小编Bla*_*rai的帖子

我试图弄清楚a URI.escape和URI.encodeRuby 之间的区别.

也没有做我想要的,即完全编码URL.

例如,我想http://my.web.com成为http%3A%2F%2Fmy%2Eweb%2Ecom

我需要对变量进行编码Jmeter,但它不是参数.例如:

URL path: /folder/guest/id;token=${token}/profile?details=yes

我想编码${token}变量,只编码令牌变量.我知道您可以encode在参数部分中进行选择,但这不是参数.

有谁知道如何做到这一点？

我对PowerShell Start-Job和Start-ProcessPowerShell 之间的区别感到有些困惑.我知道这Start-Job将在后台运行,但我想知道事情是否与Start-Job使用不同,Start-Process以及是否存在使用一个而不是另一个的其他含义.什么时候应该使用另一个,哪个有优势？

最近,Android添加了使用API​​ 18(JellyBean 4.3)连接到EAP WIFI的功能.我已经找了很多例子,但找不到任何例子,我也无法连接我的代码.一切似乎按预期工作,但实际连接似乎不起作用.

这是我正在做的事情:

Log.d( "WiFi", "adding network via Android Enterprise Config with SSID: " + ssid );
                    WifiEnterpriseConfig enterpriseConfig = new WifiEnterpriseConfig(); 
                    wifiConfig = new WifiConfiguration();
                    wifiConfig.SSID = ssid; 

                    enterpriseConfig.setIdentity(userName);
                    enterpriseConfig.setPassword(passWord);
                    enterpriseConfig.setEapMethod(WifiEnterpriseConfig.Eap.PEAP); 
                    wifiConfig.enterpriseConfig = enterpriseConfig;
                    Log.i("WIFI", "My wifi"+ wifiConfig.status); 
                    networkId = wfm.addNetwork(wifiConfig);

                    wfm.enableNetwork(networkId, true); // this initiates the connection

无论出于何种原因,都没有建立联系.似乎其他一切都设置正确.如果我遗漏了任何东西,请告诉我,我很乐意添加它.

任何帮助或方向将不胜感激.

这是什么意思:

{@link KeyEvent#KEYCODE_ENTER}

我已经看过几次了,我不太清楚它代表什么.我正在使用Robotium,JUnit和Android编写测试程序.如果有人可以就这个问题提供一些澄清,更具体地说,{@link}部分,这将是伟大的!

先感谢您.

我是新来的Objective-C,我有麻烦了整个nonatomic,strong,weak等我想知道如果我将不得不使用的任何问题Core Data与float它们像这样定义的值:

@property (nonatomic) float * rating;
@property (nonatomic) float * mRating;

我应该以不同的方式宣布吗？

迁移到Swift 3后,当我尝试执行以下操作时出错:

self.publicDB.save(listRecord, completionHandler: { (record, error) -> Void in
        if let saveError = error {
            NSLog("There was an error saving the record: %@", saveError)
        }...

有人可以告诉我为什么这是我可以做的相对容易产生输出？

错误是NSLog unavailable: variadic function unavailable.

我曾经Rails scaffolding使用终端的命令制作模型:

rails generate scaffold Venue venueid:string, venueName:string, venueAddress:string, venueCity:string, venueState:string, venueZip:integer, venuePhone:string, venueAge:int

一切似乎安装或生成好,但当我运行时,rake db:migrate我得到以下错误:

rake aborted!

是否有一种简单的方法可以将Epoch时间转换为使用Ruby的标准格式？如果可以,我可以自定义它的显示方式吗？

使用Ruby从文件夹中获取所有文件的名称

我是新手Ruby,我正在尝试从特定目录中获取所有文件名.只有一个级别,只需要获取整个名称列表.我怎么做？我已经看了一些关于这个主题的其他帖子,但都没有帮助.
