我正在使用 pyral，Rally python SDK，我用一个元组格式化我的查询字符串，但似乎任何时候我有两个以上的术语它都会失败。这是我的测试代码：

import pyral

rally = pyral.Rally('rally1.rallydev.com', 'user@example.com', 'password')

user = rally.getUserInfo(name='User Name').pop(0)
wksp = rally.getWorkspace()
proj = rally.getProject()

print user.FirstName, user.LastName
print wksp.Name
print proj.Name

queryStrings = (
('State != "Closed"', 'Owner = ' + user.ref),
('State != "Fixed"', 'Owner = ' + user.ref),
('State != "Closed"', 'State != "Fixed"'),
('State != "Closed"', 'State != "Fixed"', 'Owner = ' + user.ref),
('State != Closed', 'State != Fixed', 'State != Submitted'),
('State != Fixed', 'ScheduleState != Tested'),
('State != Fixed', 'Owner = ' + user.ref, 'ScheduleState != Tested'),
)

for query in queryStrings:
    print "++++++++++++++++++++++++++++++++++++++++++"
    print "Query:",query
    defects = rally.get("Defect", True, query=query)
    print "Number of results:",defects.resultCount
    print "Errors:", defects.errors
    print

这是结果输出

User Name
A Workspace
Web Project
++++++++++++++++++++++++++++++++++++++++++
Query: ('State != "Closed"', u'Owner = user/1234567890')
QUERYJUNK: ((State != "Closed") AND (Owner = user/1234567890))
Number of results: 25
Errors: []

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != "Fixed"', u'Owner = user/1234567890')
QUERYJUNK: ((State != "Fixed") AND (Owner = user/1234567890))
Number of results: 89
Errors: []

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != "Closed"', 'State != "Fixed"')
QUERYJUNK: ((State != "Closed") AND (State != "Fixed"))
Number of results: 149
Errors: []

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != "Closed"', 'State != "Fixed"', u'Owner = user/1234567890')
QUERYJUNK: ((State != "Closed") AND (State != "Fixed") AND (Owner = user/1234567890))
Number of results: 0
Errors: [u'Could not parse: Error parsing expression -- expected ")" but saw "AND"       instead.']

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != Closed', 'State != Fixed', 'State != Submitted')
QUERYJUNK: ((State != Closed) AND (State != Fixed) AND (State != Submitted))
Number of results: 0
Errors: [u'Could not parse: Error parsing expression -- expected ")" but saw "AND" instead.']

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != Fixed', 'ScheduleState != Tested')
QUERYJUNK: ((State != Fixed) AND (ScheduleState != Tested))
Number of results: 247
Errors: []

++++++++++++++++++++++++++++++++++++++++++
Query: ('State != Fixed', u'Owner = user/1234567890', 'ScheduleState != Tested')
QUERYJUNK: ((State != Fixed) AND (Owner = user/1234567890) AND (ScheduleState !=     Tested))
Number of results: 0
Errors: [u'Could not parse: Error parsing expression -- expected ")" but saw "AND" instead.']

QUERYJUNK 是 Rally SDK 本身构建的查询字符串的输出，然后将其发送到拉力赛服务。

编辑：

由于根据 Kyle 的回答，这是 SDK 本身的一个错误，因此我在脚本中创建了一个解决方法，直到可以修复 SDK。

def buildQueryString(querySequence):
if type(query) in [types.ListType, types.TupleType]:
    seq = ["(%s)" % (s,) for s in querySequence]
    qs = "%s" % seq.pop(0)
    for qt in seq:
        qs = "(%s AND %s)" % (qs, qt)
    print "QS:",qs
    return qs

return querySequence

然后我将生成的这个字符串传递给 API，现在一切似乎都正常了。看起来 API 还支持查询参数的字典，但由于它没有记录，而且我不需要它，我没有为这种情况创建解决方法。

这似乎是 pyral 生成具有超过 2 个子句的查询字符串的错误。

目前：

((State != Closed) AND (State != Fixed) AND (State != Submitted))

应该：

(((State != Closed) AND (State != Fixed)) AND (State != Submitted))

我们将尽快修复此问题并在 github 上开源，以便社区可以更好地解决此类问题。
