我正在尝试使用java在某些网站上发出GET AJAX请求。
我的代码如下:
String cookie = getRandomString(16); //Getting a random 32-symbol string
String url = "https://e-kassa.org/core/ajax/stations_search.php?"
+ "q=%D0%BE&limit=10×tamp=1352028872503";
HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
conn.setRequestProperty("Cookie", "PHPSESSID=" + cookie);
InputStream is = conn.getInputStream();
int buffer;
while((buffer = is.read()) != -1)
System.out.print(buffer);
is.close();
conn.disconnect();
但问题是没有什么可以从InputStream下载的。但如果我使用我的浏览器做同样的事情,我会得到一个响应,由以下格式的文本行组成:
CITY_NAME | SOME_DIGITS
那么,任何人都能告诉我,我怎样才能以适当的方式提出这样的要求呢?
UPD:没有cookie我有相同的行为(在浏览器中一切都很好,但不是用Java)。

请你试试:
BufferedReader rd = null;
try {
URL url = new URL("https://e-kassa.org/core/ajax/stations_search.php?"
+ "q=%D0%BE&limit=10×tamp=1352028872503");
URLConnection conn = url.openConnection();
String cookie = (new RandomString(32)).nextString();
conn.setRequestProperty("Cookie", "PHPSESSID=" + cookie);
// Get the response
rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = rd.readLine()) != null) {
sb.append(line);
}
System.out.println(sb.toString());
} catch (Exception e) {
e.printStackTrace();
} finally {
if (rd != null) {
try {
rd.close();
} catch (IOException e) {
}
}
}
这是在我的项目中正常运行的代码的和平。 :)

尝试以下方法。
HttpURLConnection connection = null;
try {
String url = "https://e-kassa.org/core/ajax/stations_search.php?"
+ "q=%D0%BE&limit=10×tamp=1352028872503";
URL url = new URL(url);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("Cookie", "PHPSESSID=" + cookie);
connection.connect();
connection.getInputStream();
int buffer;
while((buffer = is.read()) != -1)
System.out.print(buffer);
} catch (MalformedURLException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
} finally {
if(null != connection) { connection.disconnect(); }
}
