jspにプロキシコードを書くことで、自分のコンピュータからローカルに他のドメインにajaxを呼び出そうとしています。これが私のjQuery AJAXコードで、proxy.jspページを呼び出しています。publicIdとsystemIdの間に空白が必要です
var metadata = 'https://rest-search.host.com/machine/search/meta?id=';
var on_show_info= function() {
var AjaxCall = data + current_doc_info.id;
alert(AjaxCall);
request_meta_info = $.ajax({
url: "proxy.jsp?url=" + AjaxCall,
type: 'GET',
success: check,
error: error
});
};
そして、私のJSPファイルがある： -
<%@ page language="java" import="org.w3c.dom.*,javax.xml.parsers.DocumentBuilder,javax.xml.parsers.DocumentBuilderFactory,java.net.*,java.io.*" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%
String urlToQuery = request.getParameter("url");
System.out.println("rj " +urlToQuery);
URL url = new URL(urlToQuery);
final String login ="user";
final String password ="pass";
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication (login, password.toCharArray());
}
});
URLConnection conn = url.openConnection();
InputStream in = conn.getInputStream();
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db =dbf.newDocumentBuilder();
Document doc=db.parse(urlToQuery);
NodeList nl= doc.getElementsByTagName("attr");
%>
<%= nl.item(0).getFirstChild().getNodeValue() %>
そして、私は応答をチェックすると、私はそれを解析しているXMLファイルに対してこのエラーを取得しています：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 White spaces are required between publicId and systemId.</title>

何wrオング、私は任意の提案は...
このエラーを無視するためにJavaを取得するには離れていますか？ –
