Method description:

Convert the object into a string. Multiple parameters in the string will be separated by ‘&’ and assigned with ‘=’.

The operation of this function is opposite to querystring.parse() . You can understand it by looking at the example.

Grammar:

Copy code The code is as follows:

querystring.stringify(obj, [sep], [eq])

Receive parameters:

obj The object to be converted
sep Set the separator, the default is '&'
eq                                                                                                                                               out out out of 5

Example:

Copy code The code is as follows:
querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' })
// returns
'foo=bar&baz=qux&baz=quux&corge='

querystring.stringify({foo: 'bar', baz: 'qux'}, ';', ':')
// returns
'foo:bar;baz:qux'

Source code:

Copy code The code is as follows:
QueryString.stringify = QueryString.encode = function(obj, sep, eq, name) {
sep = sep || '&';
eq = eq || '=';
if (util.isNull(obj)) {
Obj = undefined;
}
if (util.isObject(obj)) {
Return Object.keys(obj).map(function(k) {
var ks = QueryString.escape(stringifyPrimitive(k)) eq;
If (util.isArray(obj[k])) {
          return obj[k].map(function(v) {
              return ks QueryString.escape(stringifyPrimitive(v));
           }).join(sep);
} else {
            return ks QueryString.escape(stringifyPrimitive(obj[k]));
}
}).join(sep);
}
if (!name) return '';
return QueryString.escape(stringifyPrimitive(name)) eq
QueryString.escape(stringifyPrimitive(obj));
};
