2. 配置證書(shū)

使用如下命令配置證書(shū)：
serverless config credentials --provider aws --key AWS_ACCESS_KEY_ID --secret AWS_SECRET_ACCESS_KEY

配置完成后，會(huì)生成這個(gè)文件： ~/.aws/credentials，內(nèi)容如下：

3. 創(chuàng)建 HelloWorld

serverless create --template aws-nodejs --path hello-world

成功后會(huì)出現(xiàn)：

Serverless: Generating boilerplate...
Serverless: Generating boilerplate in "/Users/kenny/Desktop/hello-world"
 _______                             __
|   _   .-----.----.--.--.-----.----|  .-----.-----.-----.
|   |___|  -__|   _|  |  |  -__|   _|  |  -__|__ --|__ --|
|____   |_____|__|  \___/|_____|__| |__|_____|_____|_____|
|   |   |             The Serverless Application Framework

 -------'
Serverless: Successfully generated boilerplate for template: "aws-nodejs"

4. 部署 hello-world

cd hello-world && serverless deploy -v，注：這里的-v 不是顯示版本，而是 --verbose 詳細(xì)信息

成功后會(huì)出現(xiàn)：

Serverless: Packaging service...
.... 省略好多行
Service Information
service: hello-world
stage: dev
region: us-east-1
stack: hello-world-dev
resources: 5
api keys:

layers:
  None

Stack Outputs

ServerlessDeploymentBucketName: hxxx03dam9553lxq

5. 調(diào)用服務(wù)

sls invoke -f hello -l -d Kenny鍋

{
"statusCode": 200,
"body": "{
  \"message\":\"Go Serverless v1.0! Your function executed successfully!\",
  \"input\":\"Kenny鍋\"
 }"
}
--------------------------------------------------------------------
START RequestId: d1d42540-f776-4399-b39f-1742178ecec6 Version: $LATEST
END RequestId: d1d42540-f776-4399-b39f-1742178ecec6
REPORT RequestId: d1d42540-f776-4399-b39f-1742178ecec6  
Duration: 2.45 ms   Billed Duration: 100 ms     Memory Size: 1024 MB    
Max Memory Used: 72 MB

上述命令的解釋：

• sls 是 serverless 的縮寫(xiě)
• invoke 是調(diào)用服務(wù)
• -f 的 f 表示 function 名
• -l 的 l 表示 log（日志）
• -d 的 d 表示傳入的 data （數(shù)據(jù)）

更多 invoke 解釋，只需 sls invoke -h

invoke ........................ Invoke a deployed function
invoke local .................. Invoke function locally
    --function / -f (required) ......... The function name
    --stage / -s ....................... Stage of the service
    --region / -r ...................... Region of the service
    --path / -p ............ Path to JSON or YAML file holding input data
    --type / -t ........................ Type of invocation
    --log / -l ......................... Trigger logging data output
    --data / -d ........................ Input data
    --raw ...................... Flag to pass input data as a raw string

是不是很簡(jiǎn)單，行動(dòng)起來(lái)吧！

6. 是不是還有兩個(gè)文件沒(méi)講？

├── handler.js
└── serverless.yml

等您點(diǎn)贊、評(píng)論后，留著下次講 ^ _ ^
