Types

type Client

type Client struct {
	APIKey            string `env:"BAIDU_API_KEY"`
	SecretKey         string `env:"BAIDU_SECRET_KEY"`
	AccessToken       string
	AccessTokenExpire int64 // access token过期时间戳
}

var Baidu *Client

百度客户端，必须先调用Init或InitEnv初始化

func Init

func Init(api, secret string) (*Client, error)

Init 初始化百度客户端

func InitEnv

func InitEnv() (*Client, error)

InitEnv 初始化百度客户端 使用环境变量

func (*Client) GetAccessToken

func (b *Client) GetAccessToken() (string, error)

GetAccessToken 获取access token https://ai.baidu.com/ai-doc/REFERENCE/Ck3dwjhhu

func (*Client) OCR

func (b *Client) OCR(image string) (*OCRResult, error)

OCR 通用文字识别 https://ai.baidu.com/ai-doc/OCR/vk3h7y58v

type Location

type Location struct {
	Top    uint32 `json:"top"`
	Left   uint32 `json:"left"`
	Width  uint32 `json:"width"`
	Height uint32 `json:"height"`
}

type OCRResult

type OCRResult struct {
	LogID          uint64        `json:"log_id"`
	WordsResultNum uint32        `json:"words_result_num"`
	WordsResult    []WordsResult `json:"words_result"`
	ErrorCode      int           `json:"error_code"` // 错误码
	ErrorMsg       string        `json:"error_msg"`  // 错误描述
}

type TokenError

type TokenError struct {
	Error            string `json:"error"`             // 错误类型
