Manage and Optimize a Barcode Recognition Without Cloud Storage

Introduction

Aspose.BarCode for Cloud provided the simplest API which lets you recognize a barcode from file on the server with parameters in the request body. This API can be used with any language: .NET, Java, PHP, Ruby, Rails, Python, jQuery and many more.

API Information

API	Type	Description	Resource Link
/barcode/recognize	POST	Recognize barcode from an url or from request body. Request body can contain raw data bytes of the image or encoded with base64	PostBarcodeRecognizeFromUrlOrContent

cURL Example

Request


// First get Access Token
// Get Client Secret and Client Id from https://dashboard.aspose.cloud/

curl -v "https://api.aspose.cloud/connect/token" -X POST -d 'grant_type=client_credentials&client_id=XXXX&client_secret=YYYY' -H "Content-Type: application/x-www-form-urlencoded" -H "Accept: application/json"


// cURL example to generate barcode and recognize a barcode from file on the server with parameters in the request body

curl -v "https://api.aspose.cloud/v3.0/barcode/recognize?Type=Code128&ChecksumValidation=On&url=http%3A%2F%2Fwww.barcoding.com%2Fimages%2FBarcodes%2Fcode93.gif" -X POST -H "Content-Type: application/json" -H "Accept: application/json"

Response


{
  "Barcodes": [
    {
      "BarcodeValue": "AsposeBarCode",
      "BarcodeType": "Code128",
      "Region": [
        "16, 4",
        "371, 4",
        "371, 60",
        "16, 60"
      ],
      "Checksum": ""
    }
  ],
  "Code": 200,
  "Status": "OK"
}

SDKs

Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Checkout our GitHub repository for a complete list of Aspose.BarCode SDKs along with working examples, to get you started in no time.
