Node.js

We export a function to rewrite the request url.

wrapUrl(urlStr, options)

urlStr string the url of the API request
options
- reqType string the type of request, like jsonp
- pageUrl string the url of the page
- cookie string the cookie of the page request
- shouldSkip function skip rewritting if returns true. By default, no host or including local will be filtered. Its arguments are:
  - host string the API host

For example, let's make a simple middleware for Koa,

var fetch = require('node-fetch');
var wrapUrl = require('parrot-mocker').wrapUrl;

module.exports = function*(next) {
    this.fetch = (url, options) => {
        return fetch(wrapUrl(url, {
            pageUrl: this.url,
            cookie: this.header.cookie
        }));
    };

    yield* next;
};
