问题描述
CASE1 ...,其中validatebody(schemas.authschema)返回的函数作为中间件执行...
router.route("/signup").post(validatebody(schemas.authschema),userscontrollers.signup);
module.exports={
validatebody:function(schema)
{
return function(req,res,next)
{
var result=joi.validate(req.body,schema);
if(result.error)
return res.status(400).json(result.error);
if(!req.value)
req.value={};
req.value['body']=result.value;
next();
}
},schemas:{
authschema:joi.object().keys(
{
email:joi.string().email().required(),password:joi.string().required()
})
}
};
现在第二种情况....在这种情况下,我什么也不会输出,并且页面会继续加载很长时间,因为函数名称从不调用第二个函数,也不会触发next()....但是在第一种情况下case ...返回的函数被调用..
app.get("/users",firstfunction,secondfunction);
function firstfunction()
{
return function(req,next)
{
console.log(req);
next();
}
}
function secondfunction(req,next)
{
res.send("go there");
}
app.listen(3000);
解决方法
您正在传递# Tokenize all sentences in a column
tokenized_sentences = [s.split() for s in df[col]]
# calculate distance between 2 responses using wmd
def find_similar_docs(sentence_1,sentence_2):
distance = model.wv.wmdistance(sentence_1,sentence_2)
return distance
# find response pairs
pairs_sentences = list(combinations(tokenized_sentences,2))
# get all similiarity scores between sentences
list_of_sim = []
for sent_pair in pairs_sentences:
sim_curr_pair = find_similar_docs(sent_pair[0],sent_pair[1])
list_of_sim.append(sim_curr_pair)
,但未调用它。您需要做
firstfunction
