In Yii 2, when processing a RESTful API request, the new response format is supported: text/html, and only the HTML format is supported

1. Open the URL in the browser: http://api.channel-pub-api.localhost/qq/v1/OA uth2/authorize?group_id=015ce30b116ce86058fa6ab4fea4ac63 , which responds to the XML format, because RESTful APIs support both JSON and XML formats. But HTML format is not supported. as shown in Figure 1

Figure 1

2. Open in postman, the value of accept is: application/json; version=0.0, respond to json format, as shown in Figure 2

Figure 2

{
"name": "unprocessable entity",
"message": "Data validation failed: the callback link redirected after the third-party service platform is authorized cannot be empty",
"code": 40004,
"status": 422,
"type": "yii\web\\unprocessableEntityHttpException"
}

3. Now it is necessary to add support for the HTML format, and only support the HTML format, because it is a page, not an interface, and finally jump to the corresponding callback link page, edit \qq\rests\oauth2\authorizeaction.php, set the format attribute, the format attribute specifies the style of the data in data format
