【问题标题】：Plus instead of a space in the url加号而不是网址中的空格

【问题描述】：

我收到一个字符串 url 请求，我想处理它并发送参数，因为它很长。我在req.url 中得到加号，而不是像query 这样的空格。

def getparams(url):
    params = {}
    urlarr = url.split("&")
    i = 0
    while i < len(urlarr):
        params[urllib2.unquote(urlarr[i].split("=")[0].encode("utf-8"))] = urllib2.unquote(urlarr[i].split("=")[1].encode('utf-8'))
        i += 1
    return params
s = Session()
req = s.get(query.split("?")[0], params=getparams(query.split("?")[1]))
print(req.url)

我尝试了decode() 而不是encode() 并且没有encode() 和没有urllib2.unquote()

其中包含很多转义引号。它们都不是空格（%20）

你得到一个加号而不是一个空格的原因是因为你的网址包含一个加号来代替每个空格。这是预期的行为，因为正确的 URL 不应包含任何空格，因此通常会预先转换为“+”。

如果我将您的转义 URL 放入浏览器快捷栏并查看它，我看到的只是“+”，那里没有空格。

这来自您网址开头的某处：

detail_search=1&keywords%5B0%5D%5Bkeys%5D=%D0%9A%D0%BB%D0%B0%D0%B4%D0%BE%D0%B2%D1%89%D0%B8%D0%BA+%D0%9A%D0%BE%D0%BC%D0%BF%D0%BB%D0%B5%D0%BA%D1%82%D0%BE%D0%B2%D1%89%D0%B8%D0%BA

本质上是detail_search=1&keywords[0][keys]=Кладовщик+Комплектовщик 如果没有转义。如您所见，引用和未引用的两个版本都包含加号。这是由网站完成的，不能（不应该）更改，特别是如果您想在其他地方重建 URL。

如果您需要不带加号的参数，只需执行"myUnquotedString".replace("+"," ")（取消引用后，因为我不知道如果urllib2 将格式错误的字符串作为unquote() 的参数会做什么。
