在Android上将Post请求与HttpHeaders一起发送 [英] Send Post request along with HttpHeaders on Android

问题描述

我需要将数据发布到服务器(带有"referer"标头字段)并在Webview中加载响应.

I need to post data to server (with "referer" header field) and load the response in Webview.

现在，有不同的方法(来自 Android WebView )来完成其中的一部分，就像是这样:

Now, there are different methods (from Android WebView) to do parts of it, like there is:

void loadUrl(String url, Map<String, String> additionalHttpHeaders)

使用指定的其他HTTP标头加载给定的URL.

Loads the given URL with the specified additional HTTP headers.

void loadData(String data, String mimeType, String encoding)

使用数据"方案URL将给定数据加载到此WebView中.

Loads the given data into this WebView using a 'data' scheme URL.

void postUrl(String url, byte[] postData)

使用"POST"方法将带有postData的URL加载到此WebView中.

Loads the URL with postData using "POST" method into this WebView.

loadUrl()允许发送HttpHeaders，但不允许发送post数据，其他方法似乎不允许发送HttpHeaders.我是否缺少某些东西或无法尝试?

loadUrl() allows to send HttpHeaders but doesn't allow to send post data, other methods seem to be not allowing to send HttpHeaders. Am I missing something or what I am trying is not possible?

推荐答案

您可以像这样手动执行 HttpPost :

You can execute the HttpPost manually like this:

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/postreceiver");

// generating your data (AKA parameters)
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("ParameterName", "ParameterValue"));
// ...

// adding your headers
httppost.setHeader("HeaderName", "HeaderValue");
// ...

// adding your data
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse response = httpclient.execute(httppost);

以 String 获取响应:

BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
StringBuilder builder = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
    builder.append(line).append("\n");
}
String html = builder.toString();

现在，您可以使用 loadData()将 html 放入 yourWebView 中:

Now you can put the html into yourWebView by using loadData():

yourWebView.loadData(html ,"text/html", "UTF-8");
