Webclient UploadValues encoding

本文关键字：encoding UploadValues Webclient | 更新日期: 2023-09-27 18:18:44

我在URL中制作POST并获得响应作为这样的字符串:

var responseBytes = client.UploadValues("www.example.com", requestData.Body);
var html = Encoding.UTF8.GetString(responseBytes, 0, responseBytes.Length);
html = HttpUtility.HtmlDecode(html);

我创建了一个子WebClient来接受cookie，所以我创建了这个类:

 public class CookieWebClient : WebClient
{
    public CookieContainer CookieContainer { get; }
    public CookieWebClient()
    {
        CookieContainer = new CookieContainer();
        Encoding = Encoding.UTF8;
    }
    public CookieWebClient(CookieContainer cookieContainer)
    {
        CookieContainer = cookieContainer;
    }
    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address) as HttpWebRequest;
        if (request == null) return base.GetWebRequest(address);
        request.CookieContainer = CookieContainer;
        return request;
    }
}
如您所见，我在构造函数中设置了编码。但是当我得到html属性时，一些字符出现了:� necess�rio，它应该是É necessário。

你知道怎么回事吗?

您正在使用"Latin 1"字符(也许是葡萄牙语?)，所以您应该使用:

var html = Encoding.GetEncoding("ISO-8859-1")
                   .GetString  (responseBytes, 0, responseBytes.Length);
