我的Xamarin项目中有以下计划:
现有API(非公开)提供System.Net.CookieCollection。
如何使用带有这些Cookie的POST请求来实现我的想法?这是我的基础:
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class WebPage : ContentPage
{
public WebPage(string url, CookieCollection cookies)
{
InitializeComponent();
BindingContext = new MainPageViewModel();
MyWebView.Source = "https://" + url;
}
}

您必须在Android和iOS上为WebView
创建自定义渲染器。这样,您就可以将Cookie注入Android WebView
和iOS UIWebView
。如果您不熟悉它们,请从这里开始:Introduction to Custom Renderers
如果您熟悉呈现器的工作方式,请在Xamarin论坛上Christine Blanda关注此帖:Setting Cookies in a WebView
我也会在此处发布代码,以确保在原始帖子发布时保留该代码。
Android OnElementChanged
var cookieManager = CookieManager.Instance;
cookieManager.SetAcceptCookie(true);
cookieManager.RemoveAllCookie();
var cookies = UserInfo.CookieContainer.GetCookies(new System.Uri(AppInfo.URL_BASE));
for (var i = 0; i < cookies.Count; i++)
{
string cookieValue = cookies[i].Value;
string cookieDomain = cookies[i].Domain;
string cookieName = cookies[i].Name;
cookieManager.SetCookie(cookieDomain, cookieName + "=" + cookieValue);
}
iOS OnElementChanged
// Set cookies here
var cookieUrl = new Uri(AppInfo.URL_BASE);
var cookieJar = NSHttpCookieStorage.SharedStorage;
cookieJar.AcceptPolicy = NSHttpCookieAcceptPolicy.Always;
foreach (var aCookie in cookieJar.Cookies)
{
cookieJar.DeleteCookie(aCookie);
}
var jCookies = UserInfo.CookieContainer.GetCookies(cookieUrl);
IList<NSHttpCookie> eCookies =
(from object jCookie in jCookies
where jCookie != null
select (Cookie) jCookie
into netCookie select new NSHttpCookie(netCookie)).ToList();
cookieJar.SetCookies(eCookies.ToArray(), cookieUrl, cookieUrl);
