1.阿里云开通人脸识别
2.以人脸属性识别为例
3.为了安全起见，我们需要搭建一个服务器，以nodejs为例
nodejs代码
var request = require('request');var url = require('url');var crypto = require('crypto');var date = new Date().toUTCString();var express = require('express');// 这里填写AK和请求var ak_id = '你的ak';var ak_secret = '你的ak_secret';var app = express();//人脸属性识别function getFaceAttribute(obj,getMsg){ var options = { //这里调用的是人脸属性识别接口 url : 'https://dtplus-cn-shanghai.data.aliyuncs.com/face/attribute', method: 'POST', body:obj,//这里传递参数 headers: { 'accept': 'application/json', 'content-type': 'application/json', 'date': date, 'Authorization': '' } }; md5 = function(buffer) { var hash; hash = crypto.createHash('md5'); hash.update(buffer); return hash.digest('base64'); }; sha1 = function(stringToSign, secret) { var signature; return signature = crypto.createHmac('sha1', secret).update(stringToSign).digest().toString('base64'); }; // step1: 组stringToSign [StringToSign = #{method}\\n#{accept}\\n#{data}\\n#{contentType}\\n#{date}\\n#{action}] var body = options.body || ''; var bodymd5; if(body === void 0 || body === ''){ bodymd5 = body; } else { bodymd5 = md5(new Buffer(body)); } console.log(bodymd5) var stringToSign = options.method + "\n" + options.headers.accept + "\n" + bodymd5 + "\n" + options.headers['content-type'] + "\n" + options.headers.date + "\n" + url.parse(options.url).path; console.log("step1-Sign string:", stringToSign); // step2: 加密 [Signature = Base64( HMAC-SHA1( AccessSecret, UTF-8-Encoding-Of(StringToSign) ) )] var signature = sha1(stringToSign, ak_secret); // console.log("step2-signature:", signature); // step3: 组authorization header [Authorization = Dataplus AccessKeyId + ":" + Signature] var authHeader = "Dataplus " + ak_id + ":" + signature; console.log("step3-authorization Header:", authHeader); options.headers.Authorization = authHeader; console.log('authHeader', authHeader); // step4: send request /*if (error) { console.log("error", error) } console.log("step4-response body:", response.statusCode, body)*/ function callback(error, response, body) { getMsg(error,response,body); } request(options, callback);}//设置跨域访问app.all('*', function(req, res, next) { res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "X-Requested-With"); res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS"); res.header("X-Powered-By",' 3.2.1') res.header("Content-Type", "application/json;charset=utf-8"); next();});app.get('/face/getFaceAttribute', function(req, res) { getFaceAttribute('{image_url:"'+req.query.image_url+'"}',function(error,response,body){ if (error) { console.log("error", error) } console.log("step4-response body:", response.statusCode, body) res.end(JSON.stringify(body)); });});app.listen(8888);console.log("port at 8888");
如果在本地运行此nodejs的话，地址是127.0.0.1:8888/face/getFaceAttribute
请求方式是get
这个时候前端页面只需要调用这个ajax地址就好了
$.ajax({ type:"get", url:"http://127.0.0.1:8888/face/getFaceAttribute",//服务器我是部署在本地 async:true, data:{'image_url':'www.yuanyizheng.com/fuzi.jpg'}, success:function(data){ console.log('success'); console.log(data); }, error:function(data){ console.log('error') console.log(data); }});
