JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式。它基于ECMAScript的一个子集。 JSON采用完全独立于语言的文本格式,但是也使用了类似于C语言家族的习惯(包括C、C++、C#JavaJavaScriptPerlPython等)。这些特性使JSON成为理想的数据交换语言。 易于人阅读和编写,同时也易于机器解析和生成(一般用于提升网络传输速率)。

json接口如何生成?或者是如何将普通数据转化为json数据?

代码如下:

<?php
	header('content-type:application/json;charset=utf8');  
	$arr=array(  
            array(  
                "name"=>"0元大抽奖,快来体验吧", 
				"price"=>666,
				"pre_price"=>2888, 
				"dazhe"=>"3折", 
				"img"=>"img/img2.png",
				"id"=>"1001", 
                ),  
            array(  
                "name"=>"玉洁洗发水", 
				"price"=>57,
				"pre_price"=>1267, 
				"dazhe"=>"5折", 
				"img"=>"img/img4.png",
				"id"=>"1002",  
                ),  
            array(  
                "name"=>"超强微波炉", 
				"price"=>399,
				"pre_price"=>1767, 
				"dazhe"=>"7折", 
				"img"=>"img/im23.png",
				"id"=>"1003",  
                ),
            array(
            	"name"=>"柯南麻醉手表", 
				"price"=>199,
				"pre_price"=>267, 
				"dazhe"=>"6折", 
				"img"=>"img/im24.png",
				"id"=>"1004",
			),
			array(
            	"name"=>"柯达照相机", 
				"price"=>3000,
				"pre_price"=>5474, 
				"dazhe"=>"5折", 
				"img"=>"img/im25.png",
				"id"=>"1005",
			) 
        );  
  	$result=array("status"=> 1,"data"=>$arr,"msg"=>"获取商品信息成功");
    $json=json_encode($result);
	echo $json;
	

如果直接打开此文件,可以看到浏览器显示

对其进行json解析,可以看到是个完整的json格式数据

在前端用ajax请求一下:

$(function(){
			$.ajax({
				type:"get",
				url:'json.php',
				dataType:'json',
				async:true,
				success:function(res){
					//var res=JSON.parse(res);
					console.log(res);
				}
			});
		})

结果:

请求成功。
