使用AWS SDK加载凭据JSON导致错误

Question

我正在尝试使用loadFromPath加载AWS的凭据并获得意外错误.使用AWS.config.update对相同凭据进行硬编码工作正常.为了确保凭证文件的路径和格式是正确的,我使用fs.readFile加载它并且它正确加载,因此似乎没有任何路径/权限问题.这似乎超级基本,但我一直在努力解决我的头发.谢谢你的帮助.

错误/输出:

    Here: /home/ec2-user/.ec2/credentials.json
    Got this through readFile: { access_id: 'XXXXXXX',
    private_key: 'XXXXXXX',
    keypair: 'praneethkey',
    'key-pair-file': '/home/ec2-user/.ec2/praneethkey.pem',
    region: 'us-west-2' }

    /home/ec2-user/node_modules/aws-sdk/lib/config.js:221
    if (err) throw err;
                   ^
  SyntaxError: Unexpected token <

代码:

'use strict';

var AWS = require('aws-sdk');
var fs = require('fs');

var pathv = process.env.HOME + '/.ec2/credentials.json';

AWS.config.loadFromPath(pathv);

console.log('Here: ' + pathv);


fs.readFile(pathv, 'utf8', function (err, data) {
  if (err) {
    console.log('Error: ' + err);
    return;
  }
  data = JSON.parse(data);

console.log("Got this through readFile:",data);

您可以跳过凭据配置,如果您有env vars
AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY
AWS SDK将默认读取这些变量

如果您仍想继续从文件加载凭据,请检查credentials.json是否具有有效的JSON.

关于http://aws.amazon.com/sdkfornodejs/ 应该是这样的

{ "accessKeyId": "akid", "secretAccessKey": "secret", "region": "us-west-2" }

好像你有access_id应该是"accessKeyId"而private_key应该是"secretAccessKey"
