我创建了以下用于检查连接状态的函数:
private void checkConnectionStatus() {
HttpClient httpClient = new DefaultHttpClient();
try {
String url = "http://xxx.xxx.xxx.xxx:8000/GaitLink/"
+ strSessionString + "/ConnectionStatus";
Log.d("phobos", "performing get " + url);
HttpGet method = new HttpGet(new URI(url));
HttpResponse response = httpClient.execute(method);
if (response != null) {
String result = getResponse(response.getEntity());
...
当我关闭服务器进行测试时,执行会等待很长时间
HttpResponse response = httpClient.execute(method);
有谁知道如何设置超时以避免等待太久？
谢谢!
我已经有一个Request子类用于http发送到服务器.问题是,我不知道如何为文件添加参数.将字符串发布到服务器很容易.但我需要将文件添加为不同的参数.我该怎么做？
