手写字母数字识别_Python_SDK调用(一）

通过华为Developer下载Python_SDK  (URL:https://developer.huaweicloud.com/sdk?OCR)

解压SDK压缩包

##所提供的测试代码中的信息如下所示：
  option = {}
    option["side"] = "front"
    try:
       response=ocr_client.request_ocr_service_base64("/v1.0/ocr/id-card",'./data/id-card-demo.png',option) #call OCR interface to recognize picture
       print("Status code:"+str(response.status_code)+" content:"+response.text)
    except ValueError as e:
       print(e)

根据文档中的API修改进行修改测试代码

https://support.huaweicloud.com/api-ocr/ocr_03_0032.html

try:
response=ocr_client.request_ocr_service_base64("/v1.0/ocr/handwriting",'./data/handwriting-demo.jpg',option) #call OCR interface to recognize picture
print("Status code:"+str(response.status_code)+" content:"+response.text)
except ValueError as e:
print(e)

输入结果则有异常的报错

Status code:400 content:{"error_code":"AIS.0101","error_msg":"The input parameter is invalid"}

返回检测API调用参数信息

发现在身份证识别的API接口中有有site 参数而手写字体的识别中没有site参数

重新调整代码

    option = {}
    option["text_type"] = "digit"
    try:
       response=ocr_client.request_ocr_service_base64("/v1.0/ocr/handwriting",'./data/handwriting-demo.jpg',option) #call OCR interface to recognize picture
       print("Status code:"+str(response.status_code)+" content:"+response.text)
    except ValueError as e:
       print(e)

重新执行程序则有正常输出

Status code:200 content:{"result":{"direction":-1,"words_region_count":1,"words_region_list":[{"type":"table","words_block_count":194,"words_block_list":[{"words":"","rows":[0],"columns

":[0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19]},{"words":"","rows":[1],"columns":[0]},{"words":"","rows":[1],
