Using go language and Baidu translation API to translate Chinese and Czech to each other

Title: Using Go language and Baidu Translation API to achieve mutual translation between Chinese and Czech

Abstract: This article will introduce how to use Go language combined with Baidu Translation API to achieve Chinese and Czech translation Translation between Czech and other languages. We will use sample code to demonstrate how to obtain API access credentials, send translation requests, parse response results, and give a complete implementation code.

Preface

With the process of globalization, the demand for translation between different languages ​​is gradually increasing. In order to meet this demand, many machine translation service providers provide AI translation APIs in various languages, among which Baidu Translation API is one of the commonly used solutions. This article will use Go language combined with Baidu Translation API to achieve mutual translation between Chinese and Czech.

Preparation

Before we start, we need to complete the following preparations:

1. Register a Baidu Translation Open Platform account: Visit [Baidu Translation Open Platform] (http://fanyi-api.baidu.com/), register a developer account, create an application, and obtain API access credentials.
2. Install Go language environment: Visit [Go official website](https://golang.org/dl/), download and install the latest Go language version.

3. Install the necessary Go libraries: Use Go's package management tool go get to install the following two libraries:

   $ go get github.com/astaxie/beego/logs
   $ go get github.com/astaxie/beego/httplib

Sample code

The following sample code demonstrates how to use Go language and Baidu Translation API to translate Chinese and Czech to each other.

package main

import (
    "fmt"
    "github.com/astaxie/beego/httplib"
    "github.com/astaxie/beego/logs"
    "net/url"
    "strconv"
    "time"
)

const (
    API_URL     = "http://api.fanyi.baidu.com/api/trans/vip/translate"
    APP_ID      = "your_app_id"
    APP_KEY     = "your_app_key"
    FROM_LANG   = "zh"
    TO_LANG     = "cs"
)

func main() {
    logs.SetLogger(logs.AdapterConsole)

    text := "你好，世界！" //中文待翻译文本
    translation := Translate(text)
    fmt.Printf("中文翻译为捷克文: %s
", translation)

    // 为了演示完整性，进行反向翻译
    translation = Translate(translation)
    fmt.Printf("捷克文翻译为中文: %s
", translation)
}

func Translate(text string) string {
    client := httplib.Get(API_URL)
    qs := buildQueryString(text)

    client.Header("Content-Type", "application/x-www-form-urlencoded")

    response, err := client.String()
    if err != nil {
        logs.Error("Failed to get response: %v", err)
        return ""
    }

    return parseResponse(response)
}

func buildQueryString(text string) string {
    qs := url.Values{}
    qs.Add("q", text)
    qs.Add("from", FROM_LANG)
    qs.Add("to", TO_LANG)
    qs.Add("appid", APP_ID)
    qs.Add("salt", strconv.Itoa(int(time.Now().Unix())))
    sign := Sign(text, qs.Get("salt"))
    qs.Add("sign", sign)

    return qs.Encode()
}

func parseResponse(response string) string {
    // 省略解析response的代码，根据API返回结果进行处理
    // 此处只做演示，具体实现需要根据百度翻译API的返回格式进行解析
    return response
}

func Sign(text, salt string) string {
    // 省略计算签名的代码，详见百度翻译API文档
    // 这里仅作演示，实际使用时需要进行签名计算
    return text + salt
}

Notes

• Replace APP_ID and APP_KEY with the credential information obtained when you create an application on the Baidu Translation Open Platform .
• The Czech language code is "cs" and the Chinese language code is "zh". If you need to translate other languages, you need to replace FROM_LANG and TO_LANG with The corresponding language code.
• In actual development, the response results of Baidu Translation API need to be further processed, such as obtaining translation results, error handling, etc.
• According to your specific needs, it can be encapsulated into a more friendly and easy-to-use function or class.

Conclusion

This article introduces how to use Go language combined with Baidu Translation API to achieve mutual translation between Chinese and Czech. Through sample code, we demonstrate how to obtain API access credentials, send translation requests, parse response results, and provide a complete implementation code. I hope this article can help you implement more interesting language translation applications.
