我需要覆盖位于我帮助的另一个模块中的stringifyArray Qs.js函数。怎么样?
https://github.com/mikeal/request/blob/master/request.js
示例:
var request = require('request');
request.qs.stringifyArray = function (arr, prefix) {
var ret = [];
if (!prefix) throw new TypeError('stringify expects an object');
for (var i = 0; i < arr.length; i++) {
ret.push(this.stringify(arr[i], prefix));
}
return ret.join('&');
};`
答案 0 :(得分:0)
我的解决方案是覆盖(request.Request.prototype.qs)
var qs = require('qs'),
request = require('request'),
url = require('url');
var stringify;
var toString = Object.prototype.toString;
var isArray = Array.isArray || function (arr) {
return toString.call(arr) === '[object Array]';
};
var objectKeys = Object.keys || function (obj) {
var ret = [];
for (var key in obj) {
if (obj.hasOwnProperty(key)) {
ret.push(key);
}
}
return ret;
};
var stringifyString = function (str, prefix) {
if (!prefix) throw new TypeError('stringify expects an object');
return prefix + '=' + encodeURIComponent(str);
};
var stringifyArray = function (arr, prefix) {
var ret = [];
if (!prefix) throw new TypeError('stringify expects an object');
for (var i = 0; i < arr.length; i++) {
ret.push(stringify(arr[i], prefix));
}
return ret.join('&');
};
function stringifyObject(obj, prefix) {
var ret = [];
var keys = objectKeys(obj);
var key;
for (var i = 0, len = keys.length; i < len; ++i) {
key = keys[i];
if ('' === key) {
continue;
}
if (null === obj[key]) {
ret.push(encodeURIComponent(key) + '=');
} else {
ret.push(stringify(obj[key], prefix ? prefix + '[' + encodeURIComponent(key) + ']' : encodeURIComponent(key)));
}
}
return ret.join('&');
}
stringify = function (obj, prefix) {
if (isArray(obj)) {
return stringifyArray(obj, prefix);
} else if ('[object Object]' === toString.call(obj)) {
return stringifyObject(obj, prefix);
} else if ('string' === typeof obj) {
return stringifyString(obj, prefix);
} else {
return prefix + '=' + encodeURIComponent(String(obj));
}
};
并覆盖prototype.qs:
request.Request.prototype.qs = function (q, clobber) {
var base;
if (!clobber && this.uri.query) {
base = qs.parse(this.uri.query)
}
else {
base = {}
}
for (var i in q) {
base[i] = q[i]
}
if (stringify(base) === '') {
return this
}
this.uri = url.parse(this.uri.href.split('?')[0] + '?' + stringify(base));
this.url = this.uri;
this.path = this.uri.path;
return this;
};
