modify json response in php?

本文关键字：json 响应修改 php | 更新日期: 2023-09-27

我是php新手，为我的颜色响应创建web服务。它在我的web应用程序上工作得很好，因为我可以很容易地从它中获取数据，现在在android m卡住了。

我有这样的反应。

{
        "#CCCCCC":[43.2,"SILVER"], 
        "#424153":[42.6,"GREY"],
        "#999999":[13.7,"LIGHT GREY"]
}

我想把这个改成那样。

{
   "colors":
            [
               {
                 "hex" : "#CCCCCC",
                 "percentgae" : "43.2",
                 "name" : "silver"
               },
               {
                 "hex" : "#424153",
                 "percentgae" : "43.2",
                 "name" : "grey"
               },
               {
                 "hex" : "#999999",
                 "percentgae" : "13.2",
                 "name" : "light grey"
               }
            ]
}

你能告诉我怎么做吗?

谢谢。

可以使用下一个函数

<?php
function format($json) {
    $colors = json_decode($json);
    $result = [];
    foreach ($colors as $color => $attributes) {
        $result[] = [
            'hex'         => $color,
            'percentagae' => $attributes[0],
            'name'        => $attributes[1]
        ];
    }
    return json_encode([ 'colors' => $result]);
}
$json        = '{ "#CCCCCC":[43.2,"SILVER"], "#424153":[42.6,"GREY"], "#999999":[13.7,"LIGHT GREY"] }';
$expectation = '{"colors":[{"hex":"#CCCCCC","percentagae":43.2,"name":"SILVER"},{"hex":"#424153","percentagae":42.6,"name":"GREY"},{"hex":"#999999","percentagae":13.7,"name":"LIGHT GREY"}]}';
$response    = format($json);
if ($response != $expectation) {
    throw new Exception('FAIL');
}
echo 'SUCCESS';
