許益銘 rc1021

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Querying JSON with SelectToken and Linq Descendants

使用 Newtonsoft 的 SelectToken 取得 Path 節點的內容值，以及 Descendants 拜訪節點

以下的範例我們將使用這個 Json 結構進行說明

JObject o = JObject.Parse(@"{
  'Stores': [
    'Lambton Quay',
 'Willis Street'

	# Set up the request:
	apiMethod="GET"
