如何在Android应用程序中的HttpGet方法中添加Header？

问题描述

我看到了许多addHeader（）的例子，但只使用了HttpPost方法。我正在寻找一个在Android应用程序中使用addHeader（）实现HttpGet方法的简单示例。

I saw many examples to addHeader() but only using HttpPost method. I am looking for a simple example having implementation of HttpGet methos with addHeader() in android application.

推荐答案

这是HTTPGET请求的简单示例，并且使用addheader

This is Simple Example with HTTPGET requrest and using with addheader

    public String httpGet(String s) {
    String url = s;
    StringBuilder body = new StringBuilder();
    httpclient = new DefaultHttpClient(); // create new httpClient
    HttpGet httpGet = new HttpGet(url); // create new httpGet object
    httpGet.setHeader("If-Modified-Since","11/26/2012");



    try {
        response = httpclient.execute(httpGet); // execute httpGet
        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        if (statusCode == HttpStatus.SC_OK) {
            // System.out.println(statusLine);
            body.append(statusLine + "\n");
            HttpEntity e = response.getEntity();
            String entity = EntityUtils.toString(e);
            body.append(entity);
        } else {
            body.append(statusLine + "\n");
            // System.out.println(statusLine);
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        httpGet.releaseConnection(); // stop connection
    }
    return body.toString(); // return the String
}
