Azure Face API-Node JS无法以二进制形式发送本地文件

问题描述

我尝试使用这样的配置将base64表单图像发送到Azure Face-API

var config = {
    method: 'post',url: endpoint,params: {
        returnFaceId: true,returnFaceLandmarks: false,returnFaceAttributes: 'age,gender,headPose,smile,facialHair,glasses,emotion,hair,makeup,occlusion,accessories,blur,exposure,noise'
    },body:Buffer(facesBase64,'base64'),headers: {
        'Ocp-Apim-Subscription-Key': subscriptionKey,'Content-Type': 'application/octet-stream'

    }
};

但是它总是出现错误400。我发送的二进制格式是否错误？ facesBase64已经是Base64形式。

编辑 facesBase64充满了base64这样的值

data:image/jpeg;base64,/9j/4AAQSkZJRgABAQ......

解决方法

我认为您无法将base64图像发送到Azure Face-API。

更新

将本地图像发送到faceapi。

'use strict';
const request = require('request');
const fs = require("fs");

// Replace <Subscription Key> with your valid subscription key.
const subscriptionKey = "eb8d5ea******8877c0" ;

const uriBase = 'https://pan***api.cognitiveservices.azure.com/face/v1.0/detect';

const imageBuffer = fs.readFileSync('jason.jpg');

// Request parameters.
const params = {
    'returnFaceId': 'true','returnFaceLandmarks': 'false','returnFaceAttributes': 'age,gender,headPose,smile,facialHair,glasses,' +
        'emotion,hair,makeup,occlusion,accessories,blur,exposure,noise'
};

const options = {
    uri: uriBase,qs: params,body: imageBuffer,headers: {
        'Content-Type': 'application/octet-stream','Ocp-Apim-Subscription-Key' : subscriptionKey
    }
};

request.post(options,(error,response,body) => {
    if (error) {
        console.log('Error: ',error);
        return;
    }
    let jsonResponse = JSON.stringify(JSON.parse(body),null,'  ');
    console.log('JSON Response\n');
    console.log(jsonResponse);
});

我尝试了您提到的测试方法，并得到了以下结果。

{
  "error": {
    "code": "InvalidImage","message": "Decoding error,image format unsupported."
   }
}

下面是我的测试代码。

'use strict';

//const request = require('request');
const fs = require("fs");
const axios = require("axios");
const request = require('request').defaults({ encoding: null });

// Replace <Subscription Key> with your valid subscription key.
const subscriptionKey = "eb8d5ea0********8877c0" ;

const uriBase = "https://pans***api.cognitiveservices.azure.com"+ '/face/v1.0/detect'
const imgUrl="https://pan***torage.blob.core.windows.net/ja**b/ja**.jpg";


var imageBuffer;
request.get(imgUrl,function (error,body) {
    if (!error && response.statusCode == 200) {
        var data;
        data = "data:" + response.headers["content-type"] + ";base64," + Buffer.from(body).toString('base64');
        imageBuffer=data;
        aa();
    }
});

function aa(){
// Request parameters.
const params = {
    'returnFaceId': 'true','  ');
    console.log('JSON Response\n');
    console.log(jsonResponse);
});

}

建议。

如果您真的想以这种方式实现功能，请it is recommended to raise a support on the portal。请查阅官方答案，faceapi当前支持哪种图像格式。

您还可以向官方产品组提交建议。
