Solution:
解决方案：
module.exports = {
'Check getting log messages' : function (client) {
client
.url('http://jsbin.com/rohilugegi/1/')
.getLogTypes(function(result) {
console.log(result);
})
.getLog('browser', function(result) {
console.log(result);
})
;
return client;
},
It will give output
它会给输出
[Start] Test Suite ================== Running: Check getting log messages [ 'har', 'browser', 'client', 'server' ] [ { message: 'Test error\n error (:0)', timestamp: 1428447687315, level: 'WARNING' }, { message: 'Test log (:)', timestamp: 1428447687315, level: 'INFO' } ] No assertions ran.

Commands getLogTypesand getLogare already implemented at client commandsbut their description are absent at site API
命令getLogTypes和getLog已经在客户端命令中实现，但在站点 API 中没有它们的描述
Looks like it worth read source code instead of documentation
看起来值得阅读源代码而不是文档
Below jsdoc for this functions from source code :
下面来自源代码的这个函数的jsdoc：
/**
* Gets the available log types
*
* ```
* this.demoTest = function(client) {
* this.getLogTypes(function( typesArray ) {
*
* });
* };
* ```
*
* @method getLogTypes
* @param {function} [callback] Optional callback function to be called when the command finishes.
* @api commands
* @see logTypes
*/
and
和
/**
* Gets a log from selenium
*
* ```
* this.demoTest = function(client) {
* this.getLog( 'browser', function( logEntriesArray ) {
* console.log( "Log length: " + logEntriesArray.length );
* logEntriesArray.forEach( function( log ) {
* console.log( "[" + log.level + "] " + log.timestamp + " : " + log.message );
* } );
* });
* };
* ```
*
* @method getLog
* @param {string} typeString Log type to request
* @param {function} [callback] Optional callback function to be called when the command finishes.

First make sure you set loggingPrefsto { 'browser' : 'ALL' } in your nightwatch configuration otherwise you won't see entries in the browser console that were written with console.log. My nightwatch.conf.js looks something like:
首先确保在你的守夜配置中将loggingPrefs设置为 { 'browser' : 'ALL' } 否则你将不会在浏览器控制台中看到使用 console.log 编写的条目。我的 nightwatch.conf.js 看起来像：
desiredCapabilities: {
browserName: 'chrome',
handlesAlerts: true,
loggingPrefs: { 'browser': 'ALL' }
}
Next, like the others have said you just have to use the built-in getLogfunction on the client. e.g.
接下来，就像其他人所说的那样，您只需要在客户端使用内置的getLog函数即可。例如
browser.getLog('browser', function(logEntriesArray) {
console.log('Log length: ' + logEntriesArray.length);
logEntriesArray.forEach(function(log) {
console.log('[' + log.level + '] ' + log.timestamp + ' : ' + log.message);
});
});
