可以了

显示The authorization grant type is not supported是怎么回事??

func auth( apikey, secretkey string ) (string, error) {
    client := &http.Client{}
    
    v := url.Values{}
    v.Set("grant_type", "client_credentials")
    v.Add("client_id", apikey) 
    v.Add("client_secret", secretkey)
    
req, err := http.NewRequest("GET", ACCESSTOKE_URL, bytes.NewBufferString(v.Encode()))
if err != nil {
        // handle error
        return "", err
}

    resp, err := client.Do(req)
    if err != nil{
        return "", err
    }

defer resp.Body.Close()

body, err := ioutil.ReadAll(resp.Body)
if err != nil {
        return "", err
}

    fmt.Println(string(body))
    
    return string(body), nil
}

请问header里面的authorization是怎么签名?? 有没有代码分享一下????

//总是说图片格式不对。。。
func generalData() {
	cli := &http.Client{}
	accessToken := "24....874"
	url := "https://aip.baidubce.com/rest/2.0/ocr/v1/general?access_token=" + accessToken

	ff, _ := ioutil.ReadFile("z:\\mate10.png")
	str := base64.URLEncoding.EncodeToString(ff)
	str = "image=" + str
	fmt.Println(str)
	data := bytes.NewReader([]byte(str))

	req, err := http.NewRequest("POST", url, data)
	if err != nil {
		log.Fatal(err)
	}

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

	resp, err := cli.Do(req)
	if err != nil {
		log.Fatal(err)
	}

	robots, err := ioutil.ReadAll(resp.Body)
	resp.Body.Close()
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%s", robots)
}

想做个go语言的SDK

// 通用接口URL调用
func general() {
	cli := &http.Client{}
	accessToken := "24...88874"
	url := "https://aip.baidubce.com/rest/2.0/ocr/v1/general?access_token=" + accessToken

	req, err := http.NewRequest("POST", url, strings.NewReader("url=http://www-file.huawei.com/-/media/CORPORATE/Images/home/big-banner/2017/mate10-text-big-banner-cn.png?la=zh"))
	if err != nil {
		log.Fatal(err)
	}

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

	resp, err := cli.Do(req)
	if err != nil {
		log.Fatal(err)
	}

	robots, err := ioutil.ReadAll(resp.Body)
	resp.Body.Close()
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%s", robots)
}

做一下记录

分享代码？

获取client_id，client_sectet的方式见

http://ai.baidu.com/docs#/Begin/top

grant_type： 必须参数，固定为client_credentials；
client_id： 必须参数，应用的API Key；
client_secret： 必须参数，应用的Secret Key；
