在Android上发送Post请求和HttpHeaders

Question

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

现在,有不同的方法(来自Android WebView)来做它的一部分,比如:

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

使用指定的其他HTTP标头加载给定的URL.

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.

void postUrl(String url, byte[] postData)

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

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.我错过了什么或我正在尝试的是不可能的？

HttpPost您可以像这样手动执行：

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);

获取response为String：

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();

现在您可以使用以下命令将其html放入：yourWebViewloadData()

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