以php为后端，vue为前端的租房微信小程序

租房微信小程序是一个非常有用的应用，它不仅可以帮助人们快速找到心仪的房屋，还可以提供便捷的房屋租赁服务。本文将介绍如何使用PHP作为后端语言和Vue作为前端框架来开发一个租房微信小程序。

1. 环境搭建

首先，需要在本地或云上安装并配置PHP和Vue环境。可以使用XAMPP、WAMP、MAMP等集成的开发环境，也可以手动安装和配置PHP环境。Vue则需要使用Node.js提供的npm包管理器进行安装和配置。

2. 创建数据库

在PHPMyAdmin或其他数据库管理工具中创建一个名为"rental"的数据库，并创建一个名为"house"的表，用于存储房屋信息。表结构如下：

| id | title | price | area | address | image | description |

3. 编写后端代码

使用PHP编写后端代码，建立与数据库连接，并提供RESTful API。代码示例：

```php

<?php

header("Access-Control-Allow-Origin: *");

header("Content-Type: application/json; charset=UTF-8");

$servername = "localhost";

$username = "root";

$password = "";

$dbname = "rental";

$conn = new mysqli($servername, $username,$password, $dbname);

if ($conn->connect_error) {

die("Connection failed: " . $conn->connect_error);

}

$method =$_SERVER['REQUEST_METHOD'];

if($method == "GET") {

$sql = "SELECT * FROM house";

$result =$conn->query($sql);

$rows = array();

if ($result->num_rows > 0) {

while($row =$result->fetch_assoc()) {

rows\[\] = row;

}

}

echo json_encode($rows);

} else if($method == "POST") {

$data = json_decode(file_get_contents("php://input"));

$title =$data->title;

$price =$data->price;

$area =$data->area;

$address =$data->address;

$image =$data->image;

$description =$data->description;

$sql = "INSERT INTO house (title, price, area, address, image, description)

VALUES ('$title', '$price', '$area', '$address', '$image', '$description')";

if ($conn-\>query($sql) === TRUE) {

echo "New record created successfully";

} else {

echo "Error: " . $sql . "\<br\>" .$conn->error;

}

}

$conn->close();

?>

```

4. 编写前端代码

使用Vue编写前端代码，实现小程序界面和数据交互。代码示例：

```html

<template>

<div class="house-list">

<div class="house" v-for="house in houses" :key="house.id">

<div class="image">

<img :src="house.image" alt="house">

</div>

<div class="info">

<h3>{{ house.title }}</h3>

<p>价格：{{ house.price }}元/月</p>

<p>面积：{{ house.area }}平米</p>

<p>地址：{{ house.address }}</p>

<p>描述：{{ house.description }}</p>

</div>

</div>

<div class="add-house">

<h3>新增房屋信息</h3>

<form @submit.prevent="submit">

<input type="text" v-model="title" placeholder="请输入标题">

<input type="number" v-model="price" placeholder="请输入价格">

<input type="number" v-model="area" placeholder="请输入面积">

<input type="text" v-model="address" placeholder="请输入地址">

<input type="text" v-model="image" placeholder="请输入图片地址">

<input type="text" v-model="description" placeholder="请输入描述">

<button type="submit">提交</button>

</form>

</div>

</div>

</template>

<script>

export default {

data() {

return {

houses: [],

title: '',

price: '',

area: '',

address: '',

image: '',

description: ''

}

},

created() {

this.getHouses()

},

methods: {

getHouses() {

fetch('http://localhost/rental/api.php')

.then(response => response.json())

.then(data => {

this.houses = data

})

},

submit() {

let data = {

title: this.title,

price: this.price,

area: this.area,

address: this.address,

image: this.image,

description: this.description

}

fetch('http://localhost/rental/api.php', {

method: 'POST',

headers: {

'Content-Type': 'application/json'

},

body: JSON.stringify(data)

})

.then(() => {

this.getHouses()

this.title = ''

this.price = ''

this.area = ''

this.address = ''

this.image = ''

this.description = ''

})

}

}

}

</script>

```

5. 运行小程序

使用微信小程序开发工具创建一个新的小程序应用，并将前端代码导入。运行小程序，观察效果。

以上就是使用PHP和Vue开发租房微信小程序的详细过程。开发者可以根据自己的需求和实际情况对代码进行修改和完善。
