httpurlconnection

问题 I have an app that's custom built for a client and not available in the Play Store that basically makes some network calls when it detects that the device is connected to their WiFi. This should happen even if it has no internet connection, every request that the app makes is to a local address. The problem comes with the new batch of tablets that the client has purchased (Galaxy Tab Active 2, Android 8.1.0, Build number M1AJQ.T395XXU3BRJ5), which will always prefer a connection with internet

问题 Despite that I check a malicious URL (http://fileserver03.com), empty response returns from Google Safe Browsing API v4 . Here is the code I have tried: String postURL = https://safebrowsing.googleapis.com/v4/threatMatches:find?key=API_KEY String requestBody = "{" + " \"client\": {" + " \"clientId\": \"twittersentidetector\"," + " \"clientVersion\": \"1.0\"" + " }," + " \"threatInfo\": {" + " \"threatTypes\": [\"MALWARE\", \"SOCIAL_ENGINEERING\"]," + " \"platformTypes\": [\"ANY_PLATFORM\"],"

问题 I´m trying to get data from a url inside an AsyncTask but I get an error when creating a new instance of HttpUrlConnection . Something like this on Java URL url = new URL("http://www.android.com/"); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); try { InputStream in = new BufferedInputStream(urlConnection.getInputStream()); readStream(in); finally { urlConnection.disconnect(); } But I keep getting the error shown below. class GetWeatherTask : AsyncTast<Void, Void,

问题 I want to compare performances for the three implementations mentioned in the title, I wrote a little JAVA program to help me doing this. The main method contains three blocks of testing, each block looks like this : nb=0; time=0; for (int i = 0; i < 7; i++) { double v = methodX(url); if(v>0){ nb++; time+=v; } } if(nb==0) nb=1; System.out.println("HttpClient : "+(time/ ((double) nb))+". Tries "+nb+"/7"); Variable nb is used to avoid failed requests. Now method methodX is one of : private

问题 I have the following operation which runs every 3 seconds. Basically it downloads a file from a server and save it into a local file every 3 seconds. The following code does the job for a while. public class DownloadTask extends AsyncTask<String, Void, String>{ @Override protected String doInBackground(String... params) { downloadCommandFile( eventUrl); return null; } } private void downloadCommandFile(String dlUrl){ int count; try { URL url = new URL( dlUrl ); NetUtils.trustAllHosts();

问题 So I am trying to add a cookie to a connection. In HTTPUrlConnection, I do the following: HttpURLConnection con; String cookieString = null; con = ((HttpURLConnection) new URL(appUrl).openConnection()); String cookieString = formatCookies("session", userCredential); con.setRequestProperty("Cookie", cookieString); ... I want to do the same in Jersey. So far I have the following: WebTarget wt = client.target(appUrl).path(path); wt.queryParam(..., ...) .request(...) .cookie("session",

问题 I am working on a crawling project. When I do a simple URLConnection connection to the website as shown in below: URLConnection conn = new URL(url).openConnection(); BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream())); The method returns the HTML body correctly. However, the website makes inner requests for some fields. For example, the website fetches the total number of users from a different web service. In the web browser, the total number of users
