = "eu-west-1";
authAws.ServiceName = "execute-api";
rest.SetAuthAws(authAws);

// The path that is passed to FullRequestNobBody

// Here's a sample path that is not yet URL encoded.
var path = "/listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS(BOXED)";

// The path passed to FullRequestNoBody needs to have the parts URL-encoded.
// The "/" chars are not URL encoded, but the individual path parts should be URL encoded.
// For example:  /listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS%28BOXED%29

// In this case, we'll prepare the path like this:
var sbPath = new CkStringBuilder();
sbPath.Append("100x100_28g_LANCETS(BOXED)");
// URL encode the contents of the sbPath.
sbPath.Encode("url","utf-8");
// Prepend the remaining which does not need to be URL encoded.
sbPath.Prepend("/listings/2022-07-01/items/ABCDEFGHIJ/");

console.log("URL encoded path: " + sbPath.GetAsString());

var responseJson = rest.FullRequestNoBody("GET",sbPath.GetAsString());
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

console.log(responseJson);
console.log("----");
