Uploading raw data to an HTTP server (PUT)

Some modern web applications prefer that files be uploaded via the HTTP PUT verb. For this scenario, Unity provides the UnityWebRequest.PUT function.

This function takes two arguments. The first argument is a string and specifies the target URL for the request. The second argument may be either a string or a byte array, and specifies the payload data to be sent to the server.

Function signatures:

WebRequest.Put(string url, string data);
WebRequest.Put(string url, byte[] data);

Детали

• This function creates a UnityWebRequest and sets the content type to application/octet-stream.
• This function attaches a standard DownloadHandlerBuffer to the UnityWebRequest. As with the POST functions, you can use this to return result data from your applications.
• This function stores the input upload data in a standard UploadHandlerRaw object and attaches it to the UnityWebRequest. As a result, if using the byte[] function, changes made to the byte array performed after the UnityWebRequest.PUT call are not reflected in the data uploaded to the server.

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;
 
public class MyBehavior : MonoBehaviour {
    void Start() {
        StartCoroutine(Upload());
    }
 
    IEnumerator Upload() {
        byte[] myData = System.Text.Encoding.UTF8.GetBytes("This is some test data");
        UnityWebRequest www = UnityWebRequest.Put("http://www.my-server.com/upload", myData);
        yield return www.SendWebRequest();
 
        if (www.result != UnityWebRequest.Result.Success) {
            Debug.Log(www.error);
        }
        else {
            Debug.Log("Upload complete!");
        }
    }
}
