Axios pass an array as problems get request? Hk []=[1, 2, 3]-CodePudding

Axios use get the params transfer directly into an array of

I write so

 
Var nk=[1, 2, 3] 
Axios. Get (urlStr, {
Params: {
Hk: nk 
} 
})

Single request url is joining together for localhost: 8080/API/? Hk []=[1, 2, 3]
Turned into a 400 illegal format how to splice it into the right localhost: 8080/API/? Hk=1 & amp; Hk=2 & amp; Nk=3

Thank you all for this problem has been bothering me for days

This is handle by yourself, don't put params went inside, his hand in the url to deal with the

 
Var nk=[1, 2, 3] 
UrlStr +=? 
Nk. ForEach (e=& gt; {
UrlStr +="hk=" + e + "& amp;" 
}) 
UrlStr=urlStr. Replace (/& amp; $/, "") 
Axios. Get (urlStr)

CodePudding user response:

Upstairs + 1, qs library perfect solution, it is very convenient,
In addition, why don't want to get? A heap of url doesn't look good, do not post directly to send json his sweet?
Finally, provide a way:

 
Let arr=[1, 2, 3]; 
Let the result='? '+ arr. The map ((item, index)=& gt; ` item ${index}=${item} `). Join (' & amp; '); 
console.log(result);//output is'? Item1=1 & amp; Item2=2 & amp; Item3=3 '
