AngularJS SQL
使用 php 从 mysql 中获取数据
<div ng-app="myApp" ng-controller="customersCtrl">
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name}}</td>
<td>{{ x.Country}}</td>
</tr>
</table>
</div>
<script>
var app = angular.module(‘myApp‘,[]);
app.controller(‘customersCtrl‘,function($scope, $http){
$http.get("test.php")
.success(function(response){$scope.names = response.records;});
});
</script>
ASP.NET 中执行 SQL 获取数据
<div ng-app="myApp" ng-controller="customersCtrl">
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name}}</td>
<td>{{ x.Country}}</td>
</tr>
</table>
</div>
<script>
var app = angular.module(‘myApp‘,[]);
app.controller(‘customersCtrl‘,function($scope, $http){
$http.get("test.aspx")
.success(function(response){$scope.names = response.records;});
});
</script>
test.aspx 内容:
{"records":[
{

服务端代码
以下列出了列出了几种服务端代码类型:
- 使用 PHP 和 MySQL。返回 JSON。
- 使用 PHP 和 MS Access。返回 JSON。
- 使用 ASP.NET, VB, 及 MS Access。 返回 JSON。
- 使用 ASP.NET, Razor, 及 SQL Lite。 返回 JSON。
跨域 HTTP 请求
如果你需要从不同的服务器(不同域名)上获取数据就需要使用跨域 HTTP 请求。
跨域请求在网页上非常常见。很多网页从不同服务器上载入 CSS, 图片,Js脚本等。
在现代浏览器中,为了数据的安全,所有请求被严格限制在同一域名下,如果需要调用不同站点的数据,需要通过跨域来解决。
以下的 PHP 代码运行使用的网站进行跨域访问。
header("Access-Control-Allow-Origin: *");
1. PHP 和 MySql 代码实例
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
$conn =new mysqli("myServer","myUser","myPassword","Northwind");
$result = $conn->query("SELECT CompanyName, City, Country FROM Customers");
$outp ="";
while($rs = $result->fetch_array(MYSQLI_ASSOC)){
if($outp !=""){$outp .=",";}
$outp .=‘{"Name":"‘. $rs["CompanyName"].‘",‘;
$outp .=‘"City":"‘. $rs["City"].‘",‘;
$outp .=‘"Country":"‘. $rs["Country"].‘"}‘;
}
$outp =‘{"records":[‘.$outp.‘]}‘;
$conn->close();
echo($outp);
?>
2. PHP 和 MS Access 代码实例
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=ISO-8859-1");
$conn =new COM("ADODB.Connection");
$conn->open("PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=Northwind.mdb");
$rs = $conn->execute("SELECT CompanyName, City, Country FROM Customers");
$outp ="";
while(!$rs->EOF){
if($outp !=""){$outp .=",";}
$outp .=‘{"Name":"‘. $rs["CompanyName"].‘",‘;
$outp .=‘"City":"‘. $rs["City"].‘",‘;
$outp .=‘"Country":"‘. $rs["Country"].‘"}‘;
$rs->MoveNext();
}
$outp =‘{"records":[‘.$outp.‘]}‘;
$conn->close();
echo ($outp);
?>
3. ASP.NET, VB 和 MS Access 代码实例
