Baidu AI interface and Golang: building a powerful question and answer system

In recent years, with the rapid development of artificial intelligence technology, people have an increasing demand for building intelligent question and answer systems. Increase. As a powerful artificial intelligence service, Baidu AI interface provides rich functions to meet the needs of various question and answer systems. As a simple and efficient programming language, Golang can provide support for us to quickly build a powerful question and answer system. This article will introduce how to use Baidu AI interface and Golang to build a powerful question and answer system, and provide corresponding code examples to help readers get started quickly.

1. Preparation

Before starting, we need to register a Baidu AI developer account and obtain the API Key and Secret Key. This information will be used in subsequent code examples. At the same time, we need to install Golang and ensure that the environment variables are set correctly.

2. Use Baidu AI interface

Baidu AI interface provides a variety of functions, including natural language processing, image recognition, speech synthesis, etc. In this article, we will focus on the question answering system part of the natural language processing interface.

The Q&A system function of Baidu AI interface is based on Baidu knowledge graph and natural language processing technology. Users can ask questions to the system through the interface and obtain corresponding answers. Next, we will demonstrate how to use Golang to call Baidu AI interface for question and answer.

First, we need to introduce the relevant Golang package:

import (
    "fmt"
    "net/http"
    "io/ioutil"
    "encoding/json"
)

Then, we define a function to send an HTTP request and get the response:

func sendRequest(url string) ([]byte, error) {
    resp, err := http.Get(url)
    if err != nil {
        return nil, err
    }
    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        return nil, err
    }
    return body, nil
}

Next, we define a Function to call the Baidu AI interface for Q&A:

func getAnswer(question string) (string, error) {
    apiKey := "YOUR_API_KEY"
    secretKey := "YOUR_SECRET_KEY"
    apiUrl := fmt.Sprintf("https://aip.baidubce.com/rpc/2.0/kg/qanda/v1/qa?access_token=%s", getAccessToken(apiKey, secretKey))
    questionUrl := fmt.Sprintf("%s&q=%s", apiUrl, question)

    body, err := sendRequest(questionUrl)
    if err != nil {
        return "", err
    }

    var result struct {
        Result []struct {
            Ans string `json:"ans"`
        } `json:"result"`
    }

    err = json.Unmarshal(body, &result)
    if err != nil {
        return "", err
    }

    if len(result.Result) > 0 {
        return result.Result[0].Ans, nil
    }

    return "", nil
}

In the above code, we use the getAccessToken function to obtain the access token required to access the Baidu AI interface. For the implementation of this function, please refer to the official documentation of Baidu AI interface.

Finally, we can call the getAnswer function in the main function to test the function of the question and answer system:

func main() {
    question := "北京的天气是多少"
    answer, err := getAnswer(question)
    if err != nil {
        fmt.Println("Error:", err)
        return
    }
    fmt.Printf("Question: %s
Answer: %s
", question, answer)
}

In the above code, we set the question to "What is the weather in Beijing", and then Call the getAnswer function to get the corresponding answer. Finally, we print out the questions and answers.

3. Summary

Through the introduction of this article, we have learned how to use Baidu AI interface and Golang to build a powerful question and answer system. Baidu AI interface provides a wealth of functions and interfaces to meet the needs of various question and answer systems. As a simple and efficient programming language, Golang can help us quickly build a powerful question and answer system. I hope this article can help readers quickly get started with Baidu AI interface and Golang, and provide some ideas and references for building their own question and answer system.
