Json-server Analog Rest API

In general, an app's data needs to wait for the interface personnel to develop the corresponding interface can be obtained, so the efficiency is a bit low. It is best that we can simulate the interface data by ourselves, fill the data of the page, get through all the joints, and then develop the interface, and change the interface address.

The tool we're going to talk about today:Json-server can do that.

1, installation Json-server

First of all our computers are installed with Nodejs, and then use the NPM command to install:sudo npm install-g json-server

mewifi:~ cjy$ npm install-g json-server/usr/local/bin/json-server-/usr/local/lib/node_modules/json-server/bin/ index.js-[email protected] node_modules/json-server/node_modules/compression/node_modules/ms/usr/local/lib└─┬[ Email protected]   ├─┬[email protected]   │├──[email protected]   │└──[email protected]   ├──[email Protect ED]   ├─┬[email protected]   │└─┬[email protected]   │   └──[email protected]   ├──[email protected]    ├─┬[email protected]  │└─┬[email protected]  │   └─┬[email protected]  │     └─┬[email Protected]  │       └─┬[email protected]   │         └──[email protected]   └─┬[email protected]    └─┬[ Email protected]      └─┬[email protected]        └─┬[email protected]           

Verify that the installation is successful, view the Json-server configuration entry:json-server-h

2. Operation

Create a JSON file in any directory, such as creating a Data.json file in the JSON directory, writing the following, and executing json-server in the JSON directory Data.json

{"    list": {        "news": [            {
"NewsId": 1,                "title": "Title 1",                "content": "Chef Crying"            },            {
"NewsId": 2,                "title": "Heading 2",                "content": "How Could"            }        ]    },    "detail": {        "object": {            "Name": "I am a sledgehammer",            "sex": 1,            "Iscomplete": True        }}    }

If you succeed, you will see something like this

mewifi:~ cjy$ CD/work/json/mewifi:json cjy$ json-server data.json  \{^_^}/  hi! Loading Data.json  done  Resources  http://localhost:3000/list  http://localhost:3000/detail  Home  http://localhost:3000  Type s + Enter at any time to create a snapshot of the database

Next, you will be able to access:

3. Common operation

Json-server supports GET, POST, PUT, PATCH, and DELETE methods, and provides a range of query methods, such as Limit,order.

Here is the main introduction of its powerful filtering function .

Sample Data Source:

[    {        "newsId": 1,        "title": "Heading 1",        "content": "Chef Crying"    },    {        "newsId": 2,        "title": "Title 2",        "content": "How Can"    }]

Property value (Filter)

Using . Action object property values

Get content with a length of 4 data

Sorting (sort)

Use _sort and _order (default use Ascending (ASC))

Sort in descending order of NewSID

Split (Slice)

Use _start and _end or _limit

Get 1 data starting from subscript 0 (first object)

Full Text Search

Use q to traverse the object in all value to find the data that contains the specified value

Find all fields that contain "possible" data

Use _likePerform fuzzy lookups (regular expressions are supported)

Find data that contains the words "crying" in content
