我刚开始使用 awesomium。我想了解如何更改用户代理和推荐人。例如，我需要初始化 5 istance o awesomium webcontrol，对于它们中的每一个，我需要不同的用户代理和不同的推荐人。这是我的简单代码

        private void newbrowser()
    {
            browser = new Awesomium.Windows.Forms.WebControl();
            browser.Paint += browser_Paint;
            browser.Location = new System.Drawing.Point(1, 1);
            browser.Name = "webControl";
            browser.Size = new System.Drawing.Size(1024, 768);
            browser.Source = new System.Uri("https://www.google.com/", System.UriKind.Absolute);
            browser.TabIndex = 0;

    }

    void browser_Paint(object sender, PaintEventArgs e)
    {
        browser.Paint -= browser_Paint;

        System.Collections.Specialized.NameValueCollection myCol =
            new System.Collections.Specialized.NameValueCollection();
        myCol.Add("Referer", "http://www.yahoo.com");

        browser.SetHeaderDefinition("MyHeader", myCol);
        browser.AddHeaderRewriteRule("http://*", "MyHeader");
    }
    private void button1_Click(object sender, EventArgs e)
    {
        newbrowser();
    }

这 2 行给出了一个错误

        browser.SetHeaderDefinition("MyHeader", myCol);
        browser.AddHeaderRewriteRule("http://*", "MyHeader");

错误 1“Awesomium.Windows.Forms.WebControl”不包含“SetHeaderDefinition”的定义错误1“Awesomium.Windows.Forms.WebControl”不包含“AddHeaderRewriteRule”的定义

谢谢您的帮助

您需要设置管理 WebControl 的 WebCore 的用户代理。这必须在您创建 WebControl 之前完成。

public WebForm()
{
    if ( !WebCore.IsRunning )
        WebCore.Initialize( new WebConfig() { UserAgent = "YourUserAgent" } );

    InitializeComponent();
}

我的解决方案 - 是 WebBrowser 的包装器，它实现了 IResourceInterceptor 并且可以使用任何其他标题进行导航：

public class class BrowserWrapper : IResourceInterceptor
{
    public BrowserWrapper()
    {
        WebCore.ResourceInterceptor = this;
        //BrowserWrapper can contains WebBrowser or knows how to delegate him Naviagtion (Source property)
    }

    private readonly ConcurrentDictionary<Uri, string> headers = new ConcurrentDictionary<Uri, string>();

    public void Navigate(Uri uri, string additionalHeaders = null)
    {
        if (additionalHeaders != null) headers.AddOrUpdate(uri, additionalHeaders, (url, h) => h);
        //Navigation to browser (WebControl.Source = uri...)
    }

    ResourceResponse IResourceInterceptor.OnRequest(ResourceRequest request)
    {
        string h;
        if (headers.TryRemove(request.Url, out h))
        {
            var hs = h.Split(':');
            request.AppendExtraHeader(hs[0], hs[1]);
        }
        return null;
    }

    bool IResourceInterceptor.OnFilterNavigation(NavigationRequest request)
    {
        return false;
    }
}
