Golang connects to Baidu AI interface to realize ID card recognition function and gets started quickly

Preface
With the development of artificial intelligence, AI interfaces are increasingly used in various fields. coming more and more widely. Baidu AI open platform provides a rich AI interface and provides developers with a convenient way to implement various functions. This article will introduce how to use Golang to connect to Baidu AI interface to realize the ID card recognition function.

1. Register a Baidu AI Open Platform Account
First, we need to register an account on the Baidu AI Open Platform and create an application. Open the official website of Baidu AI Open Platform (https://ai.baidu.com/) and click the "Register Now" button in the upper right corner. Follow the prompts on the page to fill in the relevant information and create an account.

2. Create an application and obtain API Key and Secret Key
After successfully logging in, click the "Console" button in the upper right corner to enter the personal console page. Find "My Apps" in the left navigation bar and click to enter. Click "Create Application" in the application list, fill in the application name, application description and other information as prompted, and submit.

After the creation is successful, click the application name to enter the application details page. On this page you can see the API Key and Secret Key, which will be used in the following code.

3. Install Baidu AI Go SDK
Before starting to write code, we need to install Baidu AI Go SDK. Use the following command to install:

go get github.com/AcidGo/baiduai-sdk

4. Write a program to identify ID cards
First, we need to import the required packages:

import (
    "fmt"
    "github.com/AcidGo/baiduai-sdk"
)

In the main function, we need to set the API Key and Secret Key:

func main() {
    APP_ID := "your_app_id"
    API_KEY := "your_api_key"
    SECRET_KEY := "your_secret_key"

    client := baiduai.NewClient(API_KEY, SECRET_KEY)
    client.SetAppID(APP_ID)

    // ...
}

Next, we need to call the Baidu AI interface to identify the ID card. We can achieve this by calling the client.IDCard(imageUrl) method. For example:

imageUrl := "http://example.com/id_card.jpg"
result, err := client.IDCard(imageUrl)
if err != nil {
    fmt.Println("识别失败：", err)
} else {
    fmt.Printf("识别成功：%+v
", result)
}

where imageUrl is the URL of the ID card image you want to identify. If the recognition is successful, result will contain information about each field of the ID card.

5. Complete sample code

package main

import (
    "fmt"
    "github.com/AcidGo/baiduai-sdk"
)

func main() {
    // 设置API Key和Secret Key
    APP_ID := "your_app_id"
    API_KEY := "your_api_key"
    SECRET_KEY := "your_secret_key"

    client := baiduai.NewClient(API_KEY, SECRET_KEY)
    client.SetAppID(APP_ID)

    // 调用识别身份证接口
    imageUrl := "http://example.com/id_card.jpg"
    result, err := client.IDCard(imageUrl)
    if err != nil {
        fmt.Println("识别失败：", err)
    } else {
        fmt.Printf("识别成功：%+v
", result)
    }
}

6. Summary
Through the introduction of this article, we have learned how to use Golang to connect to Baidu AI interface to realize the ID card recognition function. First, we registered a Baidu AI open platform account and created an application. Then, use Baidu AI Go SDK to access the interface and call the function of identifying ID cards. Finally, we wrote a sample program to identify the ID card by calling the interface.

I hope this article can help you learn and understand Golang's connection with Baidu AI interface. You are welcome to consult the official documentation of Baidu AI open platform and the documentation of Go SDK for further in-depth study and exploration. I wish everyone will go further and further on the road of AI development!
