How can I obtain POST request body from WKWebView in Swift?

How can I obtain POST request body from WKWebView in Swift?

it fixes the issue I'm answering my own question because I figured out how to do this on my own. Perhaps my question wasn't clear. My end goal was to extract the body content as a string.
Firstly, I ditched the callback I used:
code :
func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
    // do stuff
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    webView.evaluateJavaScript("document.getElementById(\"my-id\").innerHTML", completionHandler: { (jsonRaw: Any?, error: Error?) in
        guard let jsonString = jsonRaw as? String else { return }
        let json = JSON(parseJSON: jsonString)
        // do stuff

this will help You're close. The parameters dictionary formatting doesn't look correct. You should try the following:
code :
let parameters: [String: AnyObject] = [
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List": [
            "IdQuestion" : 5,
            "IdProposition": 2,
            "Time" : 32
            "IdQuestion" : 4,
            "IdProposition": 3,
            "Time" : 9

    .responseJSON { request, response, JSON, error in

With these it helps I want to make a POST request from iOS (swift3) which passes a chunk of raw bytes as the body. I had done some experimenting which made me thought the following worked: , The two common solutions are:
code :
let base64Encoded = data
    .base64EncodedString(options: [])
    .addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)!
    .data(using: String.Encoding.utf8)!

var body = "key=".data(using: .utf8)!

var request = URLRequest(url: url)
request.httpBody = body
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard error == nil else {

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

hope this fix your issue You can directly generate a code from postman itself. Also, for your reference, you can call post request with row body as given below.
code :
let headers = [
        "content-type": "application/json",
        "cache-control": "no-cache"

    let parameters = ["order": ["line_items": [
                                            ["variant_id": 18055889387589,
                                             "quantity": 1]
                     ]]] as [String : Any]

    let postData = try? JSONSerialization.data(withJSONObject: parameters, options: [])

    if let data = postData {
        let request = NSMutableURLRequest(url: NSURL(string: "http://")! as URL,
                                          cachePolicy: .useProtocolCachePolicy,
                                          timeoutInterval: 10.0)
        request.httpMethod = "POST"
        request.allHTTPHeaderFields = headers
        request.httpBody = data 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?.localizedDescription ?? "")
            } else {
                let httpResponse = response as? HTTPURLResponse
                print(httpResponse?.statusCode ?? 0)

                let reponseData = String(data: data!, encoding: String.Encoding.utf8)
                print("responseData: \(reponseData ?? "Blank Data")")

wish of those help I think I went somewhere wrong copying/pasting code from stack overflow without understanding. , Please Try this code :
code :
    // prepare json data
    let json: [String: Any] = ["testConfigKey": "testing"]

    let parameters = try? JSONSerialization.data(withJSONObject: json)

    // create post request
    let url = URL(string: checkUserConfig)!
    var apiRequest = URLRequest(url: url)
    apiRequest.httpMethod = "POST"
    apiRequest.addValue("application/json",forHTTPHeaderField: "Content-Type")

    // insert json data to the request
    apiRequest.httpBody = parameters

    let task = URLSession.shared.dataTask(with: apiRequest) { data, response, error in
        guard let data = data, error == nil else {
            print(error?.localizedDescription ?? "No data Available")
        let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
        if let responseJSON = responseJSON as? [String: Any] {

To fix this issue So, as I understood correctly you're using Google Maps API and the request you're trying to perform is a GET request which means that you need to specify request parameters in the URL itself, not the body. I think your request should look like this
code :
    let googleKey = "your api key"
    let url: String = "maps.googleapis.com/maps/api/place/autocomplete/json?input=Apple&components=country:ids&input=\(str)&types=adress&key=\(googleKey)"
    Alamofire.request(url, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: nil).responseJSON
