我目前拥有以下带有选择查询的PHP脚本,其中包含所有硬编码值。如何获取我的Swift应用提供的价值?
有没有一种方法可以轻松地编辑以下代码,我还必须具有一个POST值,而不是在PHP脚本中具有一个硬编码的值?
// Create connection
$con=mysqli_connect("localhost”,”username”,”password”,”dbName”);
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// This SQL statement selects ALL from the table 'Equipment'
$sql = "SELECT name FROM TABLE
WHERE name = ‘$CHANGE THIS’ ";
// Check if there are results
if ($result = mysqli_query($con, $sql))
{
// Create temporary connection
$resultArray = array();
$tempArray = array();
// Look through each row
while($row = $result->fetch_object())
{
// Add each row into our results array
$tempArray = $row;
array_push($resultArray, $tempArray);
}
// Finally, encode the array to JSON and output the results
echo json_encode($resultArray);
}
mysqli_close($con);
我当前在Swift中的代码如下:
然后将我从SQL查询中获取的数据放入数组中,并在UITable中设置格式:
import Foundation
protocol FeedDetailProtocol: class {
func itemsDownloaded(items: NSArray)
}
class FeedDetail: NSObject, URLSessionDataDelegate {
weak var delegate: FeedDetailProtocol!
let urlPath = "https://www.example.com/test/test1.php"
func downloadItems() {
let url: URL = URL(string: urlPath)!
let defaultSession = Foundation.URLSession(configuration: URLSessionConfiguration.default)
let task = defaultSession.dataTask(with: url) { (data, response, error) in
if error != nil {
print("Error")
}else {
print("details downloaded")
self.parseJSON(data!)
}
}
task.resume()
}
func parseJSON(_ data:Data) {
var jsonResult = NSArray()
do{
jsonResult = try JSONSerialization.jsonObject(with: data, options:JSONSerialization.ReadingOptions.allowFragments) as! NSArray
} catch let error as NSError {
print(error)
}
var jsonElement = NSDictionary()
let stocks = NSMutableArray()
for i in 0 ..< jsonResult.count
{
jsonElement = jsonResult[i] as! NSDictionary
let stock = DetailModel()
//the following insures none of the JsonElement values are nil through optional binding
if let name = jsonElement["name"] as? String,
{
print(name)
stock.name = name
}
stocks.add(stock)
}
DispatchQueue.main.async(execute: { () -> Void in
self.delegate.itemsDownloaded(items: stocks)
})
}
}
