从 PHP 调用 Bing 距离矩阵 - 无法读取 JSON 输入

Question

在我的应用程序中，我从 mysql 中提取数据并调用 bing 距离矩阵服务。虽然我可以使用邮递员等让电话正常工作。我尝试使用各种 cURL 方法和 unirest 的任何方法都没有成功。我回来了...

JSON input could not be read

综上所述，这就是我正在做的...

这是我正在使用的一些示例 JSON，它是 $content...

{"origins":{"latitude":"41.654570","longitude":"-71.49605"},"destinations":[{"latitude":"41.172536","longitude":"-71.555274"},{"latitude":"41.18259","longitude":"-71.567168"},{"latitude":"41.341878","longitude":"-71.695282"},{"latitude":"41.356934","longitude":"-71.63798"},{"latitude":"41.361308","longitude":"-71.625706"},{"latitude":"41.347763","longitude":"-71.67328"},{"latitude":"41.373887","longitude":"-71.665345"},{"latitude":"41.488602","longitude":"-71.38332"},{"latitude":"41.493772","longitude":"-71.137993"},{"latitude":"41.486615","longitude":"-71.246164"}],"travelMode":"driving"}

它在 JSONLint 中传递得很漂亮，也适用于邮递员。

$content 是从这个基础 $jsonbase 构建的...

$jsonbase = array(
    "origins" => [],
    "destinations" => [],
    "travelMode"   => "driving",
);

这是我从 mysql...

得到 return 后使用的位

$url = "https://dev.virtualearth.net/REST/v1/Routes/DistanceMatrix";    
$content = json_encode($jsonbase);

$headers = array('Content-Type' => 'application/json',
                'Accept' => 'application/json',
                'Content-Length' => strlen ($content),
                'key' => 'THISISMYKEY');

$body = Unirest\Request\Body::Json($jsonbase);

$response = Unirest\Request::post($url, $headers, $body);

我一定是遗漏了什么，我就是一辈子都弄不明白。在邮递员中，我有相同的 header 键设置。对于 body，我选择了原始类型和内容 JSON。任何帮助或指导将不胜感激。谢谢！

通过聊天弄明白了，问题是 API 需要 origins 和 destinations 是 lat/lng 的数组，但仔细观察结果JSON origins 不是因为它是原始数据中的单个值。

所以将单个 origin 元组放入数组中解决了这个问题，结果是 JSON:

{
    "origins": [{
        "latitude": "41.654570",
        "longitude": "-71.49605"
    }],
    "destinations": [
        {
            "latitude": "41.172536",
            "longitude": "-71.555274"
        },
        {
            "latitude": "41.18259",
            "longitude": "-71.567168"
        },
        {
            "latitude": "41.341878",
            "longitude": "-71.695282"
        },
        {
            "latitude": "41.356934",
            "longitude": "-71.63798"
        },
        {
            "latitude": "41.361308",
            "longitude": "-71.625706"
        },
        {
            "latitude": "41.347763",
            "longitude": "-71.67328"
        },
        {
            "latitude": "41.373887",
            "longitude": "-71.665345"
        },
        {
            "latitude": "41.488602",
            "longitude": "-71.38332"
        },
        {
            "latitude": "41.493772",
            "longitude": "-71.137993"
        },
        {
            "latitude": "41.486615",
            "longitude": "-71.246164"
        }
    ],
    "travelMode": "driving"
}
