Golang多语言检测与批量识别API插件库detectlanguage的使用

Detect Language API Go客户端用于检测给定文本的语言，返回检测到的语言代码和置信度分数。

安装

go get -u github.com/detectlanguage/detectlanguage-go

配置

使用前需要设置您的个人API密钥，可以在官网注册获取。

client := detectlanguage.New("YOUR API KEY")

使用示例

语言检测

// 检测单个文本的语言
detections, err := client.Detect("Buenos dias señor")

if err != nil {
    fmt.Fprintln(os.Stderr, "error detecting language:", err)
    os.Exit(1)
    return
}

fmt.Fprintln(os.Stdout, "Language:", detections[0].Language)     // 检测到的语言代码
fmt.Fprintln(os.Stdout, "Reliable:", detections[0].Reliable)     // 是否可靠
fmt.Fprintln(os.Stdout, "Confidence:", detections[0].Confidence) // 置信度分数

单语言代码检测

// 只获取语言代码
language, err := client.DetectCode("Buenos dias señor")

if err != nil {
    fmt.Fprintln(os.Stderr, "error detecting language:", err)
    os.Exit(1)
    return
}

fmt.Fprintln(os.Stdout, "Language:", language)

批量检测

// 批量检测多个文本
texts := []string{"labas rytas", "good morning"}
results, err := client.DetectBatch(texts)

if err != nil {
    fmt.Fprintln(os.Stderr, "error detecting language:", err)
    os.Exit(1)
    return
}

fmt.Fprintln(os.Stdout, "First text language:", detections[0][0].Language)
fmt.Fprintln(os.Stdout, "Second text language:", detections[1][0].Language)

获取账户状态

// 查询账户使用情况
result, err := client.UserStatus()

if err != nil {
    fmt.Fprintln(os.Stderr, "error getting user status:", err)
    os.Exit(1)
    return
}

fmt.Fprintln(os.Stdout, "Status:", result.Status)
fmt.Fprintln(os.Stdout, "Requests sent today:", result.Requests)
fmt.Fprintln(os.Stdout, "Bytes sent today:", result.Bytes)
fmt.Fprintln(os.Stdout, "Plan:", result.Plan)
fmt.Fprintln(os.Stdout, "Plan expires:", result.PlanExpires)
fmt.Fprintln(os.Stdout, "Daily requests limit:", result.DailyRequestsLimit)
fmt.Fprintln(os.Stdout, "Daily bytes limit:", result.DailyBytesLimit)
fmt.Fprintln(os.Stdout, "Date:", result.Date)

获取支持的语言列表

// 查询支持的所有语言
languages, err := client.Languages()

if err != nil {
    fmt.Fprintln(os.Stderr, "error getting languages list:", err)
    os.Exit(1)
    return
}

fmt.Fprintln(os.Stdout, "Supported languages:", len(languages))
fmt.Fprintln(os.Stdout, "First language code:", languages[0].Code)
fmt.Fprintln(os.Stdout, "First language name:", languages[0].Name)
