发送 GetItem 请求时出现 HTTP 401 未经授权的错误答案

【问题标题】：HTTP 401 Unauthorized error in sending GetItem Request发送 GetItem 请求时出现 HTTP 401 未经授权的错误
【发布时间】：2015-12-21 04:38:46
【问题描述】：

我正在使用 EWS GetItem 操作从 Exchange 服务器获取数据，但出现以下错误

Error 401 fault: SOAP-ENV:Server[no subcode] "HTTP Error" Detail: HTTP/1.1 401 Unauthorized

但是我的登录凭据是正确的，因为这些凭据与 findItem 请求和响应配合得很好，但是当 GetItem 请求发送到服务器时，它会出现上述错误。我的凭据如下：

soap *pSoap = proxy->soap;
proxy->soap_endpoint = "https://outlook.office365.com/ews/exchange.asmx";
pSoap->userid = "abcd@abcd.onmicrosoft.com";
pSoap->passwd = "abcd1234";

和收到的日志是一样的

这里可能有什么问题，为什么一个请求通过而另一个失败？任何想法？谢谢。

【解决方案1】：

我明白了！！，只是因为我的第二个请求无法登录交换服务器而发生错误。因为我只提供了一次凭据，所以当 findItem 响应到来时，与服务器的连接被“关闭”，我的下一个后续请求无法登录。所以我必须再次登录到服务器。
