尽管设置 CONSUL_HTTP_TOKEN，Consul acl create 的权限仍被拒绝

Question

我用npm consul客户端。

我已将 CONSUL_HTTP_TOKEN 设置为环境变量，并尝试使用 consul.acl.create 创建令牌，但我得到 Permission denied

//code
const express = require("express");
const consul = require("consul")();

console.log('Bootstrap token is ', process.env.CONSUL_HTTP_TOKEN);

consul.acl.create((err, result) => {
  if(err) {
    console.error('found error', err);
}});

输出为：

Config.json :

{
  "acl": {
    "enabled": true,
    "default_policy": "deny",       
    "enable_token_persistence": true
  }
}

Consul 客户端包不会自动使用来自 CONSUL_HTTP_TOKEN 环境变量的 Consul 令牌。您必须明确定义一个令牌，以便在初始化 Consul 客户端或每个请求时使用。

例如：

import consul from 'consul';

// Read Consul token from environment variable
const bootstrapToken = process.env.CONSUL_HTTP_TOKEN;

// Initialize the Consul client
// Set a token to be used by default for every request
const defaultClientOptions = {
    defaults: {
        token: bootstrapToken
    }
}
const consulClient = new consul(defaultClientOptions);

// Query KV store for key 'test'
let kvQueryOptions = { key: 'test' }
consulClient.kv.get(kvQueryOptions, function (err, result) {
    if (err) throw err;

    if (!result) {
        console.log(`Key '${kvQueryOptions.key}' does not exist.`)
        return;
    }

    result.forEach(item => {
        console.log(item);
    });
});

// Query for key 'test2'
// Override the default token with a different token for this request
kvQueryOptions = {
    key: 'test2',
    token: 'C601F13E-AF45-4674-B6AB-BA50299DA0A4'
}

consulClient.kv.get(kvQueryOptions, function (err, result) { 
    if (err) throw err;

    if (!result) {
        console.log(`Key '${kvQueryOptions.key}' does not exist.`)
        return;
    }

    result.forEach(item => {
        console.log(item);
    });
});
