Object Storage Service:Use Node.js to upload an object with a signed header to OSS

Overview

The Object Storage Service (OSS) software development kit (SDK) provides functions to sign, upload, and download objects. However, you may sometimes need to use the API directly to perform these actions with a signature. This topic provides a Node.js example of how to use the PutObject operation to upload an object with a signed header.

Details

The following code shows how to use the PutObject operation in Node.js v12.10.0.

var HmacSha1 = require('crypto-js/hmac-sha1') ;
var Base64 = require('crypto-js/enc-base64');
var request = require("request");
//endpoint
var endpont = 'http://oss-cn-hangzhou.aliyuncs.com';
//bucket
var bucketName = 'xxx';
//objectname
var objectname= 'mytest/nodejs.txt';
//accesskey
var accesskey = 'xxxx';
//accesskeySecret
var accesskeysecret ='xxx';



// Generate the GMT date.
var gmtDate = (new Date()).toGMTString();
console.log(gmtDate);
var contenttype = 'application/json';
var strtosgin = 'PUT\n\n'+contenttype+'\n'+gmtDate+'\n'+'/'+bucketName+'/'+objectname




var sign = Base64.stringify((HmacSha1(strtosgin,accesskeysecret)));   
   var options = {
        url: 'http://xxx.oss-cn-hangzhou.aliyuncs.com/'+objectname,
        headers: {
            'Content-Type':contenttype,
            'Date':gmtDate,
            'Authorization': 'OSS '+accesskey+':'+sign
        },
        body:'{test:test}'
    };



    request.put(options, function(error, response, body) {
        console.info('response:' + JSON.stringify(response));
        console.info("statusCode:" + response.statusCode)
        console.info('body: ' + body );
    });
