I have created simple login screen attached with loginViewController.swift. Here are the urls
let login_url = "http://192.168.100.11:9000//users/authenticate"
let checksession_url = "http://192.168.100.11:9000//users/authenticate"
I have simple login api. The web service it is showing response on post man web service but it is not displaying serialized json output on Xcode. How to get serialize json from url?
The api is getting two parameters from username="andrews" and password="admin2"
func login_now(username:String, password:String){
let post_data: NSDictionary = NSMutableDictionary()
post_data.setValue(username, forKey: "username")
post_data.setValue(password, forKey: "password")
let url:URL = URL(string: login_url)!
let session = URLSession.shared
let request = NSMutableURLRequest(url: url)
request.httpMethod = "POST"
request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
var paramString = ""
for (key, value) in post_data {
paramString = paramString + (key as! String) + "=" + (value as! String) + "&"
}
let endIndex = paramString.index(paramString.endIndex, offsetBy: -1)
let truncated = paramString.substring(to: endIndex)
paramString=truncated
print(paramString) // This won't consist of last &
request.httpBody = paramString.data(using: String.Encoding.utf8)
let task = session.dataTask(with: request as URLRequest, completionHandler: {
(
data, response, error) in
guard let _:Data = data, let _:URLResponse = response , error == nil else {
return
}
let json: Any?
do
{
json = try JSONSerialization.jsonObject(with: data!, options: [])
//////////////here json object is not formed to get json output
print("abc")
print(json)
}
catch
{
return
}
guard let server_response = json as? NSDictionary else
{
return
}
if let data_block = server_response["data"] as? NSDictionary
{
if let session_data = data_block["session"] as? String
{
self.login_session = session_data
let preferences = UserDefaults.standard
preferences.set(session_data, forKey: "session")
DispatchQueue.main.async(execute: self.LoginDone)
}
}
})
task.resume()
}
Here json object is not formed to get serialized json output.how to get the serialized json out put on Nslog? You can download the project from this link.

}
There were no problem on server side.But I could not get success response instead What I am getting is {"status":"failure","statusCode":500,"message":"Resource url not found!"}.What mistake am i doing with this code?.Anyone please help me.Thanks in advance.
Try appending '/' at the end of URL.
Eg:
google.com/api/post and google.com/api/post/ are different and trailing slash sometimes gives 500 error, in case of Django-Backend it does.
Here is my code I am getting response and I want to use some values in that
I wrote like this but error is coming
let id = json["emp_id"] as! [String:Any]
let parameters = [
"email": empEm,
"password":"1234"
] as [String : Any]
guard let url = URL(string: "http://localhost:8080/company/employee/login") else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else { return }
request.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: request) { (data, response, error) in
if let response = response {
print(response)
}
if let data = data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: [])
print(json)
let id = json["emp_id"] as! [String:Any]
} catch {
print(error)
}
}
}.resume()
my response is
{
available = 3;
compoff = 0;
displayname = Vamsi;
"emp_id" = 001;
gender = Male;
id = 1;
leaves = 4;
rating = 0;
star = 0;
"termination_date" = active;
wfh = 0;
}
I want to take details like id, emp_id from the response
You need to decode your JSON like this:
let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: Any]
The return value of JSONSerialization.jsonObject is Any, so you need to tell the compiler specifically what kind of object the JSON represents. In your case it is a dictionary, so use [String: Any]

};

}
Error in firebase console:
Actual issue with you is your parameters not getting properly url encoded.
Temporary Solution for your code:
In your convertToParams method, make following changes:
let scapedKeyEncoded = scapedKey.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed);
let scapedValueEncoded = scapedValue.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed);
paramList.append("\(scapedKeyEncoded)=\(scapedValueEncoded)"
Note: Your scapedValue must be String, so, make employeeDetails as [String:String].
Permanent Solution(Perfect way for encoding query parameters):
For this, you can change your code to something like this:
Remove convertToParameters method
Add following method in place of it
class func getURLRequestWith(urlStr:String, paramsDict:[String:String]?, isParamsAsQuery:Bool, isParamsAsBody:Bool) -> URLRequest? {
guard var components = URLComponents(string: urlStr) else { return nil }
if paramsDict != nil{
components.queryItems = paramsDict!.map({ (key, value) -> URLQueryItem in
return URLQueryItem(name: key, value: value)
})
}
if isParamsAsQuery{
let request = URLRequest(url: components.url!);
return request;
}
if isParamsAsBody{
let url = URL(string: urlStr);
var request = URLRequest(url: url!);
let bodyStr = components.percentEncodedQuery;
if bodyStr != nil{
request.httpBody = bodyStr!.data(using: String.Encoding.utf8);
}
return request;
}
let url = URL(string: urlStr);
let request = URLRequest(url: url!);
return request;
}
Remove below lines from your code:
let convertedvalue : String = convertToParameters(employeeDetails)
print("convertedvalues : \(convertedvalue)")
let myUrl = URL(string: "https://us-central1-pickceltest.cloudfunctions.net/rebliss/createNewUser");
var request = URLRequest(url:myUrl!)
request.httpBody = postString.data(using: String.Encoding.utf8);
Add following code instead of above removed code
let urlStr = "https://us-central1-pickceltest.cloudfunctions.net/rebliss/createNewUser"
var request = getURLRequestWith(urlStr: urlStr, paramsDict: employeeDetails, isParamsAsQuery: false, isParamsAsBody: true)
convert employeeDetails dictionary to type [String:String] instead of [String:AnyObject]
Now, try your code and it will surely work.
Please check if below solution works. Add percent encoding to you url.
// Create NSURL Ibject
let url : NSString = urlWithParams as NSString
let urlStr = url.addingPercentEncoding( withAllowedCharacters: .urlQueryAllowed)
let searchURL : NSURL = NSURL(string: urlStr! as String)!
// Creaste URL Request
let request = NSMutableURLRequest(url: searchURL as URL, cachePolicy: NSURLRequest.CachePolicy.reloadIgnoringCacheData, timeoutInterval: 120)
// Set request HTTP method to GET. It could be POST as well
request.httpMethod = "POST"
Have been researching on the parsing for quite a bit. With plethora of information avilable for JSON nothing seems to explain how to do in a sensible way to extract information with swift 3.
This is what got so far
func getBookDetails() {
let scriptUrl = "https://www.googleapis.com/books/v1/volumes?q=isbn:9781451648546" .
let myurl = URL(string:scriptUrl)
let request = NSMutableURLRequest(url: myurl!)
request.httpMethod = "GET"
let task = URLSession.shared.dataTask(with: myurl! ) { (data, response, error) in
if error != nil{
print("THIS ERROR",error!)
return
} else{
if let mydata = data{
do{
let myJson = try (JSONSerialization.jsonObject(with: mydata, options: JSONSerialization.ReadingOptions.mutableContainers)) as AnyObject
// print("this is the MY JSON",myJson) ---> prints out the json
if let dictonary = myJson["items"] as AnyObject? {
print("the DICTONARY",dictonary) // ----> OUTPUT
if let dictonaryAA = dictonary["accessInfo"] as AnyObject? {
print("the accessInfo",dictonaryAA)
}
}
} catch{
print("this is the in CATCH")
}
} //data
}
}
task.resume()
}
}
OUTPUT :
the DICTONARY (
{
accessInfo = {
accessViewStatus = SAMPLE;
country = US;
=============
RELEVANT DATA as in https://www.googleapis.com/books/v1/volumes?
q=isbn:9781451648546"
==========================
title = "Steve Jobs";
};
}
)
Just need to parse through the json data to get the name, author and title of the book with reference to isbn.
Know there should be a better way to do things that is easily understandable to someone new into the language
You can parse the api in two ways
Using URLSession:
let rawDataStr: NSString = "data={\"mobile\":\"9420....6\",\"password\":\"56147180..1\",\"page_no\":\"1\"}"
self.parsePostAPIWithParam(apiName: "get_posts", paramStr: rawDataStr){ ResDictionary in
// let statusVal = ResDictionary["status"] as? String
self.postsDict = (ResDictionary["posts"] as! NSArray!) as! [Any]
print("\n posts count:",self.postsDict.count)
}
func parsePostAPIWithParam(apiName:NSString, paramStr:NSString,callback: #escaping ((NSDictionary) -> ())) {
var convertedJsonDictResponse:NSDictionary!
let dataStr: NSString = paramStr
let postData = NSMutableData(data: dataStr.data(using: String.Encoding.utf8.rawValue)!)
let request = NSMutableURLRequest(url: NSURL(string: "http://13.12..205.248/get_posts/")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = nil
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error as Any)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse as Any)
do{
if let convertedJsonIntoDict = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary {
convertedJsonDictResponse = convertedJsonIntoDict.object(forKey: apiName) as? NSDictionary
// callback for response
callback(convertedJsonDictResponse)
}
} catch let error as NSError {
print(error)
}
}
Using Alamofire
func AlamofirePOSTRequest() {
let urlString = "http://13.12..205.../get_posts/"
let para = ["data": "{\"mobile\":\"9420....6\",\"password\":\"56147180..1\",\"page_no\":\"1\"}"]
Alamofire.request(urlString, method: .post, parameters: para , headers: nil).responseJSON {
response in
switch response.result {
case .success:
print("response: ",response)
let swiftyJsonVar = JSON(response.result.value!)
if let resData = swiftyJsonVar["posts"].arrayObject {
self.postsDict = resData as! [[String:AnyObject]]
}
print("\n \n alomafire swiftyJsonVar: ",swiftyJsonVar)
break
case .failure(let error):
print(error)
}
}
}
})
dataTask.resume()
}
First of all, all JSON types are value types in Swift 3 so the most unspecified type is Any, not AnyObject.
Second of all, there are only two collection types in the JSON type set, dictionary ([String:Any]) and array ([Any], but in most cases [[String:Any]]). It's never just Any nor AnyObject.
Third of all, the given JSON does not contain a key name.
For convenience let's use a type alias for a JSON dictionary:
typealias JSONDictionary = [String:Any]
The root object is a dictionary, in the dictionary there is an array of dictionaries for key items. And pass no options, .mutableContainers is nonsense in Swift.
guard let myJson = try JSONSerialization.jsonObject(with: mydata) as? JSONDictionary,
let items = myJson["items"] as? [JSONDictionary] else { return }
Iterate through the array and extract the values for title and authors which is an array by the way. Both values are in another dictionary for key volumeInfo.
for item in items {
if let volumeInfo = item["volumeInfo"] as? JSONDictionary {
let title = volumeInfo["title"] as? String
let authors = volumeInfo["authors"] as? [String]
print(title ?? "no title", authors ?? "no authors")
The ISBN information is in an array for key industryIdentifiers
if let industryIdentifiers = volumeInfo["industryIdentifiers"] as? [JSONDictionary] {
for identifier in industryIdentifiers {
let type = identifier["type"] as! String
let isbn = identifier["identifier"] as! String
print(type, isbn)
}
}
}
}
You are doing wrong in this line
if let dictonaryAA = dictonary["accessInfo"] as AnyObject?
because dictonary here is an array not dictionary. It is array of dictionaries. So as to get first object from that array first use dictonary[0], then use accessInfo key from this.
I am attaching the code for your do block
do{
let myJson = try (JSONSerialization.jsonObject(with: mydata, options: JSONSerialization.ReadingOptions.mutableContainers)) as AnyObject
// print("this is the MY JSON",myJson) ---> prints out the json
if let array = myJson["items"] as AnyObject? {
print("the array",array) // ----> OUTPUT
let dict = array.object(at: 0) as AnyObject//Master Json
let accessInf = dict.object(forKey: "accessInfo") //Your access info json
print("the accessInfo",accessInf)
}
}
Hope this helps you.
I am getting stuck with HTTP request.it did not show any error.compiler reads the first two lines and skip the code to "task.resume()".i am fetching data with same code on other view controller but it creats problem here
func getCustomers()
{
let url = NSURL(string: "myURL.com")
let task = URLSession.shared.dataTask(with: url! as URL) {
(data, response, error) in
guard let _:Data = data, let _:URLResponse = response , error == nil else {
print("error: \(String(describing: error))")
return
}
do
{
self.getcustomersArray = [GetCustomers]()
//JSON Parsing
if let data = data,
let json = try JSONSerialization.jsonObject(with: data) as? [String: Any]
{
let results = json["Result"] as? [[String : Any]]
let getCustomersObject:GetCustomers = GetCustomers()
for result in results!
{
getCustomersObject.ActivityPrefix = (result["ActivityPrefix"] as? String)!
getCustomersObject.CustomerID = (result["CustomerID"] as? String)!
getCustomersObject.CustomerName = (result["CustomerName"] as? String)!
getCustomersObject.TFMCustomerID = (result["TFMCustomerID"] as? String)!
getCustomersObject.ShortName = (result["ShortName"] as? String)!
getCustomersObject.UserRights = (result["UserRights"] as? Int)!
self.totalCustomers += self.totalCustomers
}
self.customerName = getCustomersObject.CustomerName
}
}//end Do
catch
{
}
}
task.resume()
}
Using Block GET/POST/PUT/DELETE:
let request = NSMutableURLRequest(url: URL(string: "Your API URL here" ,param: param))!,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval:"Your request timeout time in Seconds")
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers as? [String : String]
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest) {data,response,error in
let httpResponse = response as? HTTPURLResponse
if (error != nil) {
print(error)
} else {
print(httpResponse)
}
DispatchQueue.main.async {
//Update your UI here
}
}
dataTask.resume()
I think you dont mention line
request.httpMethod = "GET"
