(Swift 3,4,5...) 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 v9.5.0.97 or greater.

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

    // This example uses the OAuth client credentials flow.
    // See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

    // Use your client ID, client secret, and tenant ID in the following lines
    let json = CkoJsonObject()!
    json.update("client_id", value: "2871da2c-8176-4b7f-869b-2311aa82e743")
    json.update("client_secret", value: "2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH")
    json.update("scope", value: "https://graph.microsoft.com/.default")
    json.update("token_endpoint", value: "https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token")

    let http = CkoHttp()!
    http.authToken = json.emit()

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

    // 	PUT /v1.0/users/{user_id}/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.
    var someString: String? = "<location><city>Chicago</city><state>IL</state></location>"

    // Upload to /TestDir/location.xml
    http.setUrlVar("dest_path", value: "/TestDir/location.xml")
    http.setUrlVar("user_id", value: "4fe732c3-322e-4a6b-b729-2fd1eb5c6104")
    var url: String? = "https://graph.microsoft.com/v1.0/users/{$user_id}/drive/root:{$dest_path}:/content"

    var resp: String? = http.putText(url, textData: someString, charset: "utf-8", contentType: "application/xml", md5: false, gzip: false)
    if http.lastMethodSuccess != true {
        print("\(http.lastErrorText!)")
        return
    }

    // If successful, a 201 status code is returned, with the driveItem object in the resp body for the newly created file.
    json.emitCompact = false
    json.load(resp)

    if http.lastStatus.intValue != 201 {

        print("\(json.emit()!)")
        print("Response status = \(http.lastStatus.intValue)")
        return
    }

    // Success.  Examine the driveItem JSON object:
    print("\(json.emit()!)")
    print("-- Success --")
