调用方法
请参见如何调用API。
前提条件
在使用通用证件识别之前,需要您完成服务申请和认证鉴权,具体操作流程请参见开通服务和认证鉴权章节。
用户首次使用需要先申请开通。服务只需要开通一次即可,后面使用时无需再次申请。如未开通服务,调用服务时会提示ModelArts.4204报错,请在调用服务前先进入控制台开通服务,并注意开通服务区域与调用服务的区域保持一致。

请求示例
- “endpoint”即调用API的请求地址,不同服务不同区域的“endpoint”不同,具体请参见终端节点。
例如,通用证件识别服务部署在“中国-香港”区域的“endpoint”为“ocr.ap-southeast-1.myhuaweicloud.com”或“ocr.ap-southeast-1.myhuaweicloud.cn”,请求URL为“https://ocr.ap-southeast-1.myhuaweicloud.com/v2/{project_id}/ocr/id-document”,“project_id”为项目ID,获取方法请参见获取项目ID
- 如何获取Token请参见构造请求。
- 请求示例(方式一:使用图片的Base64编码)
POST https://{endpoint}/v2/{project_id}/ocr/id-document { "image" : "/9j/4AAQSkZJRgABAgEASABIAAD/4RFZRXhpZgAATU0AKgAAAA...", "country_region" : "ALB", "id_type" : "PP" }
- 请求示例(方式二:使用图片URL)
POST https://{endpoint}/v2/{project_id}/ocr/id-document { "url" : "https://BucketName.obs.xxxx.com/ObjectName", "country_region" : "ALB", "id_type" : "PP" }
响应示例
状态码: 200
成功响应示例
{ "result" : { "country_region" : "ALB", "id_type" : "PP", "side" : "front" } }
状态码: 400
失败响应示例
{ "error_code" : "AIS.0103", "error_msg" : "The image size does not meet the requirements." }
SDK代码示例
SDK代码示例如下。
使用SDK前建议将SDK更新至最新版,防止本地旧版SDK无法使用最新的OCR功能。
