CodeIdentificationService#identifyCode

When the MPP cannot recognize the code value, use this API to check whether the code can be processed by Alipay+.

Request parameters

Parameters

Item	Type	Length	Description	Required
request	CodeIdentificationRequest	/	Code identification request	M

CodeIdentificationRequest

Item	Type	Length	Description	Required
codeValue	String	8192	The code value that cannot be recognized by the MPP	M

Response parameters

CodeIdentificationResult

Item	Type	Length	Description	Required
isSupported	boolean	/	The parameter indicates whether the code can be processed by Alipay+.	M
postCodeMatchActionType	String	/	The further action that needs to be taken if the code can be processed by Alipay+. Valid values are: `DECODE`: indicates that the code is an order code and the MPP needs to send a request to Alipay+ to decode the code value. `OPEN_URL`: indicates that the code is an entry code and the MPP needs to redirect the user to place an order. Note: Returned by Alipay+ if the value of the isSupported parameter is `true`.	O
codeValue	String	/	The code value that is to be decoded. Note: Returned by Alipay+ if the value of the postCodeMatchActionType parameter is `DECODE`.	O
redirectUrl	String	/	The URL to which the user needs to be redirected to place an order. Note: Returned by Alipay+ if the value of the postCodeMatchActionType parameter is `OPEN_URL`.	O
userAgent	String	/	The additional user-agent information that needs to be added. The default value of this parameter is `-`. Note: Returned by Alipay+ if the value of the postCodeMatchActionType parameter is `OPEN_URL`. The additional user-agent string is in the format of `-/[String_Value]`.	O
acDecodeConfig	String	/	Extended information for Alipay+ Client SDK to use. Note: Returned by Alipay+ if the value of the isSupported parameter is `true`.	O

Result code

resultCode	resultStatus	resultMessage
SUCCESS	S	Success
PARAM_ILLEGAL	F	Illegal parameters exist. For example, a non-numeric input, or an invalid date.
UNKNOWN_EXCEPTION	U	The API calling failed because of unknown reasons.

Result processing logic

If result.resultStatus is S, the code identification is successful. See the following list for details:

If isSupported is true, the code can be processed by Alipay+.

If postCodeMatchActionType is DECODE, the code is an order code and the MPP needs to send a request to Alipay+ to decode the code value.
If postCodeMatchActionType is OPEN_URL, the code is an entry code and the MPP needs to redirect the user to place an order based on the redirectUrl and userAgent parameters.

If isSupported is false, the code cannot be processed by Alipay+.

If result.resultStatus is F, code identification failed. The MPP can handle the result based on result codes.
If result.resultStatus is U, unknown exceptions occur during the code identification and the MPP can check logs to view details. The MPP also might retry.

Sample

copy
CodeIdentificationRequest request = new CodeIdentificationRequest();
request.setCodeValue("28100104df2342342****");
CodeIdentificationResult result = codeIdentificationService.identifyCode(request);
if (result.getResult().getResultStatus().equals("S") && result.isSupported()){
    // the code should be processed by Alipay+
}
if (result.getResult().getResultStatus().equals("F"){
    // Please pay attention to resultCode
}
