使用 WebClient 下载 JSON 会导致奇怪的类似 unicode 的字符？
Downloading JSON with WebClient results in weird unicode-like characters?
问：
因此，我可以在浏览器中发出请求，https://search.snapchat.com/lookupStory?id=itsmaxwyatt
它会给我一个 JSON，但是如果我通过 Web 客户端执行此操作，它似乎会给我一个非常混淆的字符串？我可以提供所有内容，但现在被截断了：
x ƽ o Cjnjivenko _ ˗ 89： / [ / h #l ٗC U. gH ， qOv _ _ σҭ
所以，这里是 Csharp 代码：
using var webClient = new WebClient();
webClient.Headers.Add ("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:89.0) Gecko/20100101 Firefox/89.0");
webClient.Headers.Add("Host", "search.snapchat.com");
webClient.DownloadString("https://search.snapchat.com/lookupStory?id=itsmaxwyatt")
我也尝试过在没有任何标头的 http rest 客户端中，它仍然返回 JSON。
尝试编码：
using var webClient = new WebClient();
webClient.Headers[HttpRequestHeader.AcceptEncoding] = "gzip";
webClient.Encoding = Encoding.UTF8;
webClient.Headers.Add ("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:89.0) Gecko/20100101 Firefox/89.0");
webClient.Headers.Add("Host", "search.snapchat.com");
Console.WriteLine(Encoding.UTF8.GetString(webClient.DownloadData("https://search.snapchat.com/lookupStory?id=itsmaxwyatt")));

根据@Progman评论，您需要执行以下操作：
// You can define other methods, fields, classes and namespaces here
class MyWebClient : WebClient
{
protected override WebRequest GetWebRequest(Uri address)
{
HttpWebRequest request = base.GetWebRequest(address) as HttpWebRequest;
request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;
return request;
}
}
void Main()
{
using var webClient = new MyWebClient();
webClient.Headers.Add("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:89.0) Gecko/20100101 Firefox/89.0");
webClient.Headers.Add("Host", "search.snapchat.com");
var str = webClient.DownloadString("https://search.snapchat.com/lookupStory?id=itsmaxwyatt");
Debug.WriteLine(str);
}
