我有一个表单的消息构造函数方法:
public static String constructMsg(CustomerInfo customer) {
... snipped
String msg = String.format("Snipped code encapsulated by customer object");
return msg;
}
API链接是:
http://xxx.xxx.xx.xx:8080/bulksms?username=xxxxxxx& password = xxxx& type = 0& dlr = 1& destination = 10digitno&源= XXXXXX&安培;消息= XXXXX
在我的主要方法中我有:
List<CustomerInfo> customer = dao.getSmsDetails(userDate);
theLogger.info("Total No : " + customer.size() );
if (!customer.isEmpty()) {
for (CustomerInfo cust : customer) {
String message = constructMsg(cust);
// Add link and '?' and query string
// use URLConnection's connect method
}
}
所以我使用了URLConnection的connect
方法。 API没有任何文档。有没有办法检查回复?
我的另一个问题是,我被建议使用ThreadPoolExecutor。我如何在这里使用它?

此方法使用HTTPURLConnection执行GET请求,将响应作为String返回。有很多方法可以做到这一点,这不是特别精彩,但它真的可读。
public String getResponse(String url, int timeout) {
HttpURLConnection c;
try {
URL u = new URL(url);
c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setRequestProperty("Content-length", "0");
c.setUseCaches(false);
c.setAllowUserInteraction(false);
c.setConnectTimeout(timeout);
c.setReadTimeout(timeout);
c.connect();
int status = c.getResponseCode();
switch (status) {
case 200:
case 201:
BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line+"\n");
}
br.close();
return sb.toString();
default:
return "HTTP CODE: "+status;
}
} catch (MalformedURLException ex) {
Logger.getLogger(DebugServer.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(DebugServer.class.getName()).log(Level.SEVERE, null, ex);
} finally{
if(c!=null) c.disconnect();
}
return null;
}
像这样调用这个方法:
getResponse("http://xxx.xxx.xx.xx:8080/bulksms?username=xxxxxxx&password=xxxx&type=0 &dlr=1&destination=10digitno&source=xxxxxx&message=xxxxx",2000);
我认为你的URL中的空格不应该在那里。
