Please help me to resolve this issue..

What I have tried:

URLConnection connection = new URL("http://localhost:8080/Core/sr/main/java/com/service/mailutil/impl/EmailContent.html").openConnection();
			connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
			connection.connect();

			BufferedReader r  = new BufferedReader(new InputStreamReader(connection.getInputStream(), Charset.forName("UTF-8")));

			StringBuilder sb = new StringBuilder();
			String line;
			while ((line = r.readLine()) != null) {
			    sb.append(line);
			}

当我直接在浏览器中运行网址时，它会在页面上显示以下信息。

when i directly run the url in the browser it is showing following message..on the page.

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Forbidden, status=403).
Access Denied

推荐答案

好吧，错误信息是不言自明的。网址无法访问...因此，您必须查看网址。



如果您确定网址是正确的，请尝试使用此解决方案：

Well, an error message is self-explanatory. An url is not accessible... So, you have to check out url address.

If you're sure that url address is correct, try to use this solution:

引用：

而不是在java中使用URLConnection，如果你使用HttpURLConnection，你应该可以从java访问所请求的网页。请尝试以下代码：

nstead of using URLConnection in java, if you use HttpURLConnection you should beable to access the requested web page from java. Try the following code:

HttpURLConnection httpcon = (HttpURLConnection) url.openConnection(); 
 httpcon.addRequestProperty("User-Agent", "Mozilla/4.76");

使用urlConnection的普通java不会被接受访问互联网。要访问浏览器，它需要执行搜索而不需要HTTP响应代码：403 for URL

Normal java using urlConnection wont be accepted to access the internet. To access the browser it will need to perform a search without theexception HTTP response code : 403 for URL

并根据您的需要进行更改。
