我正在尝试使用坐标检索用户的城市信息。有一个javascript函数,它采用纬度/经度并将其发送到带有ajax的php文件:
Javascript功能
if (navigator.geolocation) { //Checks if browser supports geolocation
var Clatitude = "no";
var Clongitude;
navigator.geolocation.getCurrentPosition(function(position) {
Clatitude = position.coords.latitude;
Clongitude = position.coords.longitude;
$.ajax({
type: "POST",
url: "../wp-content/themes/Avada-child/test_BLZ.php",
data: {'latitudine': Clatitude,'longitudine': Clongitude},
success: function(data) {
console.log(data);
},
dataType: "JSON"
});
},
function(error) {
alert(error.message);
}, {
enableHighAccuracy: true,
timeout: 5000
});
}
用PHP编写的服务器端脚本
<?php
$latitudine = $_POST['latitudine'];
$longitudine = $_POST['longitudine'];
$geolocation = $latitudine.','.$longitudine;
$request = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.$geolocation.'&sensor=false';
$file_contents = url_get_contents($request);
echo ($file_contents);
function url_get_contents ($Url) {
if (!function_exists('curl_init')){
die('CURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $Url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
?>
问题是我的控制台中没有显示响应。我尝试使用file_get_contents
进行回复,但仍然无法检索回复
除此之外,其余代码工作正常。实际上,只要我从php文件中删除curl's
内容或file_get_contents
,其余代码就会顺利运行。我甚至设法在ajax成功函数中检索(假)响应。
有人可以帮忙吗?谢谢;)
---编辑 我的curl执行时间很长,我在另一台服务器上运行相同的代码,这些是差异:

我的服务器有什么问题?我注意到在第一种情况下没有ip引用!
答案 0 :(得分:-1)
由于您的服务器响应不是JSON
,因此您不应该从dataType:"JSON"
来电设置AJAX
。
请从AJAX
来电评论。
$.ajax({
type: "POST",
url: "../wp-content/themes/Avada-child/test_BLZ.php",
data: {'latitudine': Clatitude,'longitudine': Clongitude},
success: function(data) {
console.log(data);
},
//dataType: "JSON" <-- COMMENT this out
});
或强>
另一个选择是您应该从服务器发送JSON
编码的响应。
$file_contents = url_get_contents($request);
echo (json_encode($file_contents));
