AngularJS SQL
在前面章節(jié)中的代碼也可以用于讀取數(shù)據(jù)庫中的數(shù)據(jù)。
使用 PHP 從 MySQL 中獲取數(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 請求。
跨域請求在網(wǎng)頁上非常常見。很多網(wǎng)頁從不同服務(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，所有請求被嚴(yán)格限制在同一域名下，如果需要調(diào)用不同站點的數(shù)據(jù)，需要通過跨域來解決。
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 代碼實例
<?phpheader("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($outp);?>2. PHP 和 MS Access 代碼實例
<?phpheader("Access-Control-Allow-Origin: *");header("Content-Type: application/json; charset=ISO-8859-1");$conn = new COM("ADODB.Connection");$conn->open("PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=Northwind.mdb");$rs = $conn->execute("SELECT CompanyName, City, Country FROM Customers");$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 OleDbConnectionDim objAdapter As OleDbDataAdapterDim objTable As DataTableDim objRow As DataRowDim objDataSet As New DataSet()Dim outpDim cconn = 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.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 代碼實例
@{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。
