unity 上传文件和下载资源的get post请求的写法

UnityWebRequest uwr = UnityWebRequest.Get(path);
//超时
uwr.timeout = 5;
//请求头
uwr.SetRequestHeader("", "");
yield return uwr.Send();
if (uwr.isDone && string.IsNullOrEmpty(uwr.error)){
debug.log(uwr.downloadHandler.text);
//下载图片的话
//((DownloadHandlerTexture) wwwtx.downloadHandler).texture
}

//如果有后缀文件的话，加上~跟服务器商量是否做了限制，顺序也要写对，跟服务器商量
WWWForm form = new WWWForm();
form.AddField("", "");
form.AddBinaryData("", "0.0", "0.0.jpg");
UnityWebRequest uwr = UnityWebRequest.Post(path, form);
uwr.SetRequestHeader("", "");
uwr.timeout = TIMEOUT;
yield return uwr.Send();
if (uwr.isDone && string.IsNullOrEmpty(uwr.error))
{
print(uwr.downloadHandler.text);
}
