Python 3, http.client HTTP памылка 400 (Python 3, http.client HTTP error 400)
I've been working on a small pet project where I am using http.client to communicate (sorry if that's bad terminology, feel free to correct me) with omdbapi. From here I access the data on the website using the following code:
import http.client, json
__connection = http.client.HTTPConnection("www.omdbapi.com")
def getDetailsFromTitle(title):
__connection.request("GET", "/?t=" + title)
return __processRequest()
def getDetailsFromID(id):
__connection.request("GET", "/?i=" + id)
return __processRequest()
def __processRequest():
try:
response = __connection.getresponse()
data = response.read()
data = data.decode("utf‑8")
return json.loads(data)
except: return None
This worked fine for my first few trials, like I was able to get all my data back properly if I looked up say "Eureka", or "Superbad"; however, as soon as I inputted "Bad Kids Go To Hell" my try in __processRequest was being broken and None was being returned. The data I managed to get from the request was:
<!DOCTYPE HTML PUBLIC "‑//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAD><TITLE>Bad Request</TITLE>
<META HTTP‑EQUIV="Content‑Type" Content="text/html; charset=us‑ascii"></HEAD>
<BODY><h2>Bad Request</h2>
<hr><p>HTTP Error 400. The request is badly formed.</p>
</BODY></HTML>
It's obviously breaking on the json.loads(data) as data isn't what is expected, but I'm not overly sure why I'm receiving this error. I went to the website and inputted "Bad Kids Go To Hell" and all worked fine.
Please let me know if you need anything more to assist me, Thank you.

方法 1:
To create the parameter lists of your urls, you should use [urlencode()][1]. In this case it's likely the spaces in the string that causes the problem, they should be converted to '+' characters.
__connection.request("GET", "/"+(urlencode({'t': title})
