AngularJS入门教程中SQL实例详解
AngularJS SQL
在前面章节中的代码也可以用于读取数据库中的数据。
使用 PHP 从 MySQL 中获取数据
AngularJS 实例
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> <style> table, th , td { border: 1px solid grey; border-collapse: collapse; padding: 5px; } table tr:nth-child(odd) { background-color: #f1f1f1; } table tr:nth-child(even) { background-color: #ffffff; } </style> </head> <body> <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) { $http.get("/try/angularjs/data/Customers_MySQL.php") .success(function (response) {$scope.names = response.records;}); }); </script> </body> </html>

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: *");
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
<?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
<%@ 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 As OleDbConnection Dim objAdapter As OleDbDataAdapter Dim objTable As DataTable Dim objRow As DataRow Dim objDataSet As New DataSet() Dim outp Dim c conn = New OledbConnection("Provider=Microsoft.Jet.OLEDB.4.0;data source=Northwind.mdb") objAdapter = New OledbDataAdapter("SELECT CompanyName, City, Country FROM Customers", conn) objAdapter.Fill(objDataSet, "myTable") objTable=objDataSet.Tables("myTable") outp = "" c = chr(34) for each x in objTable.Rows if 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 & "}" next outp ="{" & c & "records" & c & ":[" & outp & "]}" response.write(outp) conn.close %>
4. ASP.NET, VB Razor 和 SQL Lite 代码实例
@{ 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 in query) { 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
以上就是AngularJS SQL资料的整理,后续继续补充,希望能帮助学习的朋友。
