当POSTing GeoJSON数据使用php时错误的请求
当POSTing GeoJSON数据使用php时错误的请求
提问于 2018-07-11 16:21:34
我有这段php代码，它将GeoJSON数据发送到一个名为AirMap的服务，以检索飞行UAS的相关规则集。
index.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
“错误请求”
index.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."}]}}我试着理解这是什么意思，但我现在只是走进了死胡同。文档(和错误代码)指出“几何”部分是必需的，这就是我添加它的原因。文档在https://developers.airmap.com/docs/rulesets上，我已经通过一个GeoJSON linter运行了GeoJSON，它通过了。

我联系了AirMap支持部门，他们帮了我大忙。因为它们需要一个额外的标志(几何体)与cURL请求一起传递，所以它们还需要一个左大括号和右大括号。因此，几何体部分将如下所示：
$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 ] ] ] }}';页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
