(JavaScript) Upload String to Google Cloud Storage
Demonstrates how to upload an in-memory string to Google Cloud Storage. Note: This example requires Chilkat v11.0.0 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 uses a previously obtained access token having permission for the
// scope "https://www.googleapis.com/auth/cloud-platform"
// In this example, Get Google Cloud Storage OAuth2 Access Token,
// the service account access token was saved to a text file. This example fetches the access token from the file..
var sbToken = new CkStringBuilder();
sbToken.LoadFile("qa_data/tokens/googleCloudStorageAccessToken.txt","utf-8");
// Send a POST equivalent to this curl command.
// The content of the file is contained in the request body.
// curl -X POST --data-binary @[OBJECT] \
// -H "Authorization: Bearer [OAUTH2_TOKEN]" \
// -H "Content-Type: [OBJECT_CONTENT_TYPE]" \
// "https://www.googleapis.com/upload/storage/v1/b/[BUCKET_NAME]/o?uploadType=media&name=[OBJECT_NAME]"
var http = new CkHttp();
http.AuthToken = sbToken.GetAsString();
// Create an XML document, and write it to a StringBuilder.
// We'll be uploading this XML document.
var xml = new CkXml();
xml.Tag = "note";
xml.UpdateChildContent("to","Tove");
xml.UpdateChildContent("from","Jani");
xml.UpdateChildContent("heading","Reminder");
xml.UpdateChildContent("body","Don't forget me this weekend!");
// Write the XML to sbXml.
var sbXml = new CkStringBuilder();
xml.GetXmlSb(sbXml);
// sbXml contains this:
// <note>
// <to>Tove</to>
// <from>Jani</from>
// <heading>Reminder</heading>
// <body>Don't forget me this weekend!</body>
// </note>
// Construct a URL to upload to an object named "test.xml" in the "chilkat-ocean" bucket.
http.SetUrlVar("bucket_name","chilkat-ocean");
http.SetUrlVar("object_name","test.xml");
var url = "https://www.googleapis.com/upload/storage/v1/b/{$bucket_name}/o?uploadType=media&name={$object_name}";
var resp = new CkHttpResponse();
success = http.HttpSb("POST",url,sbXml,"utf-8","application/xml",resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
var responseCode = resp.StatusCode;
if (responseCode == 401) {
console.log(resp.BodyStr);
console.log("If invalid credentials, then it is likely the access token expired.");
console.log("Your app should automatically fetch a new access token and re-try.");
return;
}
console.log("Response code: " + responseCode);
console.log("Response body");
console.log(resp.BodyStr);
// A successful response looks like this:
// Response code: 200
// Response body
