ios开发推送证书配置好怎么使用

推送部分是自己的服务器做还是第三方，比如JPush 或者环信等等，如果是自己的服务器就要看是php ，还是java 或者是net 根据相应的服务器环境提供相关的PEM文件给服务器端配置使用。如果是Jpush 好像需要上传P12文件，环信好像也是P12 具体对应相应的sdk接入文档去看

程序在这句把args初始化为一个有10个元素的String数组，然后在下一句，马上把args的第一个元素转换为整型，这时args[0]肯定是null，所以报了转换错误。

客户端也是同样的问题

我给你一个类似的代码，你自己改一下就可以了，我不给你该了。希望对你有所帮助！

<----------------------服务器端------------------------------->

//实现多线程的网络连接

package cnsocket;

import javaio;

{

try {

//服务器开启一个端口

Systemoutprintln("等待连接");

ServerSocket ss= new ServerSocket(8090);

//等待连接,返回socket类型的对象

Socket s=ssaccept();

Systemoutprintln("连接成功，等待客户端输入信息！");

//得到客户端的信息

InputStreamReader isr=new InputStreamReader(sgetInputStream());

BufferedReader br=new BufferedReader(isr);

//向客户端传递信息

PrintWriter pw=new PrintWriter(sgetOutputStream(),true);

//实现从控制台输入数据

InputStreamReader isrS=new InputStreamReader(Systemin);

while(true)

{

String info=brreadLine();

if(infoequals("bye"))

{

Systemoutprintln("对话结束！");

break;
