(MFC) OneDrive -- Upload a String

See more OneDrive Examples

Uploads a string to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call, which only supports uploads up to 4MB in size. (See the other example(s) for uploading larger files.)

Note: This example requires Chilkat v9.5.0.68 or greater.

    CkString strOut;

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

    CkHttp http;

    // Use your previously obtained access token here:
    // See the following examples for getting an access token:
    //    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
    //    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
    //    Refresh Access Token (Azure AD v2.0 Endpoint).
    //    Refresh Access Token (Azure AD Endpoint).

    // (Make sure your token was obtained with the Files.ReadWrite scope.)
    http.put_AuthToken("MICROSOFT_GRAPH_ACCESS_TOKEN");

    // To upload in a single HTTP request, send a PUT request such as the following:

    // 	PUT /v1.0/me/drive/root:/{item-path}:/content
    // 	Content-type: text/plain
    // 	Content-Length: <the actual content length>
    // 
    // 	The contents of the file goes here.

    // Note: Chilkat automatically adds the Content-Length header.

    // This example will upload a string that happens to be XML.
    const char *someString = "<location><city>Chicago</city><state>IL</state></location>";
    // Upload to /someFolder/location.xml
    http.SetUrlVar("dest_path","/someFolder/location.xml");
    // If not using "me", then the path part of the URL should be /v1.0/users/{id | userPrincipalName}/...
    const char *url = "https://graph.microsoft.com/v1.0/me/drive/root:{$dest_path}:/content";

    const char *resp = http.putText(url,someString,"utf-8","application/xml",false,false);
    if (http.get_LastMethodSuccess() != true) {
        strOut.append(http.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    // If successful, a 201 status code is returned, with the driveItem object in the resp body for the newly created file.
    CkJsonObject json;
    json.put_EmitCompact(false);
    json.Load(resp);

    if (http.get_LastStatus() != 201) {

        strOut.append(json.emit());
        strOut.append("\r\n");
        strOut.append("Response status = ");
        strOut.appendInt(http.get_LastStatus());
