Question

我遇到了一个问题，并认为我可能会遗漏一些RestSharp。我正在授权并回复一个cookie就好了......见下文。但是当我打电话来获取数据时，它会返回未经授权的数据。它在Postman中运行得很好，但在下面的代码中没有。我正在使用控制台应用程序，我试图通过AddHeader，AddCookie发送cookie，并作为参数。 responseLogin确实包含正确的cookie。任何帮助都会很棒。

    Dim clientLogin = New RestClient("http://[URI to Authorize]............")
    Dim requestLogin = New RestRequest(Method.POST)

    requestLogin.AddParameter("application/x-www-form-urlencoded", "[Username and password here.....]", ParameterType.RequestBody)
    Dim responseLogin As IRestResponse = clientLogin.Execute(requestLogin)




    Dim client = New RestClient("http://[URI to get data]............")
    Dim request = New RestRequest(Method.GET)

    request.AddHeader("Cookie", responseLogin.Cookies(0).Value.ToString)
    request.AddHeader("Accept", "application/json")

    Dim response As IRestResponse = client.Execute(request)

Cookie标头需要包含cookie的名称和值，例如

Dim authCookie = responseLogin.Cookies(0) ' Probably should find by name
request.AddHeader("Cookie", String.Format("{0}={1}", authCookie.Name, authCookie.Value))

然而，the documentation（我从未亲自使用过RestSharp）说RestSharp自动支持cookie，所以如果你重用RestClient实例并设置CookieContainer你就不应该'我需要做任何事情来手动处理cookie（除非你想要，在某些情况下可能更好）。

Dim client = New RestClient(New Uri("[Base URI...]"))
client.CookieContainer = New System.Net.CookieContainer()

Dim requestLogin = New RestRequest("[login page path]", Method.POST)
requestLogin.AddParameter("application/x-www-form-urlencoded", "[Username and password here.....]", ParameterType.RequestBody)
Dim responseLogin As IRestResponse = client.Execute(requestLogin)

Dim request = New RestRequest("[data api path", Method.GET)
request.AddHeader("Accept", "application/json")
Dim response As IRestResponse = client.Execute(request)

您可能只是重复使用不同RestClient个实例的Cookie容器，而不是重用client。

我在 RestClient .NET 框架 4.5.2 版本上遇到了同样的问题。事实证明，您必须实现 IAuthenticator 接口。

 public class MyAuth : IAuthenticator
{
    readonly string _password;
    readonly string _passwordKey;
    readonly string _username;
    readonly string _usernameKey;

    public MyAuth(string usernameKey, string username, string passwordKey, string password)
    {
        _usernameKey = usernameKey;
        _username = username;
        _passwordKey = passwordKey;
        _password = password;
    }

    public void Authenticate(IRestClient client, IRestRequest request)
        => request
            .AddCookie(_usernameKey, _username)
            .AddCookie(_passwordKey, _password);
            //.AddParameter(_usernameKey, _username)
            //.AddParameter(_passwordKey, _password);
            
}

我做到了，我的要求奏效了。
