Append data to post body and upload to api - ios

Question

I am calling one api with passing some parameter with including getting some file from icloud like pdf, doc, docx and call the api.
Now i am picking some file from icloud and i need to pass to api call. The issues is my selecting file ( pdf or doc ) is not converting to nsdata and bytes is coming as 0.So its not apending to my body parameters .Help me out where i m doing wrong
My code:
func uploadthefileToserver(){
if let url = URL(string: "https://www.exampleurl/api"){
var request = URLRequest(url: url)
let boundary:String = "Boundary-\(UUID().uuidString)"
// let request = NSMutableURLRequest(url:myUrl! as URL);
request.httpMethod = "POST"
request.timeoutInterval = 10
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let postJobData:[String:Any] = ["UserId":"107","name":"hardcodevalue"]
var dataFile: Data = Data()
print(fullDestPath) ///Users/sathish/Library/Developer/CoreSimulator/Devices/4464E7A8-0F38-4802-B645-19721D251054/data/Containers/Data/Application/714B1B8E-5872-42B9-B963-B0C51C9403D7/Documents/NewFileiCloud/iOS.DOCX"
do{
dataFile = try NSData.init(contentsOf: URL(fileURLWithPath: fullDestPath, isDirectory: true)) as Data
print(dataFile)
}catch{
print(error)
}
if(dataFile==nil) { return; }
print(dataFile) //0 bytes
request.httpBody = createBodyWithParameters(parameters: postJobData, filePathKey: "Resume", FileData: dataFile as NSData , boundary: boundary) as Data
print(postJobData)
print(dataFile)
let task = URLSession.shared.dataTask(with: request as URLRequest) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}else if let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue){
print("****** response data = \(responseString)")
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary
print(json)
let status = json!["Success"] as! String
let errMessage = json!["Message"] as? String
DispatchQueue.main.async() {
if status == "1"{
print(errMessage)
}else{
print(errMessage)
}
}
}catch{
print(error)
}
}
}; task.resume()
}
}
Not sure where i am doing wrong. I put some print functions for the referance.
Main parts :
dataFile = try NSData.init(contentsOf: URL(fileURLWithPath:
fullDestPath, isDirectory: true)) as Data
request.httpBody = createBodyWithParameters(parameters: postJobData,
filePathKey: "Resume", FileData: dataFile as NSData , boundary:
boundary) as Data
Thanks
Update :
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
print("url = \(urls)")
filePathUrl = urls
print(filePathUrl)
for urll in filePathUrl{
filepath = filePathUrl[0] as! URL
print(filepath)
filePathString = filepath.path
urlstr = NSURL(fileURLWithPath: filePathString).lastPathComponent!
print(urlstr)
// Data object to fetch weather data
do {
let weatherData = try NSData(contentsOf: filepath, options: NSData.ReadingOptions())
print(weatherData)
} catch {
print(error)
}
}
let destPath:NSArray = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) as NSArray
let fileManager = FileManager.default
print(destPath, "\n")
documentDir = destPath[0] as? NSString
let filePath = documentDir?.appendingPathComponent("NewFileiCloud") as! NSString
// if fileManager.fileExists(atPath: filePath as String){
do {
// try fileManager.createDirectory(atPath: filePath as String, withIntermediateDirectories: false, attributes: nil)
fullDestPath = filePath.appendingPathComponent(urlstr)

You are trying to do,
Convert PDFURL to Data
Convert Data to .PDF
Storing that .PDF in Doc.Dir.
Retriving that .PDF from Doc.Dir and Pass to Server.
For the above task, you have to create folder NewFileiCloud in Doc.Dir. Then, convert pdfUrl to data and write that data to .pdf file, and then, get that .pdf path from doc.dir and convert that into Data and pass to server.
I have did sample for you. This will satisfy you.
override func viewDidAppear(_ animated: Bool) {
// I have did sample for you by taking .pdf from bundle.
if let pathPDF = Bundle.main.path(forResource: "sample", ofType: "pdf") {
let path = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentDirectoryPath:String = path[0]
let fileManager = FileManager()
var destinationURLForFile = URL(fileURLWithPath: documentDirectoryPath.appending("/NewFileiCloud"))
do {
//You have to create directory with above name.
try fileManager.createDirectory(at: destinationURLForFile, withIntermediateDirectories: true, attributes: nil)
destinationURLForFile.appendPathComponent("reader.pdf")
//YOUR PDF URL [pathPDF [my bundle path, you have to give your URL]] to DATA
let pdfData = try Data(contentsOf: URL(fileURLWithPath: pathPDF))
// WRITE ITS CONTENT to Doc.Dir.
try pdfData.write(to: destinationURLForFile, options:.atomic)
//ASSIGN PATH TO GLOBAL URL VARIABLE
fullPAth = destinationURLForFile
print("conclude ", destinationURLForFile)
uploadToServer()
}
catch(let error){
print(error)
}
}
}
func uploadToServer() {
.....
do {
// Here you can get PDF contents as Data.
// With this Data, you can pass to Server Side.
let pdfPOSTData = try Data(contentsOf: fullPAth!)
}
catch let e{
print("Catch_Not_worlk ", e)
}
......
}
