Question

在db.py中

articles_service = Service()

在controller.py

中

def call():
    """
    exposes services. for example:
    http://..../[app]/articles/call/jsonrpc
    decorate with @services.jsonrpc the functions to expose
    supports xml, json, xmlrpc, jsonrpc, amfrpc, rss, csv
    """
    return articles_service()

@articles_service.json
def article_search():
    # do something with request.post_vars

对app/controller/article_search进行URL调用将引发：

TypeError: article_search() takes no arguments (1 given)

这是在将Web2py从web2py v2.14.6升级到v2.18.2

之后发生的

我想我也许是依赖于早期的Web2py版本中的一个错误，此错误已被关闭。

如果我将参数添加到控制器函数中，例如def article_search(param)，则会引发异常：

TypeError: article_search() got an unexpected keyword argument，后接字典（保留request.post_vars）。

Web2py：调用控制器函数时，得到了意外的关键字参数
