我正在使用Ionic开发移动应用程序。当我尝试从mysql中选择数据时,它可以在我的浏览器中运行,但是当我使用外部服务器时,它不起作用(在我的手机上)! 有人可以帮助我:
ExtractData.php:
<?php
header("Access-Control-Allow-Origin: *");
$request=json_decode(file_get_contents("php://input"));
$con=mysql_connect("","","") ;//or die(mysql_error());
mysql_select_db("myDbB",$con);
$qry_em_1 = "SELECT id,matricule,idTransporteur FROM camion";
$qry_em_2 = "SELECT id,matricule FROM bateau";
$qry_em_3 = "SELECT id,codeTransporteur FROM transporteur";
$qry_em_4 = "SELECT id,designation FROM trajet";
$qry_em_5 = "SELECT id,codeFr FROM fournisseur";
$qry_em_6 = "SELECT codeArticle,description FROM article";
$qry_em_7 = "SELECT id,description FROM moyenTransport";
$result_1 = mysql_query($qry_em_1) or die('Could not query');
$result_2 = mysql_query($qry_em_2) or die('Could not query');
$result_3 = mysql_query($qry_em_3) or die('Could not query');
$result_4 = mysql_query($qry_em_4) or die('Could not query');
$result_5 = mysql_query($qry_em_5) or die('Could not query');
$result_6 = mysql_query($qry_em_6) or die('Could not query');
$result_7 = mysql_query($qry_em_7) or die('Could not query');
//encode camion data
if(mysql_num_rows($result_1)){
echo '{"camion":[';
$first = true;
while($row=mysql_fetch_row($result_1)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode bateau data
if(mysql_num_rows($result_2)){
echo '"bateau":[';
$first = true;
while($row=mysql_fetch_row($result_2)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode transporteur data
if(mysql_num_rows($result_3)){
echo '"transporteur":[';
$first = true;
while($row=mysql_fetch_row($result_3)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode trajet data
if(mysql_num_rows($result_4)){
echo '"trajet":[';
$first = true;
while($row=mysql_fetch_row($result_4)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode fournisseur data
if(mysql_num_rows($result_5)){
echo '"fournisseur":[';
$first = true;
while($row=mysql_fetch_row($result_5)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode article data
if(mysql_num_rows($result_6)){
echo '"article":[';
$first = true;
while($row=mysql_fetch_row($result_6)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo '],';
} else {
echo '[]';
}
//encode transport data
if(mysql_num_rows($result_7)){
echo '"moyenTransport":[';
$first = true;
while($row=mysql_fetch_row($result_7)){
if($first) {
$first = false;
} else {
echo ',';
}
echo json_encode($row);
}
echo ']}';
} else {
echo '[]';
}
mysql_close($con);
?>
我认为Json格式的问题是因为当我在不同的file.php中分隔对象时它可以工作,但我想使用一个php文件

就像@ jay-blanchard所说的那样,你应该使用像PDO这样的库来运行你的查询,或像Doctrine那样使用完整的ORM。
为了将您的数据显示为Json,您可以使用json_encode为您执行此操作,而不是尝试手动渲染Json。
因此,假设您使用的是Doctrine,您可以这样做:
$camion = $entityManager->createQuery($qry_em_1)->getArrayResult();
$bateau = $entityManager->createQuery($qry_em_2)->getArrayResult();
$transporteur = $entityManager->createQuery($qry_em_3)->getArrayResult();
$trajet = $entityManager->createQuery($qry_em_4)->getArrayResult();
$fournisseur = $entityManager->createQuery($qry_em_5)->getArrayResult();
$article = $entityManager->createQuery($qry_em_6)->getArrayResult();
$mTransport = $entityManager->createQuery($qry_em_7)->getArrayResult();
return json_encode([
'camion' => $camion,
'bateau' => $bateau,
'transporteur' => $transporteur,
'trajet' => $trajet,
'fournisseur' => $fournisseur,
'article' => $article,
'moyenTransport' => $mTransport
]);
