Question

我使用这样的东西发送请求：

from tornado import httpclient
from tornado.httpclient import HTTPRequest

client = httpclient.HTTPClient()
request = HTTPRequest(url='http://google.com/', method="GET")
res = client.fetch(request)
print(res.body)

当HTTP状态为200时工作正常但我想总是得到正文。如何处理？

返回非200 HTTP状态会发生什么？它会抛出异常吗？根据{{3}}文档，这就是发生的事情。真的吗？在这种情况下，你想要做的是：

from tornado import httpclient
from tornado.httpclient import HTTPRequest

    client = httpclient.HTTPClient()
    request = HTTPRequest(url='http://google.com/', method="GET")
    try:
        res = client.fetch(request)
        print(res.body)
    except HTTPError as err:
        res = err.response
        if res:
            print(res.body)

当状态不是200时如何获得身体？
