文档移动错误
在阅读了 stackoverflow 上的各种帖子以及其他人的一些帮助后，我在代码中进行了身份验证，并试图避免之前发生的重定向，因为我对所有这些事情都是新手。我开始收到相同的错误 302 Found，文档已移动。
我试图通过在 jsp 中编写一些代理代码来从我的计算机本地对其他域进行 ajax 调用。这是我调用 proxy.jsp 页面的 jQuery AJAX 代码。
var search_agile_metadata = 'https://doc.xyz.com/rest-services/services/get?id=';
var on_show_info = function() {
var outOfDomainCall = search_agile_metadata + current_doc.id;//An XML document
request_meta_info = $.ajax({
url: "proxy.jsp?url=" + outOfDomainCall,
type: 'GET',
success: on_get_metadata,
error: on_get_metadata_error
});
我的 proxy.jsp 文件是：-
<%@ page language="java" import="org.apache.http.impl.client.AbstractHttpClient,
org.apache.http.client.methods.HttpUriRequest,
org.apache.http.client.methods.HttpGet,
org.apache.http.protocol.HttpContext,
org.apache.http.impl.client.DefaultHttpClient,
org.apache.http.HttpResponse

<%
String a_Url = request.getParameter( "url" ) ;
URL url = new URL (a_Url);
String encoding = new String(
org.apache.commons.codec.binary.Base64.encodeBase64
(org.apache.commons.codec.binary.StringUtils.getBytesUtf8("test:test"))
);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setDoOutput(true);
connection.setFollowRedirects(false);
connection.setRequestProperty ("Authorization", "Basic " + encoding);
InputStream content = (InputStream)connection.getInputStream();
BufferedReader in =
new BufferedReader (new InputStreamReader (content));
String line;
while ((line = in.readLine()) != null) {
out.println(line);
}
%>
<%
final HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, false);
%>
当我从服务器收到响应时。我收到这个错误。知道为什么我会收到此错误。

任何帮助将不胜感激。
After reading various post from stackoverflow and some help from other guys I did authentication in my code and also trying to avoid the redirect that was occuring previously as I am new to all these things. I started getting the same error back of 302 Found, document has moved.
I am trying to make a ajax call to other domain locally from my computer by writing some proxy code in jsp. And this is my jQuery AJAX code that is calling proxy.jsp page.
var search_agile_metadata = 'https://doc.xyz.com/rest-services/services/get?id=';
var on_show_info = function() {
var outOfDomainCall = search_agile_metadata + current_doc.id;//An XML document
request_meta_info = $.ajax({
url: "proxy.jsp?url=" + outOfDomainCall,
type: 'GET',
success: on_get_metadata,
error: on_get_metadata_error
});
And my proxy.jsp file is:-
<%@ page language="java" import="org.apache.http.impl.client.AbstractHttpClient,
org.apache.http.client.methods.HttpUriRequest,
org.apache.http.client.methods.HttpGet,
org.apache.http.protocol.HttpContext,
org.apache.http.impl.client.DefaultHttpClient,
org.apache.http.HttpResponse
,org.apache.http.HttpRequest,
java.net.HttpURLConnection,
java.net.URL,
java.util.Collection,
org.apache.commons.httpclient.HttpClient,
org.w3c.dom.*,
javax.xml.parsers.DocumentBuilder,
javax.xml.parsers.DocumentBuilderFactory,
java.net.*,
java.io.*,
org.apache.http.protocol.BasicHttpContext,
org.apache.http.params.BasicHttpParams,
org.apache.http.params.HttpParams,
org.apache.http.Header,
org.apache.http.client.params.HttpClientParams"
contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%
String a_Url = request.getParameter( "url" ) ;
URL url = new URL (a_Url);
String encoding = new String(
org.apache.commons.codec.binary.Base64.encodeBase64
(org.apache.commons.codec.binary.StringUtils.getBytesUtf8("test:test"))
);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setDoOutput(true);
connection.setFollowRedirects(false);
connection.setRequestProperty ("Authorization", "Basic " + encoding);
InputStream content = (InputStream)connection.getInputStream();
BufferedReader in =
new BufferedReader (new InputStreamReader (content));
String line;
while ((line = in.readLine()) != null) {
out.println(line);
}
%>
<%
final HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, false);
%>
And when I get the response back from the server. I get this error. Any idea why I am getting this error back..

我不认为 HTTPS 让你这么麻烦，但 401 Unauthorized 才是关键。检查协议内容： http://www.w3.org /Protocols/rfc2616/rfc2616-sec10.html#sec10.4.2 。您的请求在某种程度上需要考虑授权标头。我过去曾使用 HttpClient 库完成此操作：http://hc。 apache.org/httpclient-3.x/authentication.html
I don't think it is HTTPS that is messing you up so much, but the 401 Unauthorized is the key. Check what the protocol says: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.2 . Your request somehow needs to account for an Authorization header. I've done this in the past with the HttpClient library: http://hc.apache.org/httpclient-3.x/authentication.html
