如何从请求响应中提取 HTTP 错误文本？
[英]How to extract the HTTP error text from a requests response?
问题描述
I have the following code:
我有以下代码：
tries = 10
for n in range(tries):
try:
....
responsedata = requests.get(url, data=data, headers=self.hed, verify=False)
responsedata.raise_for_status()
..
if .... :
break #exit loop condition
except (ChunkedEncodingError, requests.exceptions.HTTPError) as e:
print ("page #{0} run #{1} failed. Returned status code {2}. Msg: {3}. Retry.".format(page, n, responsedata.status_code, sys.exc_info()[0]))
if n == tries - 1:
raise e # exit the process
The prints I see are:我看到的印刷品是：
page #53 run #0 failed. Returned status code 502. Msg: <class 'requests.exceptions.HTTPError'>. Retry.
page #1 run #1 failed. Returned status code 500. Msg: <class 'requests.exceptions.ChunkedEncodingError'>. Retry.
While this is Ok it doesn't give me actual information about the problem.虽然这很好，但它并没有给我关于这个问题的实际信息。 The message just tell me the exception title.该消息只是告诉我异常标题。
If I print the: responsedata.text when exception happens I see:如果我在异常发生时打印： responsedata.text ，我会看到：
Returned status code 502. Message is: ...
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
<title>502 - Web server received an invalid response while acting as a gateway or proxy server.</title>
<style type="text/css">
<!--
body{margin:0;font-size:.7em;font-family:Verdana, Arial, Helvetica, sans-serif;background:#EEEEEE;}
fieldset{padding:0 15px 10px 15px;}
h1{font-size:2.4em;margin:0;color:#FFF;}
h2{font-size:1.7em;margin:0;color:#CC0000;}
h3{font-size:1.2em;margin:10px 0 0 0;color:#000000;}
#header{width:96%;margin:0 0 0 0;padding:6px 2% 6px 2%;font-family:"trebuchet MS", Verdana, sans-serif;color:#FFF;
background-color:#555555;}
#content{margin:0 0 0 2%;position:relative;}
.content-container{background:#FFF;width:96%;margin-top:8px;padding:10px;position:relative;}
-->
</style>
</head>
<body>
...
This is a giant message most of it is garbage but it also says: 502 - Web server received an invalid response while acting as a gateway or proxy server.这是一个巨大的消息，其中大部分是垃圾，但它也说： 502 - Web server received an invalid response while acting as a gateway or proxy server. can I access this message and also print it to my log?我可以访问此消息并将其打印到我的日志中吗？

您可以使用responsedata.status_code及其文本描述通过responsedata.reason访问响应的状态代码（请参阅http://docs.python-requests.org/en/master/api/中的更多内容）

If your endpoint returns a detailed, application-specific error message in the response body, you can make use of the fact that a requests HTTPError retains a reference to the Response that caused it to be raised:如果您的端点在响应正文中返回详细的、特定于应用程序的错误消息，您可以利用以下事实：请求HTTPError保留对导致它被引发的Response的引用：
from requests.exceptions import HTTPError
try:
# Some code that makes requests
except HTTPError as e:
print(e.response.text)
