AngularJS入門教程中SQL實(shí)例詳解

 更新時(shí)間：2016年07月27日 17:54:46   投稿：lqh  
本文主要介紹 AngularJS SQL,這里給大家整理了相關(guān)資料，并提供了實(shí)例代碼,有需要的小伙伴可以參考下

AngularJS SQL

在前面章節(jié)中的代碼也可以用于讀取數(shù)據(jù)庫(kù)中的數(shù)據(jù)。

使用 PHP 從 MySQL 中獲取數(shù)據(jù)

AngularJS 實(shí)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>

ASP.NET 中執(zhí)行 SQL 獲取數(shù)據(jù)

服務(wù)端代碼

以下列出了列出了幾種服務(wù)端代碼類型：

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 請(qǐng)求

如果你需要從不同的服務(wù)器（不同域名）上獲取數(shù)據(jù)就需要使用跨域 HTTP 請(qǐng)求。
跨域請(qǐng)求在網(wǎng)頁(yè)上非常常見。很多網(wǎng)頁(yè)從不同服務(wù)器上載入 CSS, 圖片，Js腳本等。
在現(xiàn)代瀏覽器中，為了數(shù)據(jù)的安全，所有請(qǐng)求被嚴(yán)格限制在同一域名下，如果需要調(diào)用不同站點(diǎn)的數(shù)據(jù)，需要通過跨域來(lái)解決。
以下的 PHP 代碼運(yùn)行使用的網(wǎng)站進(jìn)行跨域訪問。

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

更多跨域訪問解決方案可參閱：PHP Ajax 跨域問題最佳解決方案。

1. PHP 和 MySql 代碼實(shí)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 代碼實(shí)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 代碼實(shí)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 代碼實(shí)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資料的整理，后續(xù)繼續(xù)補(bǔ)充,希望能幫助學(xué)習(xí)的朋友。
