php - 使用 php 发布 GeoJSON 数据时出现错误请求

问题描述

我有这个 php 代码，它将 GeoJSON 数据发布到名为 AirMap 的服务，以检索飞行 UAS 的相关规则集。

索引.php

<?
$ch = curl_init();

$json_data = '"geometry":' + '{ "type": "Polygon",
    "coordinates": [
      [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ]
      ]
   }';

curl_setopt($ch, CURLOPT_URL, "https://api.airmap.com/rules/v1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$'{");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data); 

$headers = array();
$headers[] = "X-Api-Key: (removed)";
$headers[] = "Content-Type: application/json; charset=utf-8";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);


$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

echo "$result";
?>

每当我执行此代码时，页面都会显示

“错误的请求”

索引.php 2

<?
$ch = curl_init();

$json_data = '{ "type": "Polygon",
    "coordinates": [
      [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ]
      ]
   }';

curl_setopt($ch, CURLOPT_URL, "https://api.airmap.com/rules/v1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$'{");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data); 

$headers = array();
$headers[] = "X-Api-Key: (removed)";
$headers[] = "Content-Type: application/json; charset=utf-8";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);


$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

echo "$result";
?>

每当我执行该代码时，它都会显示

{"status":"fail","data":{"message":"parameter validation failed","data":[{"name":"geometry","message":"Invalid param"},{"name":"geometry","message":"A valid geometry must be included."},{"name":"type","message":"Parameter not allowed."},{"name":"coordinates","message":"Parameter not allowed."}]}}

我试图理解这意味着什么，但我目前处于死胡同。文档（和错误代码）说“几何”部分是必需的，所以这就是我添加它的原因。该文档位于https://developers.airmap.com/docs/rulesets，我已经通过 GeoJSON linter 运行了 GeoJSON，并且它通过了。

解决方案

我联系了 AirMap 支持，他们帮助了我。由于它们需要与 cURL 请求一起传递的附加标志（几何），因此它们还需要打开和关闭大括号。所以几何部分看起来像这样：

$json_data2 = '{"geometry": { "type": "Polygon", "coordinates": [ [ [ -118.37099075317383, 33.85505651142062 ], [ -118.37305068969727, 33.85502978214579 ], [ -118.37347984313963, 33.854673391015496 ], [ -118.37306141853333, 33.85231226221667 ], [ -118.37193489074707, 33.85174201755203 ], [ -118.36997151374815, 33.85176874785573 ], [ -118.36995005607605, 33.8528112231754 ], [ -118.37099075317383, 33.85505651142062 ] ] ] }}';
