(JavaScript) Upload String to Dropbox

Uploads a string to a file on Dropbox. This example can upload content up to 150MB, assuming a 150MB string fits in memory for your app. Larger files must be uploaded with an upload session (upload_session/start).

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.

// A Dropbox access token should have been previously obtained.
// Dropbox access tokens do not expire.
// See Dropbox Access Token.

var rest = new CkRest();

// Connect to Dropbox
success = rest.Connect("content.dropboxapi.com",443,true,true);
if (success == false) {
    console.log(rest.LastErrorText);
    return;
}

// Add request headers.
rest.AddHeader("Content-Type","application/octet-stream");
rest.AddHeader("Authorization","Bearer DROPBOX_ACCESS_TOKEN");

// The upload "parameters" contained in JSON passed in an HTTP request header.
// This is the JSON to be added in this example:
// { 
//    "path": "/jack.txt",
//    "mode": "add",
//    "autorename": true,
//    "mute": false
// }

// This will be the content of the file created in Dropbox.
var content = "All work and no play makes Jack a dull boy";

var json = new CkJsonObject();
json.AppendString("path","/jack.txt");
json.AppendString("mode","add");
json.AppendBool("autorename",true);
json.AppendBool("mute",false);
rest.AddHeader("Dropbox-API-Arg",json.Emit());

// Do the upload.  The URL is https://content.dropboxapi.com/2/files/upload.
// We already connected to content.dropboxapi.com using TLS (i.e. HTTPS),
// so now we only need to specify the path "/2/files/upload".

var responseStr = rest.FullRequestString("POST","/2/files/upload",content);
if (rest.LastMethodSuccess == false) {
    console.log(rest.LastErrorText);
    return;
}

// When successful, Dropbox responds with a 200 response code.
if (rest.ResponseStatusCode !== 200) {
    // Examine the request/response to see what happened.
    console.log("response status code = " + rest.ResponseStatusCode);
    console.log("response status text = " + rest.ResponseStatusText);
    console.log("response header: " + rest.ResponseHeader);
    console.log("response body (if any): " + responseStr);
    console.log("---");
    console.log("LastRequestStartLine: " + rest.LastRequestStartLine);
    console.log("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

console.log("LastRequestHeader: " + rest.LastRequestHeader);

// The response is JSON.
var jsonResp = new CkJsonObject();
jsonResp.EmitCompact = false;
jsonResp.Load(responseStr);

// Show the JSON response.
console.log(jsonResp.Emit());

// Returns JSON that looks like this:
// { 
//  "name": "jack.txt",
//  "path_lower": "/jack.txt",
//  "path_display": "/jack.txt",
//  "id": "id:yqx4-tE_NKAAAAAAAAAAAQ",
//  "client_modified": "2016-06-02T20:42:11Z",
//  "server_modified": "2016-06-02T20:42:11Z",
//  "rev": "8482db15f",
//  "size": 42
// }

// Sample code to get data from the JSON response:
var size = jsonResp.IntOf("size");
console.log("size = " + size);

var rev = jsonResp.StringOf("rev");
console.log("rev = " + rev);

var clientModified = jsonResp.StringOf("client_modified");
var ckdt = new CkDateTime();
ckdt.SetFromTimestamp(clientModified);
var bLocalTime = true;
var dt = new CkDtObj();
ckdt.ToDtObj(bLocalTime,dt);

console.log(dt.Day + "/" + dt.Month + "/" + dt.Year + " " + dt.Hour + ":" + dt.Minute);
