在browsermob-proxy-api模块中使用 addURLWhiteList 时出现服务器错误：500。我使用的是 Node JS 和量角器。我想仅从相关 URL 生成信息，因为如果所有第三方服务流量也包含在 HAR 文件中，生成的 HAR 文件的大小将变得太大。这是我的代码：-
(conf.js)
/* global exports, require, jasmine, browser */
var Proxy = require('browsermob-proxy-api'),
Q = require('q');
exports.config = {
chromeOnly: true,
capabilities: {
browserName: 'chrome',
proxy: {
proxyType: 'manual',
httpProxy: 'localhost:8888',
sslProxy: 'localhost:8888'
}
},
specs: ['abcd'],
onPrepare: function () {
(spec.js)
/* global describe, beforeEach, afterEach, it, console, browser, element, expect
*/
var fs = require('fs');
var date = new Date();
describe('Angular Homepage', function () {
beforeEach(function (done) {
console.log('beforeEach');
console.log('browser.params.proxy', browser.params.proxy);
console.log('browser.params.proxyData', browser.params.proxyData);
browser.params.proxy.createHAR(8888, { 'initialPageRef': 'foo', 'captureContent': 'true' });
browser.params.proxy.addURLWhiteList(8888, 'http://abcd.com',function (err) {
if(err) {
return console.log("white list error" + err);
}
});
});
afterEach(function (done) {
console.log('afterEach');
browser.params.proxy.getHAR(8888, function (err, harData) {
// console.log('harData', harData);
fs.writeFile("C:\Protractor\p1" + Date.now() + ".har", harData, function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});
done();
});
});
现在，当我运行此代码时，我从 addURLWhiteList 方法收到此错误。

我是新手。谁能告诉我如何解决这个错误？
