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="/UploadFiles/2021-04-02/angular.min.js">

运行结果：

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


<"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);
"htmlcode">

<"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);
"htmlcode">

<%@ 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
