public static Networking.UnityWebRequest Put(string uri, byte[] bodyData);


public static Networking.UnityWebRequest Put(string uri, string bodyData);


uri The URI to which the data will be sent.
bodyData The data to transmit to the remote server.

If a string, the string will be converted to raw bytes via System.Text.Encoding.UTF8.


UnityWebRequest A UnityWebRequest configured to transmit bodyData to uri via HTTP PUT.


Creates a UnityWebRequest configured to upload raw data to a remote server via HTTP PUT.

This method creates a UnityWebRequest, sets the target URL to the string uri argument and the method to PUT. It also sets the Content-Type header to application/octet-stream.

This method attaches a standard DownloadHandlerBuffer to the UnityWebRequest. This is for convenience during development, as well as for applications which return status information regarding the uploaded data in the HTTP response body.

This method stores the input upload data in an UploadHandlerRaw object and attaches it to the UnityWebRequest. UploadHandlerRaw copies the input data into a buffer. Therefore, changes to the bodyData array performed after the call to this method will not be reflected in the data sent to the server.

public class MyBehavior : MonoBehaviour { void Start() { StartCoroutine(Upload()); }

IEnumerator Upload() { byte[] myData = System.Text.Encoding.UTF8.GetBytes("This is some test data"); using (UnityWebRequest www = UnityWebRequest.Put("", myData)) { yield return www.SendWebRequest();

if (www.result != UnityWebRequest.Result.Success) { Debug.Log(www.error); } else { Debug.Log("Upload complete!"); } } } }
