Not sure what the issues is as my code just stopped working overnight, but the text detection on Google Vision is either returning nil or returning words that are non-existent on the subject.
Here's my request function:
func createRequest(with imageBase64: String) {
let jsonRequest = [
"requests": [
"image": [
"content": imageBase64 ],
"features": [
["type": "TEXT_DETECTION"],
["type": "IMAGE_PROPERTIES"]
]
]
]
let jsonData = try? JSONSerialization.data(withJSONObject: jsonRequest)
var request = URLRequest(url: googleURL)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue(Bundle.main.bundleIdentifier ?? "", forHTTPHeaderField: "X-Ios-Bundle-Identifier")
request.httpBody = jsonData
DispatchQueue.global().async {
let task: URLSessionDataTask = self.URLsession.dataTask(with: request) { (encodedObject, response, error) in
guard let data = encodedObject, error == nil else {
print(error?.localizedDescription ?? "no data")
return
}
self.analyzeResults(data)
}
task.resume()
}
}
Part of my analyze results function:
func analyzeResults(_ data: Data) {
DispatchQueue.main.async {
guard let response = try? JSONDecoder().decode(Root.self, from: data) else { return }
guard let responseArray = response.responses else { return }
print(response)

I'm trying to pass an array of parameters that looks like this:
{
"watermarks": [
{
"email" : "correo_user",
"event_type" : "app",
"watermark" : "marcaAgua",
"date" : "date",
"location" : "location",
"segment" : 1,
"time" : "time",
"country" : "country",
"city" : "city"
}
]
}
I don't know how to pass it as an array of objects because I have never done it before. This is the code that I'm currently using:
func marcaAgua(parameters: [String: Any],
completion: #escaping (Result<[MarcaAguaResData], Error>)-> Void) {
let urlString = baseUrl + "events"
guard let url = URL(string: urlString) else {
completion(.failure(NetworkingError.badUrl))
return
}
var request = URLRequest(url: url)
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters)
request.httpMethod = "POST"
request.setValue("Bearer \(token_login)", forHTTPHeaderField: "Authorization")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
DispatchQueue.main.async {
guard let unwrappedResponse = response as? HTTPURLResponse else {
completion(.failure(NetworkingError.badResponse))
return
}
switch unwrappedResponse.statusCode {
case 200 ..< 300:
print("success")
default:
print("failure")
}
if let unwrappedError = error {
completion(.failure(unwrappedError))
return
}
if let unwrappedData = data {
print("QQQQQ")
print(unwrappedData)
do{
let json = try JSONSerialization.jsonObject(with: unwrappedData, options:.allowFragments)
if let successRes = try? JSONDecoder().decode([MarcaAguaResData].self, from: unwrappedData){
completion(.success(successRes))
}else{
let errorResponse = try JSONDecoder().decode([MarcaAguaErrorResponse].self, from: unwrappedData)
print("Error \(errorResponse)")
completion(.failure(errorResponse as! Error))
}
}catch{
print("AAA")
completion(.failure(error))
}
}
}
}
task.resume()
}
When I pass the parameters to the function when I call it, I pass them as a dictionary of type [String:Any]. This is an example of it:
let signupQueryData : [String : Any] = [
"watermarks": [
"email" : correo_user as String,
"event_type" : "app" as String,
"watermark" : marcaAgua as String,
"date" : "\(dateActual) \(hour):\(minutes)" as String,
"location" : latitudYLongitud as String,
"segment" : 1 as Int,
"time" : "\(hour):\(minutes)" as String,
"country" : "\(qlq)" as String,
"city" : "Caracas" as String
]
]
And this is what it prints of parameters in the function marcaAgua:
["watermarks": ["time": "22:10", "segment": 1, "location": "location", "email": "mail", "event_type": "app", "watermark": "e356eaadcb3aa4a1049441fc48d83a22", "date": "13.07.2021 22:10", "country": "Venezuela", "city": "Caracas"]]
When I do that, I get the following error:
failure(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.})
Try do like this
func marcaAgua(parameters: [String: Any],
completion: #escaping (Result<[MarcaAguaResData], Error>)-> Void) {
let urlString = baseUrl + "events"
guard let url = URL(string: urlString) else {
completion(.failure(NetworkingError.badUrl))
return
}
var request = URLRequest(url: url)
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters)
request.httpMethod = "POST"
request.setValue("Bearer \(token_login)", forHTTPHeaderField: "Authorization")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
DispatchQueue.main.async {
guard let unwrappedResponse = response as? HTTPURLResponse else {
completion(.failure(NetworkingError.badResponse))
return
}
switch unwrappedResponse.statusCode {
case 200 ..< 300:
print("success")
default:
print("failure")
}
if let unwrappedError = error {
completion(.failure(unwrappedError))
return
}
if let unwrappedData = data {
do{
let json = try JSONSerialization.jsonObject(with: unwrappedData, options:.allowFragments)
if let successRes = try? JSONDecoder().decode([MarcaAguaResData].self, from: unwrappedData){
completion(.success(successRes))
}else{
let errorResponse = try JSONDecoder().decode([MarcaAguaErrorResponse].self, from: unwrappedData)
completion(.failure(errorResponse as! Error))
}
}catch{
completion(.failure(error))
}
}
}
}
task.resume()
}

This is API http://itaag-env-1.ap-south-1.elasticbeanstalk.com/filter/taggedusers/
its parameter: "contactsList" : ["5987606147", "6179987671", "5082508888"]
its header: ["deviceid": "584D97F-761A-4C24-8C4B-C145A8B8BD75", "userType": "personal", "key": "9609cc826b0d472faf9967370c095c21"]
In my code if i put breakpoint then filtertaggedUser() is calling but i am unable to go inside completionHandler the access is not going inside dataTask
Access going to else part why? the api is working.
i am trying to pass parameter key value in URL string like below
let urlStr = "http://itaag-env-1.ap-south-1.elasticbeanstalk.com/filter/taggedusers/?contactsList=" + "8908908900"
is this correct approch?
code for above API:
func filtertaggedUser() {
print("inside filter taggedusers")
let headers = ["deviceid": "584D97F-761A-4C24-8C4B-C145A8B8BD75", "userType": "personal", "key": "9609cc826b0d472faf9967370c095c21"]
let urlStr = "http://itaag-env-1.ap-south-1.elasticbeanstalk.com/filter/taggedusers/?contactsList=" + "8908908900"
let request = NSMutableURLRequest(url: NSURL(string:urlStr)! as URL,cachePolicy: .useProtocolCachePolicy,timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
// access not coming here
let httpResponse = response as? HTTPURLResponse
if httpResponse!.statusCode == 200 {
print("filter taggedusers inside")
do {
print("filter taggedusers inside do")
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String :AnyObject]
print("filter taggedusers \(jsonObject)")
} catch { print(error.localizedDescription) }
} else { Constants.showAlertView(alertViewTitle: "", Message: "Something went wrong, Please try again", on: self) }
})
dataTask.resume()
}
OUTPUT:
POSTMAN OUTPUT
POSTMAN Body
why response is not coming, where i did mistake, please help me with the code.
We can call the Post request API like below,
func getPostString(params:[String:Any]) -> String
{
var data = [String]()
for(key, value) in params
{
data.append(key + "=\(value)")
}
print(data.map { String($0) }.joined(separator: "&"))
return data.map { String($0) }.joined(separator: "&")
}
func callPostApi(){
let url = URL(string: "http://itaag-env-1.ap-south-1.elasticbeanstalk.com/filter/taggedusers/")
guard let requestUrl = url else { fatalError() }
var request = URLRequest(url: requestUrl)
request.httpMethod = "POST"
request.setValue("584D97F-761A-4C24-8C4B-C145A8B8BD75", forHTTPHeaderField: "deviceid")
request.setValue("9609cc826b0d472faf9967370c095c21", forHTTPHeaderField: "key")
request.setValue("personal", forHTTPHeaderField: "userType")
let parameters = getPostString(params: ["contactsList":["8908908900"]])
request.httpBody = parameters.data(using: .utf8)
// Perform HTTP Request
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
let httpResponse = response as? HTTPURLResponse
print(httpResponse!.statusCode)
// Check for Error
if let error = error {
print("Error took place \(error)")
return
}
// Convert HTTP Response Data to a String
if let data = data, let dataString = String(data: data, encoding: .utf8) {
print("Response data string:\n \(dataString)")
}
}
task.resume()
}
Output :

This is how I am making an api request using URLSession:
let url = URL(string: "http://192.168.1.21.2/FeatureRequestComponent/FeatureRequestComponentAPI")!
var request = URLRequest(url: url)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
let parameters: [String: Any] = [
"AppID": "67B10F42-A372-4D4B-B630-5933E3F7FD65",
"FeatureTitle": "ABCD",
"UserName": "Ayaz",
"UserEmail": self.userEmailTextfield.text ?? "",
"Priority":"H",
"Description": self.featureDescriptionTextView.text ?? "",
"UseCase": self.useCaseTextView.text ?? "",
"DeviceType" : "iPhone"
]
request.httpBody = parameters.percentEscaped().data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data,
let response = response as? HTTPURLResponse,
error == nil else { // check for fundamental networking error
print("error", error ?? "Unknown error")
return
}
guard (200 ... 299) ~= response.statusCode else { // check for http errors
print("statusCode should be 2xx, but is \(response.statusCode)")
print("response = \(response)")
return
}
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(responseString)")
}
task.resume()
}
extension Dictionary {
func percentEscaped() -> String {
return map { (key, value) in
let escapedKey = "\(key)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
let escapedValue = "\(value)".addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed) ?? ""
return escapedKey + "=" + escapedValue
}
.joined(separator: "&")
}
}
extension CharacterSet {
static let urlQueryValueAllowed: CharacterSet = {
let generalDelimitersToEncode = ":#[]#" // does not include "?" or "/" due to RFC 3986 - Section 3.4
let subDelimitersToEncode = "!$&'()*+,;="
var allowed = CharacterSet.urlQueryAllowed
allowed.remove(charactersIn: "\(generalDelimitersToEncode)\(subDelimitersToEncode)")
return allowed
}()
}
above I have given the extensions for percent escaped and a character set also
But the response I get is an error like this:
responseString = Optional("{\"isError\":true,\"ErrorMessage\":\"Unknown Error Occured\",\"Result\":{},\"ErrorCode\":999}")
What am I doing wrong here...? I'm supposed to get a success in my response but what I'm getting is the error message.
I tried to detect the problem in your code but I did not find it
use my code war it works well
I hope this helps you
let jsonData = try? JSONSerialization.data(withJSONObject: ["username":username,"password":password])
var request = URLRequest(url: URL(string: "http://api.com/login")!)
request.httpMethod = "POST";
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "No data")
return
}
let dataJSON = try? JSONSerialization.jsonObject(with: data, options: [])

I'm am trying to use the data of this request. I don't know how to receive data that comes in NSArray. So what I want to know is how can I use each one of the values that are in the array like "addresses" and "awards"?
(I'm using Swifty framework)
This is the server response and the data what I want to use. or better store it in a variable.
[
{
"addresses": [
{
"idAddress": 1,
"idProgram": 1,
"descriptionAddress": "Address1",
"registerDateAddress": "2017-09-12T11:03:53.083",
"isActive": true
}
],
"awards": [
{
"idAward": 1,
"idProgram": 1,
"nameAward": "Awards1",
"descriptionAward": "ImagenAward1",
"imageAward": "ImagenAward1.png",
"registerDateAward": "2017-09-12T11:03:57.67",
"isActive": true
}
]
And this is my code:
func getTheProgram(onSuccess: #escaping(JSON) -> Void, onFailure: #escaping(Error) -> Void) {
print("xxxxxxxxxx", userId ?? "")
guard let url = URL(string: "http://www.my_url.com") else {return}
var request = URLRequest(url: url)
request.httpMethod = "GET"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("xxxxxxxxx", forHTTPHeaderField: "Authorization")
let session = URLSession.shared
let task = session.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in
if let response = response {
print("Response",response)
}
if let data = data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as! NSArray
print(json )
let result = JSON(data: data)
onSuccess(result)
print("xxxxxx")
} catch {
print(error)
print("xxxxxxx")
}
}
if(error != nil){
onFailure(error!)
print("xxxxxx")
} else{
}
})
task.resume()
}
I am starting my adventure with Swift and iOS developing. And I am fighting for few hours with parsing this json result:
[
[
{
"id": 289462,
"value": "24.80",
"taken_at": "2017-07-02 19:03:03",
"key": "temperature"
}
],
[
{
"id": 289463,
"value": "52.20",
"taken_at": "2017-07-02 19:03:05",
"key": "humidity"
}
]
]
It hasn't got this "name" before all of results, and I don't know, maybe this is causing errors? And below is my function to get data:
func get_data()
{
let headers = [
"content-type": "application/x-www-form-urlencoded",
"cache-control": "no-cache",
"postman-token": "fd20c3c4-650e-743c-3066-597de91f3873"
]
let postData = NSMutableData(data: "auth_key=32fd26f62677e7aa56027d9c228e1e9d6d96abc5d10f547dcb66e2a2f6ed13".data(using: String.Encoding.utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "http://192.168.0.22/last")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
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)
} else {
//let httpResponse = response as? HTTPURLResponse
var keys = [String]()
do {
if let data = data,
let json = try JSONSerialization.jsonObject(with: data) as? [String: Any],
let mes = json[""] as? [[String: Any]] {
for me in mes {
if let name = me["key"] as? String {
keys.append(name)
}
}
}
} catch {
print("Error deserializing JSON: \(error)")
}
print(keys)
}
})
dataTask.resume()
}
I've tried several codes from different sites which I googled and still array is remaining empty :(
You're right the JSON is strange, the root object is [[Any]]. You can get the key values with
if let json = try JSONSerialization.jsonObject(with: data) as? [[Any]] {
for item in json {
if let firstItem = item.first as? [String:Any], let key = firstItem["key"] as? String {
keys.append(key)
}
}
}
However if the JSON was in much more suitable format
[
{
"id": 289462,
"value": "24.80",
"taken_at": "2017-07-02 19:03:03",
"key": "temperature"
},
{
"id": 289463,
"value": "52.20",
"taken_at": "2017-07-02 19:03:05",
"key": "humidity"
}
]
you could reduce the code to
if let json = try JSONSerialization.jsonObject(with: data) as? [[String:Any]] {
keys = json.flatMap { $0["key"] as? String }
}
