CookieManager

[MattHamburger]

In my app I am logging in to a server using HttpClient in http.dart. I get two cookies from the server and use them in all requests.
I need to use embedded web views in several places so I am trying to use the inappbrowser.

Is there a way to set the cookies?

[pichillilorenzo]

Did you try the CookieManager class already?

[MattHamburger]

I did but I am not sure how to use it, I have a loop where I get the cookie key/values and within the loop I have:
CookieManager.setCookie(
"https://ev01-data1.mycompany.com:446", cookie.name, cookie.value,
domain: ".mycompany.com",
isSecure: true,
path: "/",
)
This is called two times with a different key/value.

Any update on this? I'm also getting this issue...

[VincentTung1]

Hello,I have ever occurred this problem for a long time , util now, I could not find any solution.
I have ever tried to put the cookie name and value to the header, just could verify in home page.
But,if its child page needs to take the cookie for sub verify, it failed.
I take this question is to find the solution for IOS Device,it seems to cannot read the cookies successfully.I really want to find some solutions from yours.Thanks!

@MattHamburger Try the latest version of the plugin. Also, this plugin changed its name to flutter_inappwebview. The current latest version now is 2.1.0+1. So, you can change your dependency influtter_inappwebview: ^2.1.0+1.

A full example where I set custom cookies that I tried on both Android (API level 28) and iOS (version 13.1) platforms and it works for both:

import 'dart:async';

import 'package:flutter/material.dart';

import 'package:flutter_inappwebview/flutter_inappwebview.dart';

Future main() async {
  runApp(new MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {

  @override
  void initState() {
    super.initState();
  }

  @override
  void dispose() {
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: InAppWebViewPage()
    );
  }
}

class InAppWebViewPage extends StatefulWidget {
  @override
  _InAppWebViewPageState createState() => new _InAppWebViewPageState();
}

class _InAppWebViewPageState extends State<InAppWebViewPage> {
  InAppWebViewController webView;
  final CookieManager cookieManager = CookieManager.instance();

  @override
  void initState() {
    super.initState();

    var expiresDate = DateTime.parse("2019-09-30 00:00:00.000").millisecondsSinceEpoch;
    cookieManager.setCookie(url: "https://flutter.dev", name: "myToken", value: "wertygubnm5046rhndf", domain: ".flutter.dev", expiresDate: expiresDate);
    cookieManager.setCookie(url: "https://flutter.dev", name: "myCookie", value: "myValue", domain: ".flutter.dev", expiresDate: expiresDate);
    cookieManager.setCookie(url: "https://flutter.dev", name: "myCookie2", value: "myValue2");
  }

  @override
  Widget build(BuildContext context) {

    return Scaffold(
        appBar: AppBar(
            title: Text("InAppWebView")
        ),
        body: SafeArea(
            child: Column(children: <Widget>[
              Expanded(
                child: Container(
                  child: InAppWebView(
                    initialUrl: "https://flutter.dev",

                        debuggingEnabled: true,
                      )
                    ),
                    onWebViewCreated: (InAppWebViewController controller) {
                      webView = controller;
                    },
                    onLoadStart: (InAppWebViewController controller, String url) {

                    },
                    onLoadStop: (InAppWebViewController controller, String url) async {
                      print(await controller.evaluateJavascript(source: "document.cookie"));
                    },
                  ),
                ),
              ),
              ButtonBar(
                alignment: MainAxisAlignment.center,
                children: <Widget>[
                  RaisedButton(
                    child: Icon(Icons.arrow_back),
                    onPressed: () {
                      if (webView != null) {
                        webView.goBack();
                      }
                    },
                  ),
                  RaisedButton(
                    child: Icon(Icons.arrow_forward),
                    onPressed: () {
                      if (webView != null) {
                        webView.goForward();
                      }
                    },
                  ),
                  RaisedButton(
                    child: Icon(Icons.refresh),
                    onPressed: () {
                      if (webView != null) {
                        webView.reload();
                      }
                    },
                  ),
                ],
              ),
            ]))
    );
  }
}

It prints all of my cookies:

myCookie=myValue; myToken=wertygubnm5046rhndf; myCookie2=myValue2; _ga=GA1.2.919201585.1575042727; _gid=GA1.2.2019611942.1575737332; _gat=1

But I have tried your code for testing again, unfortunately,it still no work.I simply want to set the cookie named "JSESSIONID"。Have you ever tried this key ? I really want to solve the problem, or can you give me your any contact way for me ?

[VincentTung1]

Does the cookieManager must set in the method "initState"?
