[英]How to authenticate permanently using Restsharp
I am developing an application that pulls data from web and parses it using HtmlAgilityPack. 我正在开发一个从Web提取数据并使用HtmlAgilityPack对其进行解析的应用程序。 However, its not that straight-forward, login is required to access the data. 但是,访问数据并非必须如此简单。
I am using Restsharp to authenticate like this: 我正在使用Restsharp进行这样的身份验证:
//class definitions
request = new RestRequest("http://allpoetry.com/login", Method.POST);
request.AddParameter("utf8", "%E2%9C%93");
request.AddParameter("authenticity_token", "Lr+JtLv7TkZrS73u5scRPbWhuUYDaVF7vd6lkKFF3FKYqNKHircT9v5WCT9EkneTJRsKXaA6nf6fiWopDB0INw==");
request.AddParameter("referer", url); // url to the page I want to go
request.AddParameter("user[name]", "username");
request.AddParameter("user[password]", "password");
request.AddParameter("commit", "Log in");
request.AddHeader("content-type", "application/x-www-form-urlencoded");
response = client.Execute(request);
This works perfectly but the problem is that I can't Login permanently, i can't make another request using this instance of RestRequest class, it gives the error that I am not logged in. I have found a work-around but it doesn't work with some pages, basically I put the url
into the referer
field but I have to make request every time I navigate to another page and this is inconvenient. 这可以正常工作,但问题是我无法永久登录,我无法使用RestRequest类的该实例发出另一个请求,它给出了我未登录的错误。我找到了一种解决方法,但它没有某些页面无法使用,基本上我将url
放入了referer
字段,但是每次我导航到另一个页面时都必须发出请求,这很不方便。
How do I login permanently, so I can make new request from the same instance? 如何永久登录,以便可以从同一实例发出新请求?
Thank you! 谢谢!
After some research, I found that the answer is cookies. 经过研究,我发现答案是饼干。 Each time a request is made, the response has cookies. 每次发出请求时,响应中都有cookie。 I used the cookies like this. 我用这样的饼干。
After response = client.Execute(request)
I added this: 在response = client.Execute(request)
我添加了以下内容:
request.Resource = url;
request.Method = Method.GET;
foreach (var cookie in response.Cookies)
{
request.AddCookie(cookie.Name , cookie.Value); //this adds every cookie in the previous response.
}
response = client.Execute(request);
//use the response as required
This doesn't create a new instance but uses the same request
to make further requests and I am logged in through it all. 这不会创建新实例,但会使用相同的request
进行其他请求,因此我已全部登录。
Thank you everyone for your help! 谢谢你们每一个人的帮助!
