how to get url html contents to string in java
提问by Peyush Goel
I have a html file stored on the server. I have the URL path something like this: <https://localhost:9443/genesis/Receipt/Receipt.html >
我在服务器上存储了一个 html 文件。我有这样的 URL 路径：<https://localhost:9443/genesis/Receipt/Receipt.html >
I want to read the contents of this html file which would contain tags, from the url i.e. the source code of the html file.
我想从 url 中读取这个包含标签的 html 文件的内容，即 html 文件的源代码。
How am I supposed to do this? This is a server side code and can't have a browser object and I am not sure using a URLConnection would be a good option.
我该怎么做？这是一个服务器端代码，不能有浏览器对象，我不确定使用 URLConnection 是否是一个不错的选择。
What should be the best solution now?
现在最好的解决方案应该是什么？

Resolved it using spring added the bean to the spring config file
使用 spring 将 bean 添加到 spring 配置文件中解决了它
<bean id = "receiptTemplate" class="org.springframework.core.io.ClassPathResource">
<constructor-arg value="/WEB-INF/Receipt/Receipt.html"></constructor-arg>
</bean>
then read it in my method
然后在我的方法中阅读它
// read the file into a resource
ClassPathResource fileResource =
(ClassPathResource)context.getApplicationContext().getBean("receiptTemplate");
BufferedReader br = new BufferedReader(new FileReader(fileResource.getFile()));
String line;
StringBuffer sb =
new StringBuffer();
// read contents line by line and store in the string
while ((line =
br.readLine()) != null) {
sb.append(line);
}
br.close();
return sb.toString();

// open the stream and put it into BufferedReader
BufferedReader br = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = br.readLine()) != null) {
System.out.println(inputLine);
}
br.close();
System.out.println("Done");
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

For exemple :
举个例子 ：
URL url = new URL("https://localhost:9443/genesis/Receipt/Receipt.html");
URLConnection con = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String l;
while ((l=in.readLine())!=null) {
System.out.println(l);
}
You could use the inputstream in other ways, not just printing it.
您可以以其他方式使用输入流，而不仅仅是打印它。
Of course if you have the path to the local file, you can also do
当然如果你有本地文件的路径，你也可以这样做
InputStream in = new FileInputStream(new File(yourPath));
