json-server使用

作為一個前端開發工程師,在後端還沒有ready的時候,不可避免的要使用mock的資料。很多時候,我們並不想使用簡單的靜
態資料,而是希望自己起一個本地的mock-server來完全模擬請求以及請求回來的過程。json-server是一個很好的可以替
我們完成這一工作的工具。
1、安裝
cnpm i json-server -g
2、新建資料檔案(我建立的是一個api檔案)
3、啟動json-server
json-server api/city.json
因為我json檔案裡面有兩個物件`
{
"list": [
{
"id" : 1,
"title": "bim專案啟動了",
"date": "2018-08-12",
"likes": 33,
"views": 124
},
{
"id": 2,
"title": "bim專案啟動了",
"date": "2018-08-12",
"likes" : 5554,
"views": 212
}
],
"comments": [
{
"id": 1,
"news_id": 1,
"data": [
{
"id": 1,
"content": "測試資料"
},
{
"id": 2,
"content" : "測試資料"
}
]
},
{
"name": "pyl",
"id": 2
}
]
}
`所以就生成了2個介面。
看見就基本成功了,接下來就是呼叫介面了
methods: {
json_getdata(params) {
return axios({
method: "get",
url: "http://localhost:3000/list",
params:{}
})
},
async getdata(){
const {data} = await this.json_getdata()
console.log(data);
}
},
完成!!
post/patch等等查詢只放程式碼 不放結果了,截圖太費勁了,浪費時間~
post
json_postdata(data) {
return axios({
method: "post",
url: "http://localhost:3000/list",
data: {
title: "bim專案啟動了",
date: new Date(),
},
});
},
async postdata() {
const { data } = await this.json_postdata();
console.log(data);
},
patch
json_patchdata(id) {
return axios({
method: "patch",
url: "http://localhost:3000/list/3",
data: {
title: "我叫南京黑馬潘奕霖",
},
});
},
async patchdata() {
const { data } = await this.json_patchdata();
console.log(data);
},
delete懶得寫了 也就那麼回事
附上完整程式碼
<template>
<div class="home">
<button @click="getdata">getdata</button>
<button @click="postdata">post</button>
<button @click="patchdata">patch</button>
<button>delete</button>
</div>
</template>
<script>
// @ is an alias to /src
import axios from "axios";
export default {
name: "Home",
data() {
return {
// num: 123
};
},
methods: {
json_patchdata(id) {
return axios({
method: "patch",
url: "http://localhost:3000/list/3",
data: {
title: "我叫南京黑馬潘10",
},
});
},
async patchdata() {
const { data } = await this.json_patchdata();
console.log(data);
},
json_getdata(params) {
return axios({
method: "get",
url: "http://localhost:3000/list",
params: {},
});
},
async getdata() {
const { data } = await this.json_getdata();
console.log(data);
},
json_postdata(data) {
return axios({
method: "post",
url: "http://localhost:3000/list",
data: {
title: "bim專案啟動了",
date: new Date(),
},
});
},
async postdata() {
const { data } = await this.json_postdata();
console.log(data);
},
},
};
</script>
