问题描述

我正在使用EWS API连接Exchange服务器.建立了连接，但是我没有收到任何回复.

Am using EWS API to connect Exchange server. The connection was established, but I didn’t receive any response.

正在获取异常从服务接收到的响应不包含有效的XML."

Am getting exception "The response received from the service didn't contain valid XML."

内部异常是此XML文档中禁止使用DTD".

The inner Exception was "DTD is prohibited in this XML document."

我没有得到什么是DTD?

I didn’t get what is DTD?

推荐答案

直到(经过多次尝试和错误之后)我才遇到您的问题:

I was getting your problem until (after MUCH trial and error):

1. 将TraceEnabled设置为true，这会将来回消息转储到控制台.

1. set TraceEnabled to true, this will dump the back and forth messages to console.

我使用了URL https://yourexchangeserver/EWS/Exchange.asmx
例如我的工作使用的是亚太地区的BPOS，因此: https://red003.mail .apac.microsoftonline.com/EWS/Exchange.asmx

I used the URL https://yourexchangeserver/EWS/Exchange.asmx
e.g. my work uses BPOS, in asia pacific region, so : https://red003.mail.apac.microsoftonline.com/EWS/Exchange.asmx

请求特定的服务版本，例如ExchangeService服务=新的ExchangeService(ExchangeVersion.Exchange2007_SP1)

Request a specific service version e.g. ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1)

第1步使我摆脱了第一个问题-它提供了Outlook Web Access html页面.
步骤2让我看到它当时正在请求2010_Sp1，但不支持该版本.
步骤3使"Hello world"可以正常工作/发送.

Step 1 got me past your first problem - it was giving the Outlook Web Access html page.
Step 2 let me see that it was then requesting 2010_Sp1, but that version wasn't supported.
Step 3 got "Hello world" working/sending.

如果要使用该服务器，请注意，除2007 SP1之外，我无法采用其他任何版本，因此该URL没有自动发现.

Another note if you use that server, I couldn't get it to take any version except 2007 SP1, and thus, no AutoDiscovery of the URL.

public static string sendMail_BPOS_EWS()
        {
              try
            {
                ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
                service.UseDefaultCredentials = false;
                service.Credentials = new WebCredentials("[e-mail]", "password");

                service.Url = new Uri("https://red003.mail.apac.microsoftonline.com/EWS/Exchange.asmx");
                Console.WriteLine(service.Url);

                service.TraceEnabled = true;

                EmailMessage mail = new EmailMessage(service);
                mail.From = new EmailAddress("[e-mail]");
                mail.ToRecipients.Add("[e-mail]");
                mail.Subject = "Email Subject";
                mail.Body = "Email Body";

                mail.Send();
                return "sent";
            }
            catch (Exception ex)
            {
                return ex.ToString();
            }
        }
