C#：WebClient - 无法识别西里尔字符

编程问答 2022-05-30

问题描述

尝试解析站点：link

下载内容的代码：

WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.ASCII; // OR UTF8
string reply = client.DownloadString(url);

回复：

<!DOCTYPE HTML>
<html prefix="og: http://ogp.me/ns#">
<head><Meta http-equiv="Content-Type" content="text/html; charset=windows-1251">
    <link rel="icon" type="image/vnd.microsoft.icon" href="https://spravnik.com/favicon.ico"/>
    <link rel="SHORTCUT ICON" href="https://spravnik.com/favicon.ico"/>
    <link href="/src/main.css?v=1.25" rel="stylesheet" type="text/css" />
    <script src="https://cdn.contentsitesrv.com/js/push/subscribe.js?v=1.3.0"></script>
<title>??????????? 12 ??????? ??. - ?????????? ?????????? ??????</title>
<Meta name="keywords" content="?????????? ?????????? ????????????,???? 09 ????????????,?????????? ????? ????????????"/>
<Meta name="description" content="? ??????????? &#9742; ????????? ?? ??????? ????? ??? ???? ???????????? ?? 12 ??????? ??. ????? ???????? ?? ?????? ????????,?????? ???????? ????? ???????? ? ????? ?? ?????? ????????."/>
<Meta property="og:title" content="?????????? ??????????. ??????????? ? ?? ??????...!"/>

所有西里尔字符都转换为“???”或者在����

解决方法

看起来这个站点只是忽略了您的客户端编码并以 1251 编码返回您的数据。我更喜欢使用 RestClient 并检查响应 ContentType。但是，如果您对这个网站有绝对的把握 - 下面的代码可以正常工作。

WebClient client = new WebClient {Encoding = Encoding.UTF8};
byte[] reply = client.DownloadData(url);

Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
Encoding encoding1251 = Encoding.GetEncoding("windows-1251");
var convertedBytes = Encoding.Convert(encoding1251,Encoding.UTF8,reply);

string result = Encoding.UTF8.GetString(convertedBytes);
