如何在 Flutter WebView 中将数据发布到 URL [英] How to Post Data to URL in Flutter WebView

问题描述

我想将一些数据发布到 Flutter WebView 中的 URL 正文.那么，我该怎么做?

I want to post some data to the URL body in Flutter WebView. So, how can I do it?

推荐答案

webview_flutter 目前没有发送 post 请求的方法.但是，您可以尝试我的 flutter_inappwebview 插件.支持POST请求！

webview_flutter doesn't have a method to send post requests at this moment. However, you can try my flutter_inappwebview plugin. It supports POST requests!

使用flutter_inappwebview的当前最新版本5.0.5+3的简单示例 插件是:

A simple example using the current latest version 5.0.5+3 of the flutter_inappwebview plugin is:

var postData = Uint8List.fromList(utf8.encode("firstname=Foo&lastname=Bar"));
controller.postUrl(url: Uri.parse("https://example.com/my-post-endpoint"), postData: postData);

其中 postData 是 x-www-form-urlencoded 格式的请求正文.

where the postData is the Body of the request in x-www-form-urlencoded format.

例如，如果您有一个 PHP 服务器，您可以像往常一样访问 firstname 和 lastname 值，即 $_POST['firstname'] 和 $_POST['lastname'].

For example, if you have a PHP server, you can access the firstname and lastname values as you normally would do, that is $_POST['firstname'] and $_POST['lastname'].

您还可以使用初始 POST 请求初始化 InAppWebView 小部件，如下所示:

You can also initialize the InAppWebView widget with an initial POST request like this:

child: InAppWebView(
  initialUrlRequest: URLRequest(
    url: Uri.parse("https://example.com/my-post-endpoint"),
    method: 'POST',
    body: Uint8List.fromList(utf8.encode("firstname=Foo&lastname=Bar")),
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    }
  ),
  onWebViewCreated: (controller) {
    
  },
),
