Question

我从同一个数据库中提取了2个JSON文件，

a：）

{
    "hint_data": {
        "locations": ["AXQDAP____8AAAAABwAAABEAAAAYAAAAIwIAAERwAgAAAAAADgyCAef7TAMCAAEB", "bOsDAP____8AAAAAAwAAAAcAAADFAQAAFAAAAEJwAgAAAAAANQeCAdzdTAMFAAEB"],
        "checksum": 326195011
    },
    "route_name": ["", ""],
    "via_indices": [0, 15],
    "via_points": [
        [25.299982, 55.376873],
        [25.29874, 55.369179]
    ],
    "found_alternative": false,
    "route_summary": {
        "end_point": "",
        "start_point": "",
        "total_time": 101,
        "total_distance": 871
    },
    "route_geometry": "{_ego@m}|rhBpBaBvHuC`EuArEUtEtAlDvEnD`MlDvMli@hsEfFzn@QlTgNhwCs@fKwBjF",
    "status_message": "Found route between points",
    "status": 0
}

    ],

    "alternative_indices": [0, 183]
}

我在每个JSON文件上运行此脚本。这是脚本。

<?php
    $json       = '{"hint_data":{"locations":["AXQDAP____8AAAAABwAAABEAAAAYAAAAIwIAAERwAgAAAAAADgyCAef7TAMCAAEB","bOsDAP____8AAAAAAwAAAAcAAADFAQAAFAAAAEJwAgAAAAAANQeCAdzdTAMFAAEB"],"checksum":326195011},"route_name":["",""],"via_indices":[0,15],"via_points":[[25.299982,55.376873],[25.29874,55.369179]],"found_alternative":false,"route_summary":{"end_point":"","start_point":"","total_time":101,"total_distance":871},"route_geometry":"{_ego@m}|rhBpBaBvHuC`EuArEUtEtAlDvEnD`MlDvMli@hsEfFzn@QlTgNhwCs@fKwBjF","status_message":"Found route between points","status":0}';
    $data       = json_decode($json);
    $totalTime  = $data->route_summary->total_time;
    var_dump($totalTime);    // DUMPS     101

我正确地获得了第一个JSON文件输出，但是我在第二个中收到错误。

请告诉我JSON文件有什么问题。

Answer 1

你的json无效。

＆＃34; alternative_geometries＆＃34; property包含未正确编码的字符串。（\ x无效。如果你想要斜杠，则需要\\x）

尝试在以下位置验证：http://jsonlint.com/

Answer 2

1）将数据放入文本文件

2）再次尝试：

<?php

$data = file_get_contents('./relative/path/to/file.json');
$data = json_decode($data);
$totalTime  = $data->route_summary->total_time;
var_dump($totalTime);

最好将数据写入文件并放在某处下载以检查文件。

JSON不适用于PHP脚本
