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：
Alfreds Futterkiste Germany Ana Trujillo Emparedados y helados Mexico Antonio Moreno Taquería Mexico Around the Horn UK B's Beverages UK Berglunds snabbköp Sweden Blauer See Delikatessen Germany Blondel père et fils France Bólido Comidas preparadas Spain Bon app' France Bottom-Dollar Marketse Canada Cactus Comidas para llevar Argentina Centro comercial Moctezuma Mexico Chop-suey Chinese Switzerland Comércio Mineiro Brazil
ASP.NET 中执行 SQL 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：
Alfreds Futterkiste Germany Berglunds snabbköp Sweden Centro comercial Moctezuma Mexico Ernst Handel Austria FISSA Fabrica Inter. Salchichas S.A. Spain Galería del gastrónomo Spain Island Trading UK Königlich Essen Germany Laughing Bacchus Wine Cellars Canada Magazzini Alimentari Riuniti Italy North/South UK Paris spécialités France Rattlesnake Canyon Grocery USA Simons bistro Denmark The Big Cheese USA Vaffeljernet Denmark Wolski Zajazd Poland
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。
