PTY allocation request failed on channel 0 PTY allocation request failed on channel 0 20/02/2009 Yesterday, I was trying to login to my machine and I got the following message: PTY allocation request failed on channel 0 My prompt was stuck and I could not enter commands. This happened because -for some reason- the tty related devices(/dev/ptmx, /dev/pts) were not created or mounted on my machine. In order to get this problem resolved, I created and mounted the missing devices using the following commands: 写进 rc.local 1.rm -rf /dev/ptmx 2.mknod /dev/ptmx c 5 2 3.chmod 666 /dev/ptmx 4.umount

热乎的，OKHttp Post请求参数发送流请求

阅读更多关于热乎的，OKHttp Post请求参数发送流请求

其实我从年前就开始学这个okHttp,只不过一直没成功过，遇到过400，411，500等各种错误，整的我是各种捉急呀，昨天刚开始上班，我又开始整它，还好借着我今天生日寿星最大哈，终于搞出来了，各种泪流满面呀。好了，说这么多也烦了，开始说说代码吧，这里代码我服务端用的是C# WCF，贴一个声明方法如下。 [OperationContract] [WebInvoke( Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest, UriTemplate = "GetUsers")] int GetUsers(string userName, string userPwd, String devicecid); 大家可看到这里我的Request和Response用的都是Json，所以这就要求客户端发送的必须是Json请求。好了，那么，这时候就该OkHttp上场了。先贴下，手机端点击触发事件的方法 private Object[] parameterValue; private String[] parameter; private String method;

request&response

阅读更多关于 request&response

基本概念: 在调用service之前，服务器（tomcat）会将用户的请求封装到request对象里面，同时也会创建一个response对象，通过service方法传递到我们的Servlet中。我们做一定的处理，将处理的结果，封装到response中，再将response对象返回给服务器，服务器响应到客户端。 response: ‍ ‍ 1.设置响应体 ‍ ‍ ‍ (1) 向客户端响应文本 ‍ PrintWriter response.getWriter(); writer.write("文本") --- 向response的缓冲区中去写注: 向客户端回写中文数据时乱码乱码的原因：response缓冲区的编码方式是iso8859-1（西欧编码方式）解决方式：response.setContentType("text/html;charset=UTF-8"); 上面的代码完成两个设置：(1) 设置response缓冲区的编码---response.setCharacterEncoding("UTF-8"); (2) 设置浏览器的解码方式----response.setHeader("Content-Type", "text/html;charset=UTF-8") ‍ (2) 向客户端响应字节 ‍ ServletOutputStream out = response

阅读更多关于 How to stop NodeJS “Request” module changes request when using proxy

问题 Sorry if this comes off as confusing. I have written a script using the NodeJS request module that runs and performs a function on a website then returns with the data. This script works perfectly fine when I do not use a proxy by setting it to false. This is not a task that is NOT allowed to be done with Selenium/puppeteer proxy: false However, when I set a (working) proxy. It fails to perform the same task and is detected by the website firewall/antibot software. proxy: http://xx.xxx.xx.xx
