android 6.0 移除了 apache httpclient
为了做兼容，我们必须考虑这个问题，下面推荐几个解决方案
1.使用okhttp、volley
2.官网下载apache httpclient jar包
3.使用HttpURLConnection访问网络。
##这个库是基于HttpURLConnection封装的同步和异步网络请求库。
##异步请求
AsyncHttpCliect cliect = new AsyncHttpCliect();
Map<String, String> map = new HashMap<String, String>();
map.put("ip", "63.223.108.42");
cliect.post("http://ip.taobao.com/service/getIpInfo.php", map, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(HttpResponse response) {
}
});
cliect.get("http://www.baidu.com", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(HttpResponse response) {
}
});同步访问如下： ##同步请求
HttpClient httpClient=new HttpClient();
try {
httpClient.setUserAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36");
httpClient.get("http://www.baidu.com").addParam("name","sunger").addParam("age","22").execute();
} catch (HttpClientException e) {
e.printStackTrace();
} DownloadDelegate downloadDelegate = new DownloadDelegate(this, "http://dldir1.qq.com/weixin/android/weixin625android620.apk", "/sdcard/a/", new DownloadHandler() {
@Override
protected void onFinish(String msg) {
}
@Override
public void onError(String msg) {
}
@Override
protected void onSpeed(String speed) {
}
});
//开始下载
downloadDelegate.start();
//暂停下载
downloadDelegate.pause(); AsyncHttpCliect cliect = new AsyncHttpCliect();
try {
cliect.setCertificates(getAssets().open("srca.cer"));
} catch (IOException e) {
e.printStackTrace();
}
cliect.get("https://kyfw.12306.cn/otn/", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(HttpResponse response) {
Log.d("-----HttpResponse--", response.getStatusCode() + "");
}
@Override
public void onFailure(Throwable error) {
Log.d("-----Error--", error.getMessage());
}
});下一次更新将实现HttpResponseCacheHttp缓存功能
