七牛 OCR 接口调试 & 七牛鉴权 Token 应用
在参考七牛官方接口的基础上，提供 PHP/Java/Python/Go 语言的实现以及执行结果。此外：
- 代码基于各服务端语言的七牛 SDK
- 【重要】七牛其他使用鉴权 token的接口，和此接口调用方式类似。如内容审核的7个接口，人脸识别3个接口，以图搜图等。具体实现可以参考下文的【现学现卖】图片内容审核接口
- 下面的代码主要提供接入的参考思路，建议根据需要，调试成功后再修改集成到自己的代码中
接口规约
POST /v1/ocr/idcard Http/1.1
HOST: ai.qiniuapi.com
Content-Type:application/json
Authorization: Qiniu <AccessKey>:<Sign>
{
"data": {
"uri": "http://oayjpradp.bkt.clouddn.com/age_gender_test.png"
}
}
PHP 实现
核心代码
// 鉴权凭证
$url = "http://ai.qiniuapi.com/v1/ocr/idcard";
$method = "POST";
$host = "ai.qiniuapi.com";
$body = "{ \"data\": { \"uri\": \"http://test-pub.iamlj.com/test-idcard.jpg\" } }";
$contentType = "application/json";
$headers = $auth->authorizationV2($url, $method, $body, $contentType);
$headers['Content-Type'] = $contentType;
$headers['Host'] = $host;
$response = Client::post($url, $body, $headers);
执行结果
源代码
Java 实现
核心代码
String url = "http://ai.qiniuapi.com/v1/ocr/idcard";
String host = "ai.qiniuapi.com";
String body = "{ \"data\": { \"uri\": \"http://test-pub.iamlj.com/test-idcard.jpg\" } }";
String contentType = "application/json";
String method = "POST";
String qiniuToken = "Qiniu " + auth.signRequestV2(url, method, body.getBytes(), contentType);
System.out.println(url);
System.out.println(body);
System.out.println(qiniuToken);
StringMap header = new StringMap();
header.put("Host", host);
header.put("Authorization", qiniuToken);
header.put("Content-Type", contentType);
Configuration c = new Configuration(Zone.zone1());
Client client = new Client(c);
Response response = client.post(url, body.getBytes(), header, contentType);

【现学现卖】图片内容审核接口
实现图片内容审核，参考 OCR demo 的代码文件，只需要修改请求 url 和 body，即可调用成功，具体如下：
接口规约
POST /v3/image/censor HTTP/1.1 Host: ai.qiniuapi.com
Content-Type: application/json
Authorization: Qiniu YnxrxOSvGotRZpqkZnMzl_euuoqRzOKUd6zwbRju:r6a-o2UpBg6A4puIMnkCExH8lE8=核心代码
String url = "http://ai.qiniuapi.com/v3/image/censor"; String host = "ai.qiniuapi.com";
String body = "{ \"data\": { \"uri\": \"https://mars-assets.qnssl.com/resource/gogopher.jpg\" }, \"params\": { \"scenes\": [ \"pulp\", \"terror\", \"politician\" ] } }";
String contentType = "application/json";
String method = "POST";
String qiniuToken = "Qiniu " + auth.signRequestV2(url, method, body.getBytes(), contentType);
System.out.println(url);
System.out.println(body);
System.out.println(qiniuToken);
StringMap header = new StringMap();
header.put("Host", host);
header.put("Authorization", qiniuToken);
header.put("Content-Type", contentType);
Configuration c = new Configuration(Zone.zone1());
Client client = new Client(c);
Response response = client.post(url, body.getBytes(), header, contentType);执行结果
代码
Python 实现
核心代码
url = 'http://ai.qiniuapi.com/v1/ocr/idcard'
data = {"data": {"uri": "http://test-pub.iamlj.com/test-idcard.jpg"}}
req = http._post_with_qiniu_mac(url, data, auth)
执行结果
源代码
Go 实现
核心代码
url := "http://ai.qiniuapi.com/v1/ocr/idcard"
method := "POST"
host := "ai.qiniuapi.com"
contentType := "application/json"
bodyUri := OcrIdcardData{Uri: "http://test-pub.iamlj.com/test-idcard.jpg"}
body := OcrIdcard{Data: &bodyUri}
reqData, _ := json.Marshal(body)
req, reqErr := http.NewRequest(method, url, bytes.NewReader(reqData))
if reqErr != nil {
return
}
req.Header.Add("Content-Type", contentType)
req.Header.Add("Host", host)
qiniuToken, signErr := mac.SignRequestV2(req)
if signErr != nil {
fmt.Printf(signErr.Error())
}
req.Header.Add("Authorization", "Qiniu "+qiniuToken)
fmt.Println(string(url))
fmt.Println(string(reqData))
fmt.Println(string("Qiniu " + qiniuToken))
resp, respErr := http.DefaultClient.Do(req)
if respErr != nil {
