Question

我正在运行由Exchange2010构建的.NET中具有自动生成的代理类的交换同步应用程序。

现在，我需要设置HttpHeaders：

service.HttpHeaders.Add("X-AnchorMailbox", Mailbox.SMTPAddress);
service.HttpHeaders.Add("X-PreferServerAffinity", "true");

就像这里描述的那样： Maintain affinity in exchange

但是它指的是EWS托管API，我无法在我的ExchangeServiceBindingObject中找到此属性。那么如何在自动生成的代理中设置此标头？

我会尝试使用EWS Managed Api而不是尝试自己动手。如果那不是一个选择，则可以通过覆盖ExchangeServiceBinding上生成的GetWebRequest方法来添加httpheaders，以使其到达标题，如下所示：

public class ExchangeServiceBindingWithHeaders : EwsProxy.ExchangeServiceBinding
{
    private NameValueCollection _customHeaders = new NameValueCollection();

    public void AddHeaders(string key, string value)
    {
        _customHeaders.Add(key, value);
    }

    protected override WebRequest GetWebRequest(Uri uri)
    {
        HttpWebRequest req = (HttpWebRequest)base.GetWebRequest(uri);
        req.Headers.Add(_customHeaders);

        return req;
    }
}

然后，您可以调用新的派生类以添加自定义标头：

ExchangeServiceBindingWithHeaders service = new ExchangeServiceBindingWithHeaders();
service.RequestServerVersionValue = new RequestServerVersion();
service.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2010;
service.Credentials = new NetworkCredential("<username>", "<password>", "<domain>");
service.Url = @"https://<FQDN>/EWS/Exchange.asmx";

service.AddHeaders("X-AnchorMailbox", "some@emailaddress.com");
service.AddHeaders("X-PreferServerAffinity", "true");

在ews自动生成的代理中设置HttpHeader
