CK1 OpenApi Documentation

Authorization

Your app cannot access users' data through openapi without authenticating itself first. Ck1 uses the OAuth 2.0 specification to identify which apps are allowed access to resources.

The AccessToken is the app's password that it uses to access users' data.

This guide will walk you through the authentication process.

1. Asking for Permission

   The first step is to get permission from the user. Please direct the user to this URL:

   Get  https://openapi.chukou1.cn:82/oauth2/authorization?client_id={client_id}&response_type={response_type}&scope={scope}&redirect_uri={redirect_uri}

   Name	Description	Example
   client_id	Your app's client ID	M2Q3YTM4MTctMDM0Mi00NGUzLTk4OTctYjA5ZTViMjlkOTBi
   response_type	Should be 'code' or 'token'. Use 'code' for this guide.	code
   scope	Scope of authority, use ',' for many scopes. Use 'OpenApi' for this guide.	OpenApi
   redirect_uri	Your app's redirect uri that you specified when you created the app.	http://www.example.com/api/gettoken

2. Receiving the Authorization Code

   After the user grants permission to your app, Ck1 will redirect the user to the redirect URI specified when the app was created. One of the parameters of this request is the Authorization Code.

   http://www.example.com/api/gettoken?code={code}

3. Obtaining the Access Token

   Post  https://openapi.chukou1.cn:82/oauth2/token?client_id={client_id}&client_secret={client_secret}&redirect_uri={redirect_uri}&grant_type={grant_type}&code={code}

   Name	Description	Example
   client_id	Your app's client ID	M2Q3YTM4MTctMDM0Mi00NGUzLTk4OTctYjA5ZTViMjlkOTBi
   client_secret	Your app's client secret	abbcb34d-c4a6-47b5-bf60-26994d7eb36d
   redirect_uri	Your app's redirect uri that you specified when you created the app	http://www.example.com/api/gettoken
   grant_type	The string 'authorization_code'	authorization_code
   code	The authorization code you received	NGZhNWNjYzgtY2Y3Ni00M2I1LTljOTItOTQyZGEzN2VkOTBi

       Remarks：AccessToken expires time is one month. You can obtain a new AccessToken through the RefreshToken after a certain period of time.
   After you obtain a new AccessToken, the old AccessToken is Invalid

4. Making Authorized Requests

   To make an authorized request, add the following to the request header:

   Authorization: Bearer {AccessToken}
   Content-Type: application/json; charset=utf-8

5. Obtaining New Access Tokens

       Access tokens expire after a certain period of time. In order to obtain a new access token without going through the full oAuth process again, your app can make the following request:

   Post  https://openapi.chukou1.cn:82/oauth2/token?client_id={client_id}&client_secret={client_secret}&redirect_uri={redirect_uri}&grant_type={grant_type}&refresh_token={refresh_token}
