C++ CkHttp AbortCheck Callback

Chilkat classes that involve network communications can use callbacks. This blog post describes the CkHttp AbortCheck callback. An application can request periodic AbortCheck callbacks according to the HeartbeatMs property setting. (If HeartbeatMs = 0, then no AbortCheck callbacks will occur.) For example:

AWS Reference Documentation — Sample Requests and Responses are Important

The AWS Reference Documentation is not consistent.  In some cases, the documentation provides a sample request and sample response.  The samples are extremely helpful, and make it easy to implement the call in any programming language.  With Chilkat, you can usually generate sample code by pasting the sample request, and the body of the sample response into Chilkat’s online tool […]

More Microsoft Graph Misc Notes

Relaying more shared information: “I also wanted to notify you that the “profile” can also be extracted without the use of Graph API (User.Read): https://learn.microsoft.com/en-us/azure/active-directory/develop/id-tokens id_token contains that information and is given along with the access_token but it has to be decoded from a JWT (https://en.wikipedia.org/wiki/JSON_Web_Token) openid, profile, email and offline_access are like some kind of “universal” scopes which can be […]

Microsoft Graph, Outlook, OAuth2, Resources, Audiences…

Is Smartcard Vendor’s low-level lib (dll or so) Required?

Question:  My question is regarding the SharedLib when initializing pkcs11 module.

Answer:  This is a good question.  On a non-Windows system, Chilkat would need to communicate with the […]

Microsoft Azure OAuth2 Redirect URI Notes

Here are some notes regarding OAuth2 Redirect URI’s for Microsoft Azure AD apps. See https://learn.microsoft.com/en-us/azure/active-directory/develop/reply-url A few important points: You can add http://127.0.0.1, and it is preferred over http://localhost because of misconfigured firewalls or hosts file etc.   127.0.0.1 is the loopback address and localhost is just translated into 127.0.0.1. The only pitfall is that you have to add it as […]
