问题
I'm using EWS GetItem operation to fetch data from exchange server, but i've got following error
Error 401 fault: SOAP-ENV:Server[no subcode]
"HTTP Error"
Detail: HTTP/1.1 401 Unauthorized
However my login credential are correct, since those are works well with findItem request and response, but when GetItem request goes to server it give above error. My credentials are like:
soap *pSoap = proxy->soap;
proxy->soap_endpoint = "https://outlook.office365.com/ews/exchange.asmx";
pSoap->userid = "abcd@abcd.onmicrosoft.com";
pSoap->passwd = "abcd1234";
And Received log are like
HTTP/1.1 200 OK

What could be possibly wrong here, why one request pass and another fail? any idea? thank you.
回答1:
I got it!!, it's error occurs just because of my second request not able to login on the exchange server. since i've provided my credentials only once, So when findItem Response come, connection with the server is 'closed' and my next subsequent request not able to login. so i've to login once again to the server.
