我正在尝试使用像这样的生成的url http://www.viaf.org/viaf/search?query=cql.any+=+%22Jean-Claude%20Moissinac%22&maximumRecords=5&httpAccept=application/json

# successful trial with the URI
urlQuery = u'http://www.viaf.org/viaf/search?query=cql.any%20=%20"Bacache%20Maya"&httpAccept=application%2Fjson&maximumRecords=5'
print(urlQuery)
req = urllib.request.Request(urlQuery)
with urllib.request.urlopen(req) as rep:
print("success")

viafBaseUrl = u"http://www.viaf.org"
viafCommand = u"/viaf/search?"
viafSearchTemplate = u'"__name%20__surname"'
name = u"Bacache"
surname = u"Maya"
searchString = u'cql.any%20=%20' + viafSearchTemplate.replace(u"__surname", surname).replace(u"__name", name)
params = u"query="+searchString+u"&httpAccept=application%2Fjson&maximumRecords=5"
computedQuery = viafBaseUrl + viafCommand + params
print(urlQuery)
if computedQuery==urlQuery:
print("same strings")
req = urllib.request.Request(computedQuery)
with urllib.request.urlopen(req) as rep:
print("success")第一个请求成功，而第二个请求失败，错误如下：

application%2F中在n和%之间有一个隐藏的unicode字符。只要删除它，它应该可以工作。在在第二个print语句中，意外地引用了第一个查询}。在修复print语句之后，计算查询中有一个额外的空间，这一点变得明显。在
urlQuery，而不是{更新了下面的代码，其中包含了修复程序和一些注释：
