带参数的 URL GET 请求

Question

For example I have this string:

String url = "http://lookup.dbpedia.org/api/search.asmx/KeywordSearch?username=USERNAME&password=PASSWORD";

and I have the String USERNAME="123456" and String PASSWORD="123"; When I make the URL GET request how do I inject the USERNAME and PASSWORD into the URL?

Answer 1

You can just use the Replace function.

This will give you the following code:

String url = "http://lookup.dbpedia.org/api/search.asmx/KeywordSearch?username=USERNAME&password=PASSWORD";
String USERNAME="123456";
String PASSWORD="123";

url = url.replace("?username=USERNAME&password=PASSWORD","username="+USERNAME+"&password="+PASSWORD);

Although it doesn't seem wise to send a Username and Password in the querystring! If no other option is available be sure to use https so this is not visible for sniffing tools. Otherwise use the default authentication.

Answer 2

You can create a method like below

public String getUrl(String Username,String Password){
    String url = "http://lookup.dbpedia.org/api/search.asmx/KeywordSearch?username="+Username+"&password="+Password;
    return url;
}

After that you can call this method

String URL = getUrl("Username","Password");
