⚠️ ATTENTION !

Make sure your authorization service can be accessed normally, otherwise the request may fail
Make sure your relevant request address and URL information are filled in correctly, otherwise the request will not be able to proceed normally
Considering the differences in authorization server requests and return data of different companies, you need to fill in the request template when configuring. The template supports five placeholders: {ClientId}, {ClientSecret}, {Code}, {AccessToken}, {AccessTokenType}. You need to fill in the correct placeholders in the template. Only one level of nesting is supported, not multiple levels of nesting.
The Content-Type of the HTTP request is application/json. When obtaining user information, the HTTP Header will automatically carrythe Authorization: {AccessToken} or Authorization: Bearer {AccessToken} key- value pair.

4. Configuration process description (taking GITHUB as an example)

Authorization Server URL:

that is, the authorization address of the Github authorization server. https://github.com/login/oauth/authorize

if your application needs to bring more parameters, you can configure them here.

Get the Token:

the interface of access_token is obtained by using the code (authorization code) called back by the authorization server.

By configuring the request parameters and returning data, through placeholders (refer to the above 【 placeholder Description ])

descript

Get user information:

you can use the access_token and token_type obtained through the preceding API to obtain user information. After obtaining the user information, it will return the data you configured through {MatchPuDuAccount} placeholder to match the account number field in the Purdue account number.

- Note that currently only the token_type of the bearers is supported. If it is not passed, it will be passed in the header by default. Pass the Authorization value.

descript

After the configuration is completed and saved successfully. A jump address will be generated below.

Shaped: [Purdue Certification Service Address]/v1/jump/【 Client ID ]]

HTTPS://LOGIN-CXG-TEST-INTEMALPUDU.WORK/V1JUMP/LV23LITOU6E04YUBRZVG

jump Address

descript

if you need to jump to a specified address, you can specify the jump by adding the redirect_uri parameter to the jump address (note that this parameter needs to be encoded).

5. Common errors

If an error message appears during use and the prefix of the message is the error code, the possible error causes are as follows:

Error Code	Possible Causes of Errors
3133	the user matching field is filled in. The interface for obtaining user information on your authorization server does not return the modified field or the returned field is null.

3135	error in obtaining your authorization configuration information, please check whether your login-free configuration is correct.
3137	the token url for obtaining your Authorization Service or the url for obtaining user information is incorrect, please check whether your login-free configuration is correct.

3139	an error occurred in calling your url to obtain the token. Please check whether your url is correctly filled in, your url request parameters are correct, and your url request parameter placeholder is used correctly. If your authorization server has mandatory verification of [redirect_uri], please check whether your callback address in your authorization server is correctly filled in
3140	when calling your url to obtain the token, an error occurred when parsing the return parameter. Please check whether the placeholder for your return parameter is correct.
3141	An error occurred in calling your url for obtaining user information. Check whether your url is correctly filled in and whether your url request parameters are correct.
