Pass picture file parameter to specific interface location under Node.js

I have tried many other methods, but all ended in failure. The below is the only one that worked successfully.

var r = request.post('http://apicn.faceplusplus.com/detection/detect', function(err, httpResponse, body) {if (err) {return console.error('Failed:', err);};console.log('Server responded with:', body);})var form = r.form();form.append('api_key', apiKey);form.append('api_secret', apiSecret);form.append('img', fs.createReadStream('./static/generateCaptcha.png'));form.append('attribute', 'glass,pose,gender,age,race,smiling');

To let the above-mentioned code snippet work, you should firstly require two node.js modules:

var fs = require('fs');var request = require('request');

And then, you need to get your API key and API secret from the official website of the API.

The following code also works normally:

request.post({url: 'http://apicn.faceplusplus.com/detection/detect',formData: {'api_key': apiKey,'api_secret': apiSecret,'img': fs.createReadStream('./static/generateCaptcha.png'),'attribute': 'glass,pose,gender,age,race,smiling'}}, function(err, httpResponse, body) {console.log(body);});
