如何以字符串形式获取 HTTP 响应正文? [英] How can I get an HTTP response body as a string?
问题描述
我知道曾经有一种方法可以通过 Apache Commons 获取它,如下所述:
I know there used to be a way to get it with Apache Commons as documented here:
http://hc.apache.org/httpclient-legacy/apidocs/org/apache/commons/httpclient/HttpMethod.html
...这里有一个例子:
...and an example here:
http://www.kodejava.org/examples/416.html
...但我相信这已被弃用.
...but I believe this is deprecated.
有没有其他方法可以在 Java 中发出 http get 请求并将响应正文作为字符串而不是流获取?
Is there any other way to make an http get request in Java and get the response body as a string and not a stream?
推荐答案
我能想到的每个库都返回一个流.你可以使用 IOUtils.toString()
来自 Apache CommonsIO 在一个方法调用中将 InputStream
读入 String
.例如:
Every library I can think of returns a stream. You could use IOUtils.toString()
from Apache Commons IO to read an InputStream
into a String
in one method call. E.g.:
URL url = new URL("http://www.example.com/");
URLConnection con = url.openConnection();
InputStream in = con.getInputStream();
String encoding = con.getContentEncoding();
encoding = encoding == null ? "UTF-8" : encoding;
String body = IOUtils.toString(in, encoding);
System.out.println(body);
更新:我更改了上面的示例以使用响应中的内容编码(如果可用).否则它会默认为 UTF-8 作为最佳猜测,而不是使用本地系统默认值.
Update: I changed the example above to use the content encoding from the response if available. Otherwise it'll default to UTF-8 as a best guess, instead of using the local system default.
