一些现代 Web 应用程序更喜欢通过 HTTP PUT 动词上传文件。针对这种情况,Unity 提供了 UnityWebRequest.PUT 函数。
此函数采用两个参数。第一个参数是一个字符串,用于指定请求的目标 URL。第二个参数是字符串或字节数组,用于指定要发送到服务器的有效负载数据。
函数签名:
WebRequest.Put(string url, string data);
WebRequest.Put(string url, byte[] data);
UnityWebRequest 并将内容类型设置为 application/octet-stream。DownloadHandlerBuffer 附加到 UnityWebRequest。与 POST 函数一样,此函数可用于从应用程序返回结果数据。UploadHandlerRaw 对象中,然后将此对象附加到 UnityWebRequest。因此,如果使用 byte[] 函数,则在 UnityWebRequest.PUT 调用之后对字节数组执行的更改不会反映在上传到服务器的数据中。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("https://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!");
        }
    }
}
