AngularJS SQL

使用 PHP 从 MySQL 中获取数据

示例代码 
<divng-app="myApp"ng-controller="customersCtrl"><table><trng-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("https://www.ez4code.com/try/angularjs/data/Customers_MySQL.php").success(function (response) {$scope.names = response.records;});});</script>

ASP.NET 中执行 SQL 获取数据

示例代码 
<divng-app="myApp"ng-controller="customersCtrl"><table><trng-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("https://www.ez4code.com/try/angularjs/data/Customers_SQL.aspx").success(function (response) {$scope.names = response.records;});});</script>

服务端代码

以下列出了几种服务端代码类型：

  1. 使用 PHP 和 MySQL。返回 JSON。
  2. 使用 PHP 和 MS Access。返回 JSON。
  3. 使用 ASP.NET, VB, 及 MS Access。 返回 JSON。
  4. 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。

示例代码 
header("Access-Control-Allow-Origin: *");

更多跨域访问解决方案可参阅： PHP Ajax 跨域问题最佳解决方案 。

1. PHP 和 MySql 代码实例

示例代码 
<?phpheader("Access-Control-Allow-Origin: *");header("Content-Type:application/json; charset=UTF-8");$conn =new mysqli("myServer", "myUser", "myPassword", "Northwind");$result = $conn->query("SELECTCompanyName, City, Country FROM Customers");$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

示例代码 
<?phpheader("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 = $conn->execute("SELECT CompanyName, City, Country FROMCustomers");$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

示例代码 
<%@ Import Namespace="System.IO"%><%@ Import Namespace="System.Data"%><%@ Import Namespace="System.Data.OleDb"%><%Response.AppendHeader("Access-Control-Allow-Origin", "*")Response.AppendHeader("Content-type", "application/json")Dim conn AsOleDbConnectionDim objAdapter As OleDbDataAdapterDim objTable AsDataTableDim objRow As DataRowDim objDataSet As New DataSet()Dim outpDim cconn = New OledbConnection("Provider=Microsoft.Jet.OLEDB.4.0;datasource=Northwind.mdb")objAdapter = New OledbDataAdapter("SELECTCompanyName, City, Country FROM Customers", conn)objAdapter.Fill(objDataSet,"myTable")objTable=objDataSet.Tables("myTable")outp = ""c = chr(34)for each x in objTable.Rowsif outp <> "" then outp = outp & ","outp = outp & "{" & c & "Name"    & c & ":" & c & x("CompanyName")& c & ","outp = outp &       c & "City"    & c & ":" & c& x("City")        & c & ","outp = outp &       c & "Country" & c& ":" & c & x("Country")     & c & "}"nextoutp="{" & c & "records" & c & ":[" & outp & "]}"response.write(outp)conn.close%>

4. ASP.NET, VB Razor 和 SQL Lite 代码实例

示例代码 
@{Response.AppendHeader("Access-Control-Allow-Origin", "*")Response.AppendHeader("Content-type", "application/json")var db =Database.Open("Northwind");var query = db.Query("SELECT CompanyName,City, Country FROM Customers");var outp =""var c = chr(34)}@foreach(var row inquery){if outp <> "" then outp = outp + ","outp = outp + "{" + c + "Name"    + c + ":" + c+ @row.CompanyName + c + ","outp = outp +       c+ "City"    + c + ":" + c+ @row.City        + c + ","outp = outp+       c + "Country" + c+ ":" + c + @row.Country     + c + "}"}outp ="{" + c+ "records" + c + ":[" + outp + "]}"@outp
