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!");
}
}
}
