我对 python 中的 SUDS 有一个奇怪的问题。
我正在编写一个使用 SOAP 服务的应用程序。大约 2 个月的时间里,一切都很顺利。突然间,它停止了工作。这是奇怪的部分。
如果我为我编写的 suds manager 运行 unittest,一切都会顺利进行,并且测试会像往常一样通过。如果我在 GUI 应用程序中运行代码,它会失败,并带有以下回溯:
ERROR:suds.client:<?xml version="1.0" encoding="UTF-8"?>

失败的代码在 GUI 应用程序(PySide)中的线程中运行,相关代码在这里:
class Worker(Thread):
signal = AflafrettirSignal()
def __init__(self, queue, manager, date_from, date_to):
super(Worker, self).__init__()
self.queue = queue
self.manager = manager
self.date_from = date_from
self.date_to = date_to
self.daemon = True
def run(self):
landings = self.manager.get_landings(self.date_from, self.date_to)
for l in landings:
tmp = Landings()
tmp.set_variable(l)
tmp.calc_total_catch()
self.queue.put(tmp)
self.signal.work_done.emit(True)
它在gui中被调用,如下所示:
manager = LandingsManager()
manager.set_credentials(self.username, self.password)
manager.get_client()
worker = Worker(self.queue, manager, date_from, date_to)
worker.start()
最后,这是来自 unittest 模块的代码,它工作正常:
manager = LandingsManager()
manager.set_credentials(usern, passw)
manager.get_client()
data = manager.get_landings('2013-10-01', '2013-10-11')
我已验证设置凭据时的用户名和密码相同,以及调用 get_landings 方法的日期和日期。
就像我说的,这是一个奇怪的问题,我不确定是什么导致它在一个地方失败,而在另一个地方工作。我希望有人能就原因告诉我。
编辑:
我发现出了什么问题。密码包含一个回车,而 SOAP 服务不喜欢这样。
