我正在尝试的是获取当前位置（坐标），并想将这些坐标发布到服务器上。我使用 WAMP 制作了一个服务器。我已经用java编写了php代码和代码，但它在POST单词中显示了错误。请告诉我它是否正确，或者我是否可以修改它！！
PHP代码
<?php
echo 'Hello, world!';
$json = $_GET['jsonpost'];//get the post you sent...
$data = json_decode($json); //decode the json formatted string...
print_r($data);
$id = $data->id;
$devid = $data->devid;
$latitude = $data->latitude;
$longitude = $data->longitude;
$service = $data->service;
$con = mysql_connect("","","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("a5234826_ul", $con);
$devid = $_POST['devid'];
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "devid" +$devid;
echo "latitude" + $latitude;
echo "longitude" + $longitude;
$sql = "INSERT INTO `a5234826_ul`.`locations` (
`id` ,
`devid` ,
`latitude` ,
`longitude` ,
`service`
)
VALUES (
NULL , '$devid', '$latitude', '$longitude', '$service'
)";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
mysql_close($con);
echo json_encode($variable);

我在这里看到的主要问题是 您正在谈论POST但是在您的 android LocationService 您正在创建一个HttpGet对象：
HttpGet httppost = new HttpGet("http://.../serverFile.php");
然后从无处使用 httpost 变量作为post：
post.setHeader("json",json.toString());
post.getParams().setParameter("jsonpost",postjson);
在PHP中，我不确定您想通过此实现什么：
$_SERVER['HTTP_JSON'];
因为我确定没有这样的索引。而是调用
$_POST['jsonpost']; // <-- that is the parameter name from Your JAVA code...
或
$_GET['jsonpost']; // <-- that is the parameter name from Your JAVA code...
看起来您几乎可以复制+粘贴此处类似问题中的代码（这应该是重复的！ 使用JSON数据将数据从Android发送到服务器。
编辑：好的，让我们假设您的android JAVA代码是正常的，并且您正在通过GET发送数据。然后你将不得不修复你的PHP - 试试这个：
<?php
echo 'Hello, world!';
$json = $_GET['jsonpost']; // get the json you sent through GET...
$data = json_decode($json); // decode the json formatted string...
print_r($data); // print out the $data variable to see whether everything is OK...
$devid = $data->devid;
$longitude = $data->longitude;
$latitude = $data->latitude;
$con = mysql_connect("","","") or die('Could not connect: ' . mysql_error());
mysql_select_db("a5234826_ul", $con);
echo "devid" +$devid;
echo "latitude" + $latitude;
echo "longitude" + $longitude;
$sql = "INSERT INTO `a5234826_ul`.`locations` (
`devid`,
`latitude`,
`longitude`
) VALUES (
'$Devid',
'$latitude',
'$longitude'
);";
if (!mysql_query($sql,$con)) {
die('Error: ' . mysql_error());
}
mysql_close($con);
echo json_encode($variable);
您应该继续print_r($data);，查看数据是否到达以及 JSON 是否已解码，并查看它包含哪些属性。
编辑 2 由于发布的日志猫：您是否从日志猫中读取了错误？太清楚了!!程序员当然应该理解错误消息在说什么，并且应该了解他正在做什么，而不仅仅是从某个地方复制+粘贴代码片段而不考虑它......在清单中.xml您需要添加权限READ_PHONE_STATE - 在此处阅读权限：http://developer.android.com/reference/android/Manifest.permission.html 以及在此处向清单添加权限.xml此处：http://developer.android.com/guide/topics/security/security.html#permissions。
