Scan Code

scanCode

TIP

The API usage is as follows: wx.scanCode(Object object)
This API is supported by mini programs, but not by mini games.

• Functional description: Call up the client code scanning interface to scan

• Parameters and descriptions: Object object。

  Properties	Type	Legal values	Default value	Required	Description
  onlyFromCamera	boolean	-	false	No	Whether the code can only be scanned from the camera, and pictures cannot be selected from the album
  scanType	Array.<string>	1. barCode：One-dimensional code 2. qrCode：Two-dimensional code 3. datamatrix：Data Matrix code 4.pdf417：PDF417 barcode	['barCode', 'qrCode']	No	Scanning type
  success	Function	-	-	No	Callback function for successful interface call
  fail	Function	-	-	No	Callback function for failed interface call
  complete	Function	-	-	No	Callback function for interface call completion (executed regardless of success or failure)

• object.success callback function parameters: Object object。

  Properties	Type	Legal values	Description
  result	string	-	Content of the scanned code
  scanType	string	1.QR_CODE：Two-dimensional code 2. AZTEC：One-dimensional code 3. CODABAR：One-dimensional code 4.CODE_39：One-dimensional code 5. CODE_93：One-dimensional code 6. CODE_128：One-dimensional code 7. DATA_MATRIX：Two-dimensional code 8.EAN_8：One-dimensional code 9.EAN_13：One-dimensional code 10. ITF：One-dimensional code 11. datamatrix：One-dimensional code 12.PDF_417：Two-dimensional code 13. RSS_14：One-dimensional code 14. RSS_EXPANDED：One-dimensional code 15. UPC_A：One-dimensional code 16.UPC_E：One-dimensional code 17. UPC_EAN_EXTENSION：One-dimensional code 18. WX_CODE：Two-dimensional code 19.CODE_25：One-dimensional code	Type of the scanned code
  charSet	string	-	Character set of the scanned code
  path	string	-	When the scanned code is the current mini program QR code, this field will be returned, and the content is the path carried by the QR code
  rawData	string	-	Original data, base64 encoding

• Sample code:

// Allow scanning from both the camera and album
wx.scanCode({
  success(res) {
    console.log(res);
  },
});

// Allow scanning from the camera only
wx.scanCode({
  onlyFromCamera: true,
  success(res) {
    console.log(res);
  },
});
