Some use of SMS interface for China Telecom Sky-wing open platform

Description of the section that gets the access token:

Development of sky-Wing SMS Interface Document link: http://open.189.cn/index.php?m=content&c=index&a=lists&catid=62

Actually getting tokens is very simple, which is to assemble the interface address and the required parameters according to the instructions of the SMS interface, then send a POST request and then be able to get to the returned JSON-formatted string.

Based on the SMS interface just above, we choose the simplest way to get tokens, that is, " application two " in the document.

Application two: Under the standard client credentials authorization mode (CC licensing mode) of OAuth 2.0, the application can invoke the interface by its own application ID and application key. Direct access to an at access token without user authorization (User-independent access token, referred to as Uiat).

Unlike a normal at token, the Uiat token can only be used to invoke an open API interface that does not require user authorization, such as a music list, while a normal at token can be used to invoke an open API interface that requires user authorization and to invoke an open interface that does not require user authorization. Uiat tokens are used in collaborative applications where user logons are not required, although their use is relatively limited in scope than ordinary at tokens, but the data form is basically consistent.

, the code executes the result:
