如何在Android中设置JSONParser.makeHttpRequest的连接超时?
我正在使用如何在Android中设置JSONParser.makeHttpRequest的连接超时?,android,httprequest,android-internet,Android,Httprequest,Android Internet,我正在使用JSONParser.makeHttpRequest获取并发布一些数据。当连接缓慢时,需要一段时间才能得到响应,我想将超时限制设置为5秒。我发现了如何设置HttpResponse超时,但无法将其与JSONParser集成 下面是我用于HttpRequest的代码 JSONParser jParser = new JSONParser(); List<NameValuePair> params = new ArrayList<NameValuePair>(); J
JSONParser.makeHttpRequest
获取并发布一些数据。当连接缓慢时,需要一段时间才能得到响应,我想将超时限制设置为5秒。我发现了如何设置HttpResponse超时,但无法将其与JSONParser集成
下面是我用于HttpRequest的代码
JSONParser jParser = new JSONParser();
List<NameValuePair> params = new ArrayList<NameValuePair>();
JSONObject json = jParser.makeHttpRequest(url, "GET", params);
JSONParser-jParser=new-JSONParser();
List params=new ArrayList();
JSONObject json=jParser.makeHttpRequest(url,“GET”,参数);
如果我能从其他地方得到一个代码片段或到另一篇文章的链接,我将不胜感激 您可以使用Asynctask,并在一段时间后停止请求。 参见示例。以下是代码:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
int timeout;
// constructor
public JSONParser() {
timeout = new Values().gettimeout();
}
// function get json from url
// by making HTTP POST or GET method
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
// Making HTTP request
try {
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setSoTimeout(httpParameters, timeout);
// check for request method
if(method == "POST"){
// request method is POST
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
// request method is GET
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
并在中设置de-HttpParams
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
调整代码以实现此目的;) 为什么我没有想到这一点,我已经使用了Asynctask,但不能想到那个非常简单的方法。谢谢都很好。但是当连接超时时会发生什么呢。我没有看到任何处理代码(异常或其他…)。谢谢。这对我来说很有效,因为连接速度较慢,增加请求超时值就可以了。我的应用程序在wifi上运行良好,但在移动数据上崩溃,但当我增加超时时,它工作得非常好。归功于@Tobias S.Lucian
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
