腾讯云健康码、行程卡OCR 接口封装 利用前端事件解决防疫资料信息收集

准备：1、购买腾讯云服务器（腾讯云轻量服务器 centOS），这里我选择的是已经部署了宝塔面板的。2、在文字识别控制台开通对应服务。3、在API Explorer查看健康码OCR API的示例

以下为腾讯云给到的 健康码 Python SDK

import json
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException
from tencentcloud.ocr.v20181119 import ocr_client, models
try:
    cred = credential.Credential("SecretId", "SecretKey")
    httpProfile = HttpProfile()
    httpProfile.endpoint = "ocr.tencentcloudapi.com"

    clientProfile = ClientProfile()
    clientProfile.httpProfile = httpProfile
    client = ocr_client.OcrClient(cred, "", clientProfile)

    req = models.RecognizeTravelCardOCRRequest()
    params = {

    }
    req.from_json_string(json.dumps(params))

    resp = client.RecognizeTravelCardOCR(req)
    print(resp.to_json_string())

except TencentCloudSDKException as err:
    print(err)

给到的代码不需要做太多更改，直接贴出改好后的（实际项目中用到了海外护照的OCR接口，海外护照的传入只能用base64，所以此处传入图片也用的是base64的 别问，问就是懒.....）。

登录宝塔面板，将接口文档上传到服务器，在软件商店搜索“Python项目管理”安装，点击“添加项目”配置好文件路径、Python版本、端口号及配置开机启动。

启动项目如有报错，可以在日志文档查看报错内容。

实际项目中外部提交的都是粤康码，粤康码的二维码识别后可以返回部分脱敏的明文字段，为了防止有人更改截图信息，利用二维码识别的API，将健康码OCR返回的信息与健康码二维码识别的内容进行对比，可以在一定程度上防止提交伪造的健康码
