我正在测试Microsoft Exchange Web服务Java API(版本1.2)以从服务器读取邮件.这是我的代码:
String url = "https://my-server/EWS/exchange.asmx"; ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); service.setTraceEnabled(true); service.setCredentials(new WebCredentials("user","password")); service.setUrl(url.toURI()); MailBox mailBox = new MailBox("foo@bar.com"); FolderId folder = new FolderId(WellKNownFolderName.InBox,mailBox); ItemView view = new ItemView(10); view.getorderBy().add(ItemSchema.DateTimeReceived,SortDirection.Descending); FindItemsResults<Item> items = service.findItems(folder,view);
Exception in thread "main" microsoft.exchange.webservices.data.EWSHttpException: Connection not established at microsoft.exchange.webservices.data.HttpClientWebRequest.throwIfConnIsNull(UnkNown Source) at microsoft.exchange.webservices.data.HttpClientWebRequest.getResponseCode(UnkNown Source) at microsoft.exchange.webservices.data.EwsUtilities.formatHttpResponseHeaders(UnkNown Source) at microsoft.exchange.webservices.data.ExchangeServiceBase.traceHttpResponseHeaders(UnkNown Source) at microsoft.exchange.webservices.data.ExchangeServiceBase.processHttpResponseHeaders(UnkNown Source) at microsoft.exchange.webservices.data.SimpleServiceRequestBase.internalExecute(UnkNown Source) at microsoft.exchange.webservices.data.MultiResponseServiceRequest.execute(UnkNown Source) at microsoft.exchange.webservices.data.ExchangeService.findItems(UnkNown Source) at microsoft.exchange.webservices.data.ExchangeService.findItems(UnkNown Source) at foo.bar.TestMail.main(TestMail.java:52)
我无法理解当前代码的错误.你有任何线索,或至少一些测试尝试?
请注意,我的Java代码可以访问Web服务(https // my-server / exchange.asmx).
不确定它是否可以提供帮助,但我发现在日志显示的跟踪中:
<Trace Tag="EwsResponse" Tid="1" Time="2013-01-28 10:47:03Z"> <html><head><title>Error</title></head><body>The function requested is not supported </body></html> </Trace>
编辑
我做了另一个测试.这一次,我使用默认凭据 – 所以我自己的电子邮件帐户 – 使用service.setUseDefaultCredentials(true);而不是设置WebCredentials对象.连接仍然没有建立,但我得到另一个错误(我只采取了跟踪日志的有趣部分):
<h1>You are not authorized to view this page</h1> You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept. (...) <h2>HTTP Error 401.2 - Unauthorized: Access is denied due to server configuration.<br>Internet information Services (IIS)</h2>
当然,我无法在Exchange服务器端访问或更改任何内容.有没有办法使身份验证成功?
解决方法
问题是由于使用的身份验证方案.默认情况下,EWS使用NTLM,但我的Exchange服务器未配置为接受此类身份验证.我必须使用LDAP身份验证.
