Django 与肥皂水的奇怪行为

Question

我正在使用 suds 来使用 WebService，但我遇到了一个奇怪的错误。

当我第一次调用 WebService 时，它失败了。当我刷新页面时，它也失败了。当我第二次刷新页面时，它起作用了。

你们知道为什么只有在我刷新页面两次时它才有效吗？

urls.py :

url(r'^test/$', views.formulaire),
url(r'^test/(?P<rechercher>.*\d+)/$', views.formulaire), #optional = .*

views.py :

url = 'https://myWebService.com/Action.asmx?WSDL'
username='username'
password='password'

client = Client(url=url, username=username, password=password)

前两次我收到以下消息：

TransportError at /blog/test/
HTTP Error 401: Unauthorized

Exception Type: TransportError at /blog/test/
Exception Value: HTTP Error 401: Unauthorized

Answer 1

由于没有使用正确的 transport class，我在生产之前遇到过同样的问题运行。在我的例子中，对于生产 https 是强制的，而开发是严格的 http。

从 this question -

Suds 提供了两个 HttpAuthenticated classes，一个在 suds.transport.http 模块中，第二个在 suds.transport.https 模块中。看起来你是从 suds.transport.http 实例化的，但是由于你的 URL 是 https://，你可能想尝试 suds.transport.https.HttpAuthenticated.
