How to create back-end data with json-server
This time I will show you how json-server creates back-end data, and what are the precautions for how json-server creates back-end data. The following is a practical case, let's take a look.
During the development process, the front-end and back-end are separated or not separated. The interface is mostly developed with the page later, so it is very necessary to establish a rest APL interface to provide virtual data to the front-end, so here I use json- As a tool, server supports CORS and JSONP cross-domain requests, supports GET, POST, PUT, PATCH and DELETE methods, and also provides a series of query methods, such as limit, order, etc. Next, I wrote my own usage as Document
Installation
First you must have a node environment (you must have a node environment if you use json-server) and then install json- globally server
npm install json-server -g
After the installation is completed, check whether the global installation is successful
G:\demo\JavaScript\Vue\Vue one\project\my-project\Vue_two\my-project>json-server -h index.js [options] <source> Options: --config, -c Path to config file [default: "json-server.json"] --port, -p Set port [default: 3000] --host, -H Set host [default: "0.0.0.0"] --watch, -w Watch file(s) [boolean] --routes, -r Path to routes file --middlewares, -m Paths to middleware files [array] --static, -s Set static files directory --read-only, --ro Allow only GET requests [boolean] --no-cors, --nc Disable Cross-Origin Resource Sharing [boolean] --no-gzip, --ng Disable GZIP Content-Encoding [boolean] --snapshots, -S Set snapshots directory [default: "."] --delay, -d Add delay to responses (ms) --id, -i Set database id property (e.g. _id) [default: "id"] --foreignKeySuffix, --fks Set foreign key suffix (e.g. _id as in post_id) [default: "Id"] --quiet, -q Suppress log messages from output [boolean] --help, -h Show help [boolean] --version, -v Show version number [boolean] Examples: index.js db.json index.js file.js index.js http://example.com/db.json https://github.com/typicode/json-server
Create a db.json directory in the project root directory, and then write the information
{
"api": [
{
"text": "数据统计",
"link": "#",
"hot": true
},
{
"text": "数据检测",
"link": "#",
"hot": true
},
{
"text": "流量分析",
"link": "#",
"hot": true
},
{
"text": "广告发布",
"link": "#",
"hot": false
}
]
}in package.json Add a line of commands to the scripts inside
"json": "json-server db.json --port 3003"
Execute the command in the project directory
npm run json
You will see such an interface in bash
> vue@1.0.0 json g:\demo\JavaScript\Vue\Vue one\project\my-project\Vue_two\my-project
> json-server db.json --port 3003
\{^_^}/ hi!
Loading db.json
Done
Resources
http://localhost:3003/api
Home
http://localhost:3003
Type s + enter at any time to create a snapshot of the databaseCongratulations on the successful startup!
Enter the web page for access at this time
You can access it at this time
http://localhost:3003/api
You can see the json string written before
The json-server has been started now
The calling code is like this
this.$http.get('http://localhost:3003/api')
.then((data) => {
console.log(data.body)
}, () => {
console.log('这里是用了vue-source,后端没有接口')
