问题描述

我可以看到 Android 文档中有两种不同的方法来发布数据和添加标题.

I could see there are two separate methods in Android docs to post the data and add the headers.

For setting Headers
public void loadUrl (String url, Map<String, String> additionalHttpHeaders)


For setting Post Data
public void postUrl (String url, byte[] postData)

但我真正需要的是与标题一起发布数据.(意味着我想要一个同时完成这两个任务的方法?)

But what I really required is to post the data along with headers. ( Means I want a single method which does both the task ? )

谁能帮帮我.

谢谢:)

推荐答案

我最近遇到了同样的问题，几个小时后解决了.

I've bumped on same problem recently and after couple of hours solved it.

这是我的代码片段和一些注释:

Here is my code snippet with some comments:

HttpClient httpclient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(getPostUrl());

// example of adding extra header "Referer"
httpPost.addHeader("Referer", getReferer()); 

ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();

for (PostItem postItem : getPostItems()) { 
    // key value post pairs
    // add post parameters in array list
    postParameters.add(new BasicNameValuePair(postItem.getKey(), postItem.getValue())); 
}

HttpResponse response = null;

try {
    mWebView.getSettings().setJavaScriptEnabled(true);
    httpPost.setEntity(new UrlEncodedFormEntity(postParameters));

    response = httpclient.execute(httpPost);

    BasicResponseHandler responseHandler = new BasicResponseHandler();
    String htmlString = responseHandler.handleResponse(response);

    // important!! is to fill base url
    mWebView.loadDataWithBaseURL(getPostUrl(), htmlString, "text/html", "utf-8", null); 

} catch (Exception e){
    // handle errors
}
