(C#) Upload String to Google Cloud StorageDemonstrates how to upload an in-memory string to Google Cloud Storage. Note: This example requires Chilkat v9.5.0.69 or later because it uses the http.PTextSb method.
// 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.. Chilkat.StringBuilder sbToken = new Chilkat.StringBuilder(); 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]" Chilkat.Http http = new Chilkat.Http(); http.AuthToken = sbToken.GetAsString(); // Create an XML document, and write it to a StringBuilder. // We'll be uploading this XML document. Chilkat.Xml xml = new Chilkat.Xml(); 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. Chilkat.StringBuilder sbXml = new Chilkat.StringBuilder(); 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"); string url = "https://www.googleapis.com/upload/storage/v1/b/{$bucket_name}/o?uploadType=media&name={$object_name}"; // Note: The PTextSb method first appears in Chilkat v9.5.0.69 Chilkat.HttpResponse resp = http.PTextSb("POST",url,sbXml,"utf-8","application/xml",false,false); if (http.LastMethodSuccess == false) { Debug.WriteLine(http.LastErrorText); return; } int responseCode = resp.StatusCode; if (responseCode == 401) { Debug.WriteLine(resp.BodyStr); Debug.WriteLine("If invalid credentials, then it is likely the access token expired."); Debug.WriteLine("Your app should automatically fetch a new access token and re-try."); return; } Debug.WriteLine("Response code: " + Convert.ToString(responseCode)); Debug.WriteLine("Response body"); Debug.WriteLine(resp.BodyStr); // A successful response looks like this: // Response code: 200 // Response body // { // "kind": "storage#object", // "id": "chilkat-ocean/test.xml/1502669565429870", // "selfLink": "https://www.googleapis.com/storage/v1/b/chilkat-ocean/o/test.xml", // "name": "test.xml", // "bucket": "chilkat-ocean", // "generation": "1502669565429870", // "metageneration": "1", // "contentType": "application/xml", // "timeCreated": "2017-08-14T00:12:45.379Z", // "updated": "2017-08-14T00:12:45.379Z", // "storageClass": "MULTI_REGIONAL", // "timeStorageClassUpdated": "2017-08-14T00:12:45.379Z", // "size": "181", // "md5Hash": "TCR0L7TWsw2TzOvfNvgEfA==", // "mediaLink": "https://www.googleapis.com/download/storage/v1/b/chilkat-ocean/o/test.xml?generation=1502669565429870&alt=media", // "crc32c": "ZFd5sA==", // "etag": "CO6Qpq241dUCEAE=" // } |
