PHP three lines of code to write test interface

Why does front-end development have to wait for interfaces every time . Isn't it fragrant to write one by yourself .

mock Local analog data idle trouble ,postman Writing interfaces is also troublesome .

Of course , Here I mean novice , Like to pursue simple and rough ways .

In fact, the essence of an interface is to return a string json object , So the simplest thing is ：

One .json Text

1. Build a local environment , It can be phpstydy Integrate , It can also be wamp Integrate . Can provide web The service can be .

Such as lz utilize phpstudy Integrated local services

2. Create a test.json Text , It says what you want to return json data format .

as follows ：json Don't be wrong about the format

3. And then visit locally ：http://localhost:8080/test.json You can see the following effect ：

The data looks like the correct back-end return data ,http://localhost:8080/test.json Is the request address , So can we go through ajax Where is the request ？

I'm sorry , I never tried. . I'm not sure .

A little off topic . Get down to business 、

Two .php Three lines of code simple interface

1. This step and json The text is the same , First set up local web Environmental Science

2. Create a test.php file

3. The following code must be written to allow cross domain .

<?php
    header('Content-Type: text/html;charset=utf-8');
   	header('Access-Control-Allow-Origin:*'); // * Delegate allows any URL request 
  	header('Access-Control-Allow-Methods:POST,GET,OPTIONS,DELETE'); //  The type of request allowed 
   	header('Access-Control-Allow-Credentials: true'); //  Set whether to allow sending  cookies
	header('Access-Control-Allow-Headers:x-requested-with,content-type');
	header("Content-Type: text/html; charset=utf-8");
	header('Content-Type:application/json; charset=utf-8');?>

Here comes the key three lines of code

$json='{"all_rank_list": [{"area": " Huangyan District ","all_value": "7.3"},{"area": " Jiaojiang District ","all_value": "5.3"}]}';
    $arr=json_decode($json,true);
	echo json_encode($arr);

That's it , Access address http://localhost:8080/test.php You can return the corresponding json Data. . It can be used as the interface request address
