ipa包重签名

Posted on by — No Comments ↓

如果ipa打包时，签名文件不包括你的设备id，用itunes安装后是无法使用的，
这样，就要重新申请包含你设备id的证书，用下面的方法重签名：

1、把ipa和新证书放到同一目录下

2、新建文件resignipa.sh

IPA="xx.ipa"
IPAOUT="xxx.ipa"
PROVISION="xxxx.mobileprovision"
CERTIFICATE="xxxxx" # must be in keychain

# unzip the ipa
unzip -q "$IPA"

# remove the signature
rm -rf Payload/*.app/_CodeSignature Payload/*.app/CodeResources

# replace the provision
cp "$PROVISION" Payload/*.app/embedded.mobileprovision

# sign with the new certificate
/usr/bin/codesign -f -s "$CERTIFICATE" --resource-rules Payload/*.app/ResourceRules.plist Payload/*.app

# zip it back up
zip -qr "$IPAOUT" Payload

3、启动命令行

chmod 777 resignipa.sh
./resignipa.sh

生成IPA包

生成ipa包有以下几种方式：
1、自己手工打包
a、找到xcode生成app包
b、新建文件夹Payload，并把app包放进去
c、（可选）准备一张jpeg格式的图（<500*500px），用来显示在iTunes中 d、（可选）命名这张图为iTunesArtwork（无扩展名），并把它放在和Payload同一级目录中 e、将Payload和iTunesArtwork压缩，后缀名改为ipa即可 2、利用itunes a、找到xcode生成app包 b、直接拖到itunes中 c、在itunes的app目录下找到对应ipa即可（无图片） 3、利用xcode a、生成Archive b、在organizer的Archive界面选择share

go语言channel测试，请注意空格

package main
import "fmt"

const num_go_routine = 10000

func channeltest(left,right chan int){
	left<-1+<-right;
}

func main(){
	leftmost := make(chan int);

	var left,right chan int = nil,leftmost;
	for i:=0; i<num_go_routine; i++ {
		left, right = right, make(chan int);
		go channeltest(left,right);
	}

	right<-0;
	x := <-leftmost;
	fmt.Println(x);
}

Java Https Soap Server(Tomcat-Axis2)

Posted on by — No Comments ↓

1、%Tomcat%/server/server.xml
找到下面一段：

<!--
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" />
-->

替换为：

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true"  
	    maxThreads="150" scheme="https"  secure="true"
	    clientAuth="false" sslProtocol="TLS"
	    disableUploadTimeout="true" enableLookups="false"
	    keystoreFile="D:/JavaContainer/apache-tomcat-6.0.35-x86/myKeyStore.jks"
	    keystorePass="sslTestPwd"
/>

这样，就可以用https://127.0.0.1:8443访问Tomcat了。

2、在需要使用https项目的axis2.xml文件中，增加下面内容

        <!--修改-->
	<transportReceiver name="http"
		class="org.apache.axis2.transport.http.AxisServletListener">
		<parameter name="port">8080</parameter>
	</transportReceiver>
        <!--新增-->
	<transportReceiver name="https"
		class="org.apache.axis2.transport.http.AxisServletListener">
		<parameter name="port">8443</parameter>
	</transportReceiver>

这样，该WebService就可以使用https进行访问了：）

C# Https Soap Server(IIS7)

Posted on by — No Comments ↓

1、首先准备一个p12格式的服务端证书
无论是购买，还是用openssl或java keytool生成自签名证书都可以

2、在IIS7的根目录，选中“安全性->根目录证书”，选择“导入”即可

3、如果显示证书链有问题，则在IE中导入CA证书就好了

4、在需要HTTPS的网站上，选择“绑定”，绑定类型为https，选择需要的证书

5、在客户端的IE中，导入CA证书就好了
