[英]How to resolve the email address of Exchange Server 2003 using WebDAV code
[英]WebDAV Exchange 2003 failing when specifying a date
我正在使用以下代碼從 Exchange 2003 服務器檢索電子郵件。 周五一切正常,現在失敗了。
通過一些調查,我將其范圍縮小到 targetDate 變量。 似乎日期是在四月,它會失敗並從服務器返回 400。 我已將此行注釋掉並嘗試了 2012-3-29、2012-4-1、2012-4-10(今天)的各種日期,而 4 月的日期似乎失敗了。
某種病態的愚人節玩笑?
代碼本身來源於這篇文章: http://www.codeproject.com/Articles/42458/Using-Exchange-2003-with-Webdav-Send-Retrieve-Atta
public XmlDocument GetMailAll()
{
HttpWebRequest request = default(HttpWebRequest);
HttpWebResponse response = default(HttpWebResponse);
string rootUri = null;
string query = null;
byte[] bytes = null;
Stream requestStream = default(Stream);
Stream responseStream = default(Stream);
XmlDocument xmlDoc = default(XmlDocument);
xmlDoc = new XmlDocument();
try
{
DateTime targetDateTime = DateTime.Today.AddDays(-5);
String targetDate = ""+targetDateTime.Year + "-" + targetDateTime.Month + "-" + targetDateTime.Day;
rootUri = server + "/Exchange/" + alias + "/" + inbox;
query = "<?xml version=\"1.0\"?>"
+ "<D:searchrequest xmlns:D = \"DAV:\" xmlns:m=\"urn:schemas:httpmail:\">"
+ "<D:sql>SELECT \"urn:schemas:httpmail:hasattachment\", \"DAV:displayname\", "
+ "\"urn:schemas:httpmail:from\", \"urn:schemas:httpmail:subject\", "
//+ "\"urn:schemas:httpmail:htmldescription\"," //Return full body (not necessary right now)
+ "\"urn:schemas:httpmail:datereceived\", \"urn:schemas:httpmail:read\" FROM \"" + rootUri
+ "\" WHERE \"DAV:ishidden\" = false "
+ "AND \"DAV:isfolder\" = false "
//+ "AND \"urn:schemas:httpmail:read\" = false"
+ "AND \"urn:schemas:httpmail:datereceived\" >= CAST(\"" + targetDate + "T00:00:000Z\" AS 'dateTime.tz')"
+ "</D:sql></D:searchrequest>";
request = (HttpWebRequest)WebRequest.Create(rootUri);
request.Timeout = 5000;
request.Credentials = new NetworkCredential(alias, password, domain);
request.Method = "SEARCH";
request.ContentType = "text/xml";
request.Headers.Add("Translate", "F");
bytes = System.Text.Encoding.UTF8.GetBytes(query);
request.ContentLength = bytes.Length;
requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
response = (HttpWebResponse)request.GetResponse();
authCookies = new List<Cookie>();
foreach(Cookie cookie in response.Cookies)
{
authCookies.Add(cookie);
}
responseStream = response.GetResponseStream();
xmlDoc.Load(responseStream);
responseStream.Close();
}
catch (WebException ex)
{
if (ex.Response == null)
{
throw new Exception();
}
else if ((ex.Response as HttpWebResponse).StatusCode == HttpStatusCode.Unauthorized)
{
throw new ExchangeCatastrophicException();
}
else
{
throw new ExchangeFailedException();
}
}
catch (Exception ex)
{
throw;
}
return xmlDoc;
}
終於讓它工作了。 要投射的確切目標日期(包括 T00:00:..Z 部分)必須符合http://msdn.microsoft.com/en-us/library/aa123600%28v=exchg.65%29.aspx上的規范
我現在有:
DateTime targetDateTime = DateTime.Today;
string targetDate = targetDateTime.ToString("yyyy-MM-dd");
剪輯
+ "AND \"urn:schemas:httpmail:datereceived\" >= CAST(\"" + targetDate + "T00:00:00Z" + "\" AS 'dateTime.tz')"
請注意,秒部分是兩個零而不是三個。
