我在这里有以下代码,这是一个post请求与phpMyAdmin交谈的结果。以下JSON文件正在被服务器回显。如何从post请求中快速解析JSON 3
{"account:[{"login":"Nik","id":"0","consent":"0","surveyScore":"0","memoryScore":"0","towerScore":"0","tappingScore":"0"}]}
现在我可以正确地将JSON放到我的手机上,但我无法解析它。
我一直在关注这里列出Xcode Json Example
莅临指导是我到目前为止的代码:
public func sqlAccount(login: String, pass: String, model:userModel) {
// POST REQUEST Only, see php file for web service.
let loci = "http://IPAddressConcealed/"
let appended = loci + "account.php"
var request = URLRequest(url: URL(string: appended)!)
request.httpMethod = "POST"
let postString = "login=\(login)&pass=\(pass)"
request.httpBody = postString.data(using: .utf8)!
let task = URLSession.shared.dataTask(with: request) { data, response, error in
if let reponse = response {
print(reponse)
}
if let data = data {
//print(data)
do{
var accountJson: NSDictionary!
let json = try JSONSerialization.jsonObject(with: data, options: [])
accountJson = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? NSDictionary
print(json)
//getting the json array account from the response
let account: NSArray = accountJson["account"] as! NSArray;
// these two lines I am getting errors on
let login: String = account[0]["login"] as! String
let memoryScore: Int = account[0]["memoryScore"] as! Int
} catch {
print(error)
}
}
}
task.resume()
}`
这是在Xcode终端输出的结果,我只打印JSON数据之后。
`{account = (
{
consent = 0;
id = 0;
login = Nik;
memoryScore = 0;
surveyScore = 0;
tappingScore = 0;
towerScore = 0;
}
); }`
后端PHP代码:
<?php
// Create connection
$con=mysqli_connect("localhost","root","root","sunnytest");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// This SQL statement selects ALL from the table 'Locations'
//$sql = "SELECT * FROM accounts";
// Check if there are results
if ($result = mysqli_query($con, $sql))
{
// If so, then create a results array and a temporary one
// to hold the data
$response = array();
$response['account'] = array();
$tempArray = array();
// Loop through each row in the result set
while($row = $result->fetch_object())
{
// Add each row into our results array
$tempArray = $row;
array_push($response['account'], $tempArray);
}
// Finally, encode the array to JSON and output the results
printf(json_encode($response));
}
// Close connections
mysqli_close($con);
?>
如果您的后端需要JSON,您为什么要将数据编码为.utf8?将其编码为JSON。在解码JSON时,不要使用NSDictionary和NSArray,而要使用本机Swift结构。 –
我的后端不期望JSON,它是一个php文件,用于处理有关测试分数的帐户信息的发布请求。我刚刚按照上面列出的指南。 –
