Question

我正在尝试从网址请求数据，但不断获取404 error

session = requests.Session()
GET = session.get("http://www.inmet.gov.br/sonabra/pg_dspDadosCodigo_sim.php?QTgwNA==", timeout=1)
GET.raise_for_status()

soup = bs4.BeautifulSoup(GET.text, 'html.parser')
imgNumber  = soup.img.get("src").split("imgNum=", maxsplit=1)[1]
decodeNumber = str(base64.b64decode(imgNumber), 'utf-8')

request = {"dtaini": self.start, "aleaValue": imgNumber,
                  "aleaNum": decodeNumber, "dtafim": self.end}

POST = session.post(stationURL, data=request)
POST.raise_for_status()

记录结果：

urllib3.connectionpool: DEBUG: Starting new HTTP connection (1): www.inmet.gov.br
urllib3.connectionpool: DEBUG: http://www.inmet.gov.br:80 "GET /sonabra/pg_dspDadosCodigo_sim.php?QTgwNA==  HTTP/1.1" 200 690
urllib3.connectionpool: DEBUG: /sonabra/pg_dspDadosCodigo_sim.php?QTgwNA==  HTTP/1.1" 302 498
urllib3.connectionpool: DEBUG: http://www.inmet.gov.br:80 "GET /sonabra/log2/index.php HTTP/1.1" 404 302

我不确定发生了什么，因为它曾在几个月前工作，请求在浏览器上运行。我感谢任何帮助或建议。

Answer 1

它与python无关我甚至通过使用网络浏览器获得404尝试不同的URL或联系服务器所有者，如果你认为这不应该发生。

Answer 2

由于某些原因，我在调试中显示混乱，在Chrome和Firefox中显示旧表单，因此表单数据界面改为：

request = {"dtaini": self.start, "aleaValue": imgNumber,
           "aleaNum": decodeNumber, "dtafim": self.end}

为：

request = {"aleaValue": aleaValue, "xaleaValue": xaleaValue,
           "aleaNum": aleaNum, "xID": xID,
           "dtaini": self.start, "dtafim": self.end}

我对有类似问题的人的建议是休息一下，第二天早上用咖啡看东西更好......

Python请求响应错误的url
