問題描述

我使用以下代碼從 FTP 站點(diǎn)獲取文件.它可以在我的計(jì)算機(jī)上運(yùn)行，??但是當(dāng)我在另一臺計(jì)算機(jī)上運(yùn)行它時(shí)它只會(huì)返回 HTML 代碼(當(dāng)我通過瀏覽器訪問 FTP 時(shí)，我可以看到 HTML 是網(wǎng)頁的代碼).怎么了?

I use below codes to get files from a FTP site. It works in my computer, but it only return HTML codes when I run it on another computer (I can see that the HTML are codes of web page when I access FTP via browser). What's wrong?

public String GetFilesAsString(string folder,string fileExtension)
{
    StringBuilder result = new StringBuilder();
    FtpWebRequest reqFTP;
    try
    {
        String ftpserver = ftp + folder+"/";

        reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpserver));
        reqFTP.UsePassive = false;
        reqFTP.UseBinary = true;
        reqFTP.Credentials = new NetworkCredential(username, password);
        reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
        FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();

        StreamReader reader = new StreamReader(response.GetResponseStream(), System.Text.Encoding.UTF8);
        string line = "";

        while (reader.Peek()>-1)
        {
            line = reader.ReadLine();
            Console.WriteLine(line);//**********HTML was wrote out here*************
        }

        if (result.ToString().LastIndexOf('
') >= 0)
            result.Remove(result.ToString().LastIndexOf('
'), 1);
        reader.Close();
        response.Close();

        return result.ToString();
    }
    catch (Exception ex)
    {
    }
    return null;
}

推薦答案

會(huì)不會(huì)是網(wǎng)絡(luò)代理干擾?嘗試使用以下方法繞過代理:

Could it be a web proxy interfering? Try to get around the proxy by using the following:

reqFTP.Proxy = GlobalProxySelection.GetEmptyWebProxy();

這篇關(guān)于想使用 C# (FtpWebResponse) 從 FTP 讀取文件列表，但它返回 HTML的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
