Android的避免缓存 [英] Android avoid caching

问题描述

// http client
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;

// Checking http request method type
if (method == POST) {
    HttpPost httpPost = new HttpPost(url);
    // adding post params
    if (params != null) {
        httpPost.setEntity(new UrlEncodedFormEntity(params));
    }
    httpResponse = httpClient.execute(httpPost);
} else if (method == GET) {
    // appending params to url
    if (params != null) {
        String paramString = URLEncodedUtils.format(params, "utf-8");
        url += "?" + paramString;
    }
    HttpGet httpGet = new HttpGet(url);
    httpResponse = httpClient.execute(httpGet);
}
httpEntity = httpResponse.getEntity();
response = EntityUtils.toString(httpEntity);

当我做一个服务器调用，它带来的数据...我第二次调用它，它带来的缓存..和不调用服务器...
我该如何解决这个问题？

When I make a server call, it brings data...second time i call it, it brings it cached.. and doesn't call server... how can i fix this?

我不想缓存。

推荐答案

您可以下面的HTTP标头添加到您的要求：的Cache-Control：no-cache的

You can add following HTTP header to your request: Cache-Control: no-cache

httpGet.addHeader("Cache-Control", "no-cache");
