I have a problem in my code
void getItembyID(String code){
String site;
site = "http:/www.sprii.net/db/getItem.php?pid="+code+"/";
URL url = new URL(site);
}
I get an exception in the third line while writing in IntelliJ. The problem is with URL url = new URL(site);
Should I just try/catch it? Why does it happen? I tried inputting "http://www.google.com/"
to see if it works with that and it still gives me the same exception
EDIT: I realised I have an error in my site name. It misses // after http:. However, after changing that I still get "java.net.MalformedURLException"
I realised what the problem was. This error means that the method I'm calling is declared with throws
and because of that has to be handled with try{}catch(){}
or by adding an identical throws
Make sure String code
does not have any spaces, if you should encode it before appending
I got a similar error when I sent the below URL
String unEncodedUrl = " https://yXXXXXXdh.execute-api.us-east-1.amazonaws.com/prod/helloWorld?date=29 Dec 2017";
URL url = new URL(unEncodedUrl);
the above line has thrown error because there are spaces in the date url query value
so you can solve it by encoding the date value
String encodedUrl = " https://yXXXXXXdh.execute-api.us-east-1.amazonaws.com/prod/helloWorld?date= "+URLEncoder.encode(finaldate,"utf-8");
note: do not encode the entire URL only encode the part which contains spaces
You are missing a /
Try using " http://www.sprii.net/db/getItem.php?pid= "
Perhaps you should expand this function so you can see more errors if they occur, like the code below. (By the way, this executes for me, but I don't know any valid "code" value for the argument)
public void getItembyID(String code) {
String site;
site = "http://www.sprii.net/db/getItem.php?pid=" + code + "/";
try {
URL url = new URL(site);
} catch (MalformedURLException e) {
System.out.println("Error: " + e.getMessage());
e.printStackTrace();
}
}
You are missing a / in the url. Should be http://
