指南:获取密钥

使用密钥存储构建块安全地获取密钥

This article provides guidance on using Dapr’s secrets API in your code to leverage the secrets store building block. 密钥 API 允许您从配置的密钥存储轻松获取应用程序代码中的密钥。

建立一个密钥存储

在获取应用程序代码中的密钥之前,您必须配置一个密钥存储组件。 就本指南而言,作为一个示例,您将配置一个本地的密钥存储,该仓库使用本地的 JSON 文件来存储密钥。

注意:此示例中使用的组件未被加密且不推荐用于生产部署。 You can find other alternatives here.

创建一个名为 secrets.json 的文件,包含以下内容:

{
   "my-secret" : "I'm Batman"
}

将您的组件文件创建一个目录,名为 components ,并在其中创建一个名为 localSecretStore.yaml 的文件,并包含以下内容:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: my-secrets-store
  namespace: default
spec:
  type: secretstores.local.file
  version: v1
  metadata:
  - name: secretsFile
    value: <PATH TO SECRETS FILE>/mysecrets.json
  - name: nestedSeparator
    value: ":"

请确保用您刚刚创建的 JSON 文件的路径替换 <密钥路径>

获取密钥

现在运行 Dapr sidecar (在没有应用程序的情况下)

dapr run --app-id my-app --port 3500 --components-path ./components

现在你可以通过使用密钥 API 调用 Dapr sidecar 来获得密钥:

curl http://localhost:3500/v1.0/secrets/my-secrets-store/my-secret

从你的代码调用密钥 API

一旦您设置了一个密钥存储,您可以调用 Dapr 从您的应用程序代码中获取密钥。 以下是不同编程语言的几个示例:


import (
  "fmt"
  "net/http"
)

func main() {
  url := "http://localhost:3500/v1.0/secrets/my-secrets-store/my-secret"

  res, err := http.Get(url)
  if err != nil {
    panic(err)
  }
  defer res.Body.Close()

  body, _ := ioutil.ReadAll(res.Body)
  fmt.Println(string(body))
}

require('isomorphic-fetch');
const secretsUrl = `http://localhost:3500/v1.0/secrets`;

fetch(`${secretsUrl}/my-secrets-store/my-secret`)
        .then((response) => {
            if (!response.ok) {
                throw "Could not get secret";
            }
            return response.text();
        }).then((secret) => {
            console.log(secret);
        });

import requests as req

resp = req.get("http://localhost:3500/v1.0/secrets/my-secrets-store/my-secret")
print(resp.text)

#![deny(warnings)]
use std::{thread};

#[tokio::main]
async fn main() -> Result<(), reqwest::Error> {
    let res = reqwest::get("http://localhost:3500/v1.0/secrets/my-secrets-store/my-secret").await?;
    let body = res.text().await?;
    println!("Secret:{}", body);

    thread::park();

    Ok(())
}

var client = new HttpClient();
var response = await client.GetAsync("http://localhost:3500/v1.0/secrets/my-secrets-store/my-secret");
response.EnsureSuccessStatusCode();

string secret = await response.Content.ReadAsStringAsync();
Console.WriteLine(secret);

<?php

require_once __DIR__.'/vendor/autoload.php';

$app = \Dapr\App::create();
$app->run(function(\Dapr\SecretManager $secretManager, \Psr\Log\LoggerInterface $logger) {
    $secret = $secretManager->retrieve(secret_store: 'my-secret-store', name: 'my-secret');
    $logger->alert('got secret: {secret}', ['secret' => $secret]);
});
