Golang and Baidu AI interface: the perfect solution to build an intelligent question and answer system
Abstract:
With the continuous development of artificial intelligence technology, intelligent question and answer systems are in various has been widely used in the field. This article will introduce how to use the Golang programming language combined with Baidu AI interface to build an intelligent question and answer system, and provide relevant code examples.
Baidu AI interface provides a wealth of artificial intelligence services, including speech recognition, image recognition, natural language processing and other functions. Among them, natural language processing (NLP) involves the core capabilities of the intelligent question and answer system, and Baidu AI interface can realize these functions through API calls.
Code example:
package main import ( "fmt" "net/http" "io/ioutil" "encoding/json" ) const ( apiKey = "your apiKey" secretKey = "your secretKey" ) type ResponseData struct { ErrorCode int `json:"error_code"` ErrorMsg string `json:"error_msg"` Data struct { Answer string `json:"answer"` } `json:"data"` } func main() { question := "你叫什么名字?" url := fmt.Sprintf("http://aip.baidubce.com/rpc/2.0/unit/bot/chat?access_token=%s", getToken()) reqBody := map[string]interface{}{ "bot_session": "", "log_id": "", "request": map[string]string{ "bernard_level": "1", "client_session": `{"client_results":"", "candidate_options":[]}`, "query": question, "query_info": `{"asr_candidates":[], "source":"KEYBOARD", "type":"TEXT"}`, "updates": "", }, "bot_id": "your botId", } reqData, _ := json.Marshal(reqBody) resp, _ := http.Post(url, "application/json", bytes.NewBuffer(reqData)) defer resp.Body.Close() body, _ := ioutil.ReadAll(resp.Body) data := ResponseData{} json.Unmarshal(body, &data) if data.ErrorCode == 0 { fmt.Println("问:", question) fmt.Println("答:", data.Data.Answer) } else { fmt.Println("获取答案失败:", data.ErrorMsg) } } func getToken() string { url := fmt.Sprintf("https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=%s&client_secret=%s", apiKey, secretKey) resp, _ := http.Get(url) defer resp.Body.Close() body, _ := ioutil.ReadAll(resp.Body) data := map[string]interface{}{} json.Unmarshal(body, &data) return data["access_token"].(string) }
In the code, we first define the structure of the request and response data, and then in the main
function, build it according to the problem Requested json
data and send the request via http.Post
. Next, we parse the returned data. If the return code is 0, it means the answer is successfully obtained and the question and answer are printed out. Otherwise, it means that obtaining the answer fails and an error message is printed.
