android webview点击模拟

发布于 2024-11-09 11:00:39 字数 88 浏览 0 评论 0原文

我想知道是否可以从网站加载框架，填充文本框，按提交按钮并从该页面获取结果？我需要在后台执行此操作，这样我的网络视图就不会显示，只显示编辑文本和文本视图......

你不能使用 http 请求做你提到的事情吗？
你需要 WebView 做什么？

您可以使用 httpGet 获取页面，并使用 httpPost 在用户按下提交时发布结果。您所要做的就是确保帖子包含网页期望的数据，并采用其期望的格式。

检查所需内容的一个好方法是使用 Firefox Live HHTP Headers add on (https://addons.mozilla.org/en-US/firefox/addon/live-http-headers/)。

例如，GET 可能是

URI uri = new URI(<your URL here>);
HttpGet request = new HttpGet(uri);
HttpResponse response = defaultHttpClient.execute(request);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);

然后您在 Android 视图中放置编辑文本框和按钮等。当用户按下“提交”时，您会从编辑文本框中获取文本，然后构造一个 POST，如下所示。

URI uri = new URI(<your URL here - without a host>);
HttpPost request = new HttpPost(urri);
request.setHeader("Content-type", "application/x-www-form-urlencoded");

List<NameValuePair> bodyParams = new ArrayList<NameValuePair>();
bodyParams.add(new BasicNameValuePair(<parameter name string>, <parameter value string>);
// repeat additional bodyParams.add() as necessary for further parameters
request.setEntity(new UrlEncodedFormEntity(bodyParams, HTTP.UTF_8));
HttpHost httpHost = new HttpHost(<your host here>);
HttpResponse response = defaultHttpClient.execute(httpHost, request);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);

You can use httpGet to get the pages and httpPost to post the results when the user presses submit. All you have to do is make sure that the post carries the data that the web page expects, and in the format it expects.

A good way to check what is required is use the Firefox Live HHTP Headers add on (https://addons.mozilla.org/en-US/firefox/addon/live-http-headers/).

For example the GET might be

URI uri = new URI(<your URL here>);
HttpGet request = new HttpGet(uri);
HttpResponse response = defaultHttpClient.execute(request);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);

Then you put up your Android view with edit text boxes and buttons etc. When the user presses Submit, you get the text form the edit text box, and then construct a POST as below.

URI uri = new URI(<your URL here - without a host>);
HttpPost request = new HttpPost(urri);
request.setHeader("Content-type", "application/x-www-form-urlencoded");

List<NameValuePair> bodyParams = new ArrayList<NameValuePair>();
bodyParams.add(new BasicNameValuePair(<parameter name string>, <parameter value string>);
// repeat additional bodyParams.add() as necessary for further parameters
request.setEntity(new UrlEncodedFormEntity(bodyParams, HTTP.UTF_8));
HttpHost httpHost = new HttpHost(<your host here>);
HttpResponse response = defaultHttpClient.execute(httpHost, request);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);
