我正在努力不只是使用catch(Exception e) {e.printStackTrace();}
并让应用程序的用户更清楚地了解我的应用程序失败的原因。
因此,我想检测是否抛出了给定的服务器错误,例如Http 500错误。
目前,我的代码正在抛出堆栈跟踪:
java.io.IOException: Server returned HTTP response code: 500
在下面的catch块中:
public static void main(String args[]) {
try {
DOMParser parser = new DOMParser();
String UrlToParse = "theurlishereinmycode.com";
parser.parse(UrlToParse);
Document doc = parser.getDocument();
// Get the document's root XML node
NodeList PGRoot = doc.getChildNodes();
// Navigate down the hierarchy to get to the program node
Node comp = getNode("ProgramGuideWCSResponse", PGRoot);
Node PG = getNode("programGuide", comp.getChildNodes() );
Node Programs = getNode("programs", PG.getChildNodes() );
Node IndivdualProgram = getNode("program", Programs.getChildNodes() );
//String execType = getNodeAttr("programTitle", exec);
// Load the executive's data from the XML
NodeList nodes = IndivdualProgram.getChildNodes();
String showTitleAttr = getNodeValue("programTitle", nodes);
// check to make sure the fetched Show Title isn't: 1) null or 2) blank
// if it is... display the default value for title.
// else, print the Program Title.
if(showTitleAttr == null || showTitleAttr == ""){
System.out.println("You’re watching XX Plus");
}
else{
System.out.println("Program title is: " + showTitleAttr);
}
}
catch ( Exception e ) {
e.printStackTrace();
}
}
如何为内部服务器错误记录HTTP 500错误?
谢谢
