Jmeter secondary development to realize rsa encryption

jmeterFunctions assistant provides a large number of,像 counter、digest、random、split、strLen,These functions in the interface test、Performance testing is used in great quantities,But everyone in the practical work,A variety of test requirements of different,导致jmeterBuilt-in or extensions provide us all the function can't meet,This time we can diy,对JMeter进行二次开发.

Then I takeaesEncryption to illustrate how to realizeJMeter二次开发.

首先需要将jmeter的core、functions两个jar包导入到项目工程中.

这两个jar包在jmeter的lib\ext目录下,Integrity of the package name as shown below：

ApacheJMeter_core.jar

ApacheJMeter_functions.jar

接下来定义类,类名Rsa0706,继承抽象类AbstractFunction,

实现其中的4个方法execute()、setParameters()、getReferenceKey()、getArgumentDesc(),具体代码如下所示：

1、getReferenceKey方法实现

getReferenceKey()The name of the method is used to return a custom function,The following code defines a class member variablekey,值为字符串“__rsa”,key The value of this variable asgetReferenceKey()方法的返回值.

2,getArgumentDesc方法实现

getArgumentDesc()用来定义jmeterDescription of each parameter information,

Let's be encapsulatedjmeter的rsaEncryption function has two into the,Respectively is encrypted string（即明文）,As well as the public key encryption,如下代码所示,定义类成员变量desc,To save the description of the two into the reference information as the variable,作为getArgumentDesc()方法的返回值.

3,setParameters方法实现

setParameters()方法用于获取JMeterFunction of the parameter values,咱们rsaEncryption need two into the reference,Are clear、公钥,参数个数是2,在setParameters()Methods need to check into the maximum number of arguments、The minimum value is2,Then the parameter collectionCollectionInto the array toObject数组变量values中,And define a class member variableMAX_PARA_COUNT、MIX_PARA_COUNT、plaintextCV、publicKeyCV,Are stored the biggest variable number、The minimum number of variables、明文、公钥.

4,execute方法实现

方法execute()里定义的是JmeterThe main logic code a custom function,Let's put in hereaesThe business logic of the encryption method to realize

Then debugging good project intojar包,拷贝到jmeter的lib\ext目录下.

启动jmeter,可以在jmeterThe function of assistant interface to see,自定义的__rsa函数,如下截图所示.

例如公钥：
