Unity Ftp、Http下载资源的简例

 Http下载文件:

using System;
using System.ComponentModel;
using System.Net;
using UnityEngine;

public class TestDownloadBehaviour_http : MonoBehaviour
{
    public string RemoteFileURI;
    public string SaveFilePath;

    // Start is called before the first frame update
    void Start()
    {
        DownloadFile();
    }

    // Update is called once per frame
    void DownloadFile()
    {
        using (WebClient wc = new WebClient())
        {
            try
            {
                wc.Proxy = null;
                Uri address = new Uri(RemoteFileURI);
                //调用DownloadFile方法下载文件
                // wc.DownloadFile(textBox1.Text.ToString(), textBox2.Text.ToString());

                //调用DownloadFileAsync异步下载文件
                wc.DownloadFileAsync(address, Application.dataPath + "/" + SaveFilePath);

                wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(OnDownloadProgessChanged);
                //下载完成的响应事件
                wc.DownloadFileCompleted += new AsyncCompletedEventHandler(OnDownloadFileComplited);
            }
            catch (Exception ex)
            {
                Debug.LogError(ex.Message);
            }
        }

    }

    void OnDownloadProgessChanged(object sender, DownloadProgressChangedEventArgs e)
    {
        Debug.LogFormat("progress = {0}, total = {1}, received = {2}", e.ProgressPercentage, e.TotalBytesToReceive, e.BytesReceived);
    }

    void OnDownloadFileComplited(object sender, AsyncCompletedEventArgs e)
    {
        Debug.LogFormat("下载完成");
    }
}

FTP下载文件：

using System;
using System.ComponentModel;
using System.Net;
using UnityEngine;

public class TestDownloadBehaviour : MonoBehaviour
{
    public string RemoteFileURI;
    public string SaveFilePath;

    long _FileSize; // FTP下载时，无法获取到整个文件Size。所以提前调用WEB API来获取Size，然后进行下载。

    // Start is called before the first frame update
    void Start()
    {
        DownloadFile();
    }

    // Update is called once per frame
    void DownloadFile()
    {
        FtpWebRequest f = WebRequest.Create(RemoteFileURI) as FtpWebRequest;
        f.Method = WebRequestMethods.Ftp.GetFileSize;
        FtpWebResponse fr = f.GetResponse() as FtpWebResponse;
        _FileSize = fr.ContentLength;
        fr.Close();

        using (WebClient wc = new WebClient())
        {
            try
            {
                wc.Proxy = null;
                Uri address = new Uri(RemoteFileURI);
                //调用DownloadFile方法下载文件
                // wc.DownloadFile(textBox1.Text.ToString(), textBox2.Text.ToString());
                
                //调用DownloadFileAsync异步下载文件
                wc.DownloadFileAsync(address, Application.dataPath + "/" + SaveFilePath);

                wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(OnDownloadProgessChanged);
                //下载完成的响应事件
                wc.DownloadFileCompleted += new AsyncCompletedEventHandler(OnDownloadFileComplited);

            }
            catch (Exception ex)
            {
                Debug.LogError(ex.Message);
            }
        }

    }

    void OnDownloadProgessChanged(object sender, DownloadProgressChangedEventArgs e)
    {
        Debug.LogFormat("progress = {0}, total = {1}, received = {2}", (float)e.BytesReceived / _FileSize, _FileSize, e.BytesReceived);
    }

    void OnDownloadFileComplited(object sender, AsyncCompletedEventArgs e)
    {
        Debug.LogFormat("下载完成");
    }
}
