Building smart applications? Come and learn the combination of Golang and Baidu AI interface!

With the rapid development of artificial intelligence technology, intelligent applications are becoming more and more common. When building intelligent applications, integration with artificial intelligence interfaces is an important link. This article will introduce how to use Golang language and Baidu AI interface to build intelligent applications.

1. Preparation work

Before starting, we need to prepare the following aspects:

• Install the Golang development environment: Golang is A powerful programming language suitable for building high-performance applications. It is open source and can support cross-platform development.
• Register Baidu Cloud account: Baidu Cloud provides a series of artificial intelligence service interfaces, such as image recognition, speech synthesis, etc. Registering a Baidu Cloud account is a prerequisite for using relevant interfaces.
• Get Baidu API Key and Secret Key: Create an application in Baidu Cloud Console and obtain the corresponding API Key and Secret Key. These keys will be used to access Baidu Cloud’s API interface.

2. Install necessary libraries

Before starting to use Golang to combine with Baidu AI interface, we need to install some necessary libraries. Use the following command to install:

go get -u github.com/ghodss/yaml go get -u github.com/go-resty/resty/v2

3. Implement the call of Baidu AI interface

First, we need to define a structure to store the results returned by Baidu AI interface:

type BaiduResponse struct { LogID int64 `json:"log_id"` ErrorMsg string `json:"error_msg"` ErrorCode int `json:"error_code"` Result interface{} `json:"result"` }

Then, we can write a function to call Baidu AI interface:

import ( "github.com/go-resty/resty/v2" "github.com/ghodss/yaml" ) func CallBaiduAPI(endpoint, apiKey, secretKey string, params interface{}, result interface{}) error { const authURL = "https://aip.baidubce.com/oauth/2.0/token" const apiURL = "https://aip.baidubce.com/rpc/2.0/unit/service/chat" // 获取AccessToken resp, err := resty.New().R(). SetFormData(map[string]string{ "grant_type": "client_credentials", "client_id": apiKey, "client_secret": secretKey, }). Post(authURL) if err != nil { return err } // 解析AccessToken type AccessToken struct { AccessToken string `json:"access_token"` } var accessToken AccessToken if err := json.Unmarshal(resp.Body(), &accessToken); err != nil { return err } // 调用百度AI接口 resp, err = resty.New().R(). SetHeader("Content-Type", "application/json"). SetQueryParams(map[string]string{ "access_token": accessToken.AccessToken, }). SetBody(params). Post(apiURL) if err != nil { return err } // 解析百度AI接口返回的结果 var baiduResp BaiduResponse if err := yaml.Unmarshal(resp.Body(), &baiduResp); err != nil { return err } // 转换为结果对象的格式 resultJSON, err := json.Marshal(baiduResp.Result) if err != nil { return err } if err := json.Unmarshal(resultJSON, result); err != nil { return err } return nil }

4. Call Baidu AI interface

For the convenience of demonstration, we use Baidu UNIT interface Take the dialogue skill as an example to show how to call Baidu AI interface.

First, we need to prepare the parameters of a dialogue request:

type ChatRequest struct { Query string `json:"query"` UserID string `json:"user_id"` } type ChatResponse struct { QuResults []struct { QuReply string `json:"qu_reply"` } `json:"qu_results"` }

Then, we can use the following code to call the Baidu AI interface:

func main() { // 准备API Key和Secret Key apiKey := "your-api-key" secretKey := "your-secret-key" // 准备百度AI接口的参数 request := ChatRequest{ Query: "你好", UserID: "user1", } var response ChatResponse // 调用百度AI接口 if err := CallBaiduAPI("unit.chat", apiKey, secretKey, request, &response); err != nil { fmt.Println("调用百度AI接口出错：", err) return } // 打印返回结果 fmt.Println("回复：", response.QuResults[0].QuReply) }

In the above code, you You need to replaceyour-api-keyandyour-secret-keywith your API Key and Secret Key respectively.

5. Summary

Through the introduction of this article, we have learned how to use Golang language and Baidu AI interface to build intelligent applications. We first completed the preparatory work, then installed the necessary libraries, then implemented the call of Baidu AI interface, and gave sample code for using Baidu UNIT interface for dialogue. I hope this article can help you understand how to combine Baidu AI interface in Golang to further build intelligent applications.
