下面是提交的端到端示例ExtractBarcode请求使用JavaScript (Python)编程语言:
制作和处理LEADTOOLS CloudServices的ExtractBarcode请求结果的简单脚本。#为了运行这个脚本，需要添加以下更改:# 1)将应用程序ID放在appId变量中。# 1)向LEADTOOLS CloudServices执行一个ExtractBarcode请求。成功发出的请求将返回唯一标识符。# 2)然后我们将使用GUID查询服务——如果文件完成处理，主体将包含所有的#请求数据。# 3)我们将获取返回的json数据，解析它，并显示返回的所有信息。这个脚本使用了请求Python库。关于这个库的更多信息可以在这里找到:http://docs.python-requests.org/en/master/ import requests import sys import time servicesUrl = "https://azure.leadtools.com/api/" #应用程序ID。appId = "Replace with Application ID" #应用密码。firstPage = 1 #发送一个-1值将向服务表明文件中其余的页面应该被处理。 lastPage = -1 #A comma separated string of barcode symbologies. Passing an empty string will cause to service to use Popular by default. symbologies = "" # We will be uploading the file via a URl. Files can also be passed by adding a PostFile to the request.
