Linux 通过命令行解析JSON字符串

1、JSON命令：

1 2 3 4

$ wget http://stedolan.github.io/jq/download/linux32/jq (32-bit system) $ wget http://stedolan.github.io/jq/download/linux64/jq (64-bit system) $ chmod +x ./jq $ cp jq /usr/bin

2、JSON Schema：

json.txt

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

{         "name": "Google",         "location":                 {                         "street": "1600 Amphitheatre Parkway",                         "city": "Mountain View",                         "state": "California",                         "country": "US"                 },         "employees":                 [                         {                                 "name": "Michael",                                 "division": "Engineering"                         },                         {                                 "name": "Laura",                                 "division": "HR"                         },                         {                                 "name": "Elise",                                 "division": "Marketing"                         }                 ] }

3、解析JSON object：

1 2	$ cat json.txt | jq '.name' "Google"

4、解析嵌套的JSON对象: 

1 2	$ cat json.txt | jq '.location.city' "Mountain View"

5、解析JSON数组：

1 2 3 4 5

$ cat json.txt | jq '.location | {street, city}' {   "city": "Mountain View",   "street": "1600 Amphitheatre Parkway" }
