使用 urllib.request 和 json 模块在 Python 中加载 JSON 对象 (#2)

Question

我在 Python 3.2 中的以下代码一直遇到问题，可能是由于一些编码错误。 json.loads-function 给出以下错误消息：“No JSON object could be decoded”。奇怪的是，当我打印出 data_object.decode(encoding) 时，它给出了一个有效的 JSON 对象。代码如下：

req = urllib.request.Request(post_request_url,object_json,request_headers) 
file_response_packet = urllib.request.urlopen(req, timeout=2)   
data_object =  file_response_packet.read()
encoding = file_response_packet.info().get_content_charset('utf-8')
print(encoding)

try:
    print(data_object.decode(encoding))
    test= json.loads(data_object.decode(encoding))
except Exception as e:
    print(str(e))

这是打印出来的：

No JSON object could be decoded

最后一个有趣的评论是，如果我从控制台复制 JSON，将其粘贴到 json.loads-function 并在前后添加 '-characters，它可以完美运行。如果我尝试在 Python 中进行相同的字符串操作，它会一直给我同样的错误。请帮帮我！
