小编joh*_*ohn的帖子

我正在使用Tomee.logs文件夹包含这样的文件

1. localhost_access_log.2016-12-02.txt
2. localhost.2016-12-02.log
3. catalina.2016-12-02.log
4. 主机manager.2016-12-02.log
5. manager.2016-12-02.log

我在文档中寻找解释,但可以找到任何东西.据我所知,这些localhost文件只记录"主机"活动.这对吗？这些文件有什么区别？他们会记录不同类型的消息吗？

我在Windows 10上安装了最新的Node and Angular

npm install npm@latest -g 
npm install -g @angular/cli@latest 

但是，当我尝试启动一个项目时ng new new-project，出现以下错误

    npm WARN tarball tarball data for @angular/compiler@^6.1.0 (sha512-TY6axB1c7VvYXf+ebFDq3Ej+edgii3CDxew8HnyTFAWeDF2Gh8io1vTYwtdyDka6U53ASaheM1HpiUjzvYH0jQ==) seems to be corrupted. Trying one more time. 
    npm WARN tar ENOENT: no such file or directory, open 'C:\Users\admin\Desktop\...\node_modules\.staging\@angular\common-6be83a81\locales\si.js'
    ...

    npm ERR! A complete log of this run can be found in:

    Package install failed, see above.

我尝试完全卸载Node.js和Angular CLI，然后再次重新安装

 npm install npm@latest -g 
 npm install -g @angular/cli@latest 

但是还是一样的错误.....所以我用谷歌搜索了这个问题。似乎有些人也有，但是对于某些人来说，它却神奇地消失了。

如何解决这个问题？

我的测试页面包含一个onclick进行ajax调用的链接,如下所示

 <a title="test delim" alt="" 
onclick="$find('MetricsReport').exportData('TAB');"
 href="javascript:void(0)" 
style="color: rgb(50, 50, 50); . . . ">Click to download</a> 

单击上面的链接后,报告将下载到默认下载位置.

我正在用java selenium测试它

 ((JavascriptExecutor) driver).executeScript("$find('MetricsReport').exportData('TAB');"); 

它工作正常ChromeDriver,但不起作用PhantomJSDriver.不会抛出任何错误.它有点执行但没有任何反应.该报告未下载

我怎样才能使用它PhantomJSDriver？

我需要每天早上9点打印所有收到的电子邮件.这是我试过的

电子邮件部分工作正常.我能够连接到电子邮件并打印所有.当我介绍Alarm Manager时会出现问题.当我运行它时,没有任何反应.它只是挂起

如何为r中的变量分配一个非常长的字符串？

以下工作正常

testVar <- "test;test;"  

但是以下+在RStudio控制台中给出了一个奇怪的结果.

testVar <- "test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test

当我按下Esc按钮并打印时testVar,它只打印test;test;

我不断从 Checkmarx 代码扫描仪收到这个烦人的错误，

Method getTotalValue at line 220 of src\java\com\example\PeopleController.java 
gets user input for the personName element. This element’s value then flows through
the code without being properly sanitized or validated and is eventually 
displayed to the user. This may enable a Cross-Site-Scripting attack. 

这是我的代码。我想我做了所有必要的验证。还有什么？？？

@Slf4j
@Configuration
@RestController
@Validated

    @Autowired
    private PeopleRepository peopleRepository; 

    @RequestMapping(value = "/api/getTotalValue/{personName}", method = RequestMethod.GET)
    @ResponseBody
    public Integer getTotalValue(@Size(max = 20, min = 1, message = "person is not found") 
    @PathVariable(value="personName", required=true) …

我这里有一个简单的例子.这是一个带有js和css文件的"all in one"html.

我正在使用DataTables响应主题.

以下是问题复制步骤:

1)将以下代码保存到html文件中

2)在Chrome浏览器中打开此文件

3)减小浏览器的大小,使第四个字段不可见

4)单击绿色的"+"扩展按钮

5)选择任何值

6)单击绿色的"+"按钮以折叠

7)再次单击绿色的"+"按钮展开

8)实际上并未选择您选择的值

为什么？？？

以下是两个选项

1)创建一个Callable并多次提交

Callable<String> callable = new MyCallable();
        for(int i=0; i< 100; i++){
           Future<String> future = executor.submit(callable);
            list.add(future);
        } 

2)为每个线程创建多个Callables

 for(int i=0; i< 100; i++){
        Future<String> future = executor.submit(new MyCallable());
        list.add(future);
    } 

什么是最佳做法？

我正在尝试使用jdbc连接到hive.我一直收到这个错误.我尝试查找它但不能隐藏任何有用的东西.

这是我的连接字符串: jdbc:hive2://hostname.xxx.com:10000/default;principal=hive/hostname.xxx.com@HADOOP_ENV.COM

这是什么错误: java.lang.NoSuchMethodError: org.apache.hadoop.security.authentication.util.KerberosUtil.hasKerberosTicket(Ljavax/security/auth/Subject;)Z

我使用这个 power shell 脚本从 Git Hub 存储库下载文件

$url = "https://gist.github.com/ . . ./test.jpg"
$output = "C:\Users\admin\Desktop\test.jpg"
$start_time = Get-Date

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $output)
#OR
(New-Object System.Net.WebClient).DownloadFile($url, $output)

Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)" 

它适用于一个文件。如何使用 PowerShell 下载完整的存储库？我无法使用git pull.

编辑 这是我在真实存储库上尝试的内容。
