# 腾讯手写识别接口转接
|
||||||
|
|
||||||
|
1. 输入图片的BASE64，返回识别结果
|
||||||
|
|
||||||
|
2. 使用JSON POST传输，返回JSON，符合restful风格
|
||||||
|
3. 入参：
|
||||||
|
- 图片的BASE64，string
|
||||||
|
- Scene：场景，默认是null，可选only_hw，string
|
||||||
|
- apikey: 测试期间，设置为固定值：1234567890，string
|
||||||
|
4. 出参：
|
||||||
|
- 识别结果，string
|
||||||
|
- 成功与否，boolean
|
||||||
|
|
||||||
|
6. 使用腾讯通用手写体识别OCR SDK进行图像识别， 使用go语言，gin框架开发；
|
||||||
|
7. 流程：
|
||||||
|
- 应用接收到POST数据以后，校验数据的合法性（json格式、base64格式等）；
|
||||||
|
- 调用腾讯通用手写体识别OCR SDK进行图像识别；
|
||||||
|
- 再调用google gemini的api进行组织语言，去除可能识别的错误。使用如下prompt：
|
||||||
|
```
|
||||||
|
你是一个专业的助手，负责纠正OCR识别结果中的文本。只需要输出识别结果，不需要输出任何解释。
|
||||||
|
```
|
||||||
|
- 返回识别结果。
|
||||||
|
|
||||||
|
8. google gemini的api key："your key"
|
||||||
|
9. tencentSecretId = "your id",tencentSecretKey = "your secret"
|
||||||
|
|
||||||
|
10. key存储在.env文件中，使用dotenv库进行加载。
|
||||||
|
11. go的示例代码如下：
|
||||||
|
|
||||||
|
```go
|
||||||

// 实例化要请求产品的client对象,clientProfile是可选的
|
||||||
|
client, _ := ocr.NewClient(credential, "", cpf)
|
||||||
|
|
||||||

// 实例化一个请求对象,每个接口都会对应一个request对象
|
||||||
|

|
||||||
|
|

|
||||||
|
request.Scene = common.StringPtr("only_hw")
|
||||||
|
|
||||||
|
// 返回的resp是一个GeneralHandwritingOCRResponse的实例，与请求对象对应
|
||||||
|
response, err := client.GeneralHandwritingOCR(request)
|
||||||
|
if _, ok := err.(*errors.TencentCloudSDKError); ok {
|
||||||
|
fmt.Printf("An API error has returned: %s", err)
|
||||||
|
return
|
||||||
|
}
|
||||||
|
if err != nil {
|
||||||
|
panic(err)
|
||||||
|
}
|
||||||
|
// 输出json格式的字符串回包
|
||||||
|
fmt.Printf("%s", response.ToJsonString())
|

}
