【问题描述】：

尝试从网站收集信息时：

DefaultHttpRequester req = new DefaultHttpRequester();

req.Headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0";
 
IConfiguration config = Configuration.Default.With(req).WithDefaultLoader().WithDefaultCookies();

var afdas = BrowsingContext.New(config).OpenAsync("https://www.wg-gesucht.de/api/profiles/contact-data/5520144?asset_type=0&asset_id=6839242").Result;

我收到一条错误消息：

<html>
   <head></head>
   <body>{"type":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html","title":"Not Acceptable","status":406,"detail":"Cannot honor Accept type specified"}</body>
</html>

基于错误消息：

https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

406 不可接受

请求标识的资源只能生成具有不可接受的内容特征的响应实体根据请求中发送的接受标头。

除非它是一个 HEAD 请求，否则响应应该包含一个实体包含可用实体特征和位置的列表用户或用户代理可以从中选择最合适的一个。实体格式由给出的媒体类型指定内容类型标头字段。取决于格式和用户代理的能力，选择最合适的选择可以自动执行。然而，这个规范没有为这种自动选择定义任何标准。
  Note: HTTP/1.1 servers are allowed to return responses which are
  not acceptable according to the accept headers sent in the
  request. In some cases, this may even be preferable to sending a
  406 response. User agents are encouraged to inspect the headers of
  an incoming response to determine if it is acceptable.
如果响应可能不可接受，用户代理应该暂时停止接收更多数据并询问用户以进一步决定行动。

我已经添加了所有可以在 Firefox 中看到的标题：

DefaultHttpRequester req = new DefaultHttpRequester();

req.Headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0";
req.Headers["Accept"] = "*/*"; // https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept
req.Headers["Accept-Encoding"] = "gzip, deflate, br";
req.Headers["Accept-Language"] = "de,en-US;q=0.7,en;q=0.3";
req.Headers["Connection"] = "keep-alive";
req.Headers["Sec-Fetch-Dest"] = "document";
req.Headers["Sec-Fetch-Mode"] = "navigate";
req.Headers["Sec-Fetch-Site"] = "cross-site";
req.Headers["Upgrade-Insecure-Requests"] = "1";
 
IConfiguration config = Configuration.Default.With(req).WithDefaultLoader().WithDefaultCookies();

var afdas = BrowsingContext.New(config).OpenAsync("https://www.wg-gesucht.de/api/profiles/contact-data/5520144?asset_type=0&asset_id=6839242").Result;

但我仍然遇到同样的错误，那我做错了什么？

【问题讨论】：

代码中似乎存在错误。您可以尝试使用正确的配置吗？例如DefaultHttpRequester req = new DefaultHttpRequester(); req.Headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0"; IConfiguration Config = Configuration.Default.With(req).WithDefaultLoader().WithDefaultCookies(); var afdas = BrowsingContext.New(Config).OpenAsync("https://www.wg-gesucht.de/api/profiles/contact-data/5520144?asset_type=0&asset_id=6839242").Result;

【解决方案1】：

这对我有用

DefaultHttpRequester req = new DefaultHttpRequester();

            req.Headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0";

            IConfiguration Config = Configuration.Default.With(req).WithDefaultLoader().WithDefaultCookies();

            var afdas = BrowsingContext.New(Config).OpenAsync("https://www.wg-gesucht.de/api/profiles/contact-data/5520144?asset_type=0&asset_id=6839242").Result;

我还是得到了 ("{"type":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html","title":" Not Acceptable","status":406,"detail":"Cannot Honor Accept type specified"}") ... 回复应该是like this，你确定你收到回复了吗？
