1、响应乱码

 step1：指定请求节点下，新建后置控制器"BeanShell PostProcessor"

 step2：其脚本框中输入以下代码，保存

//获取响应代码Unicode编码的

String s2=new String(prev.getResponseData(),"UTF-8");

//---------------一下步骤为转码过程---------------

char aChar;

int len= s2.length();

StringBuffer outBuffer=new StringBuffer(len);

for(int x =0; x <len;){

aChar= s2.charAt(x++);

if(aChar=='\\'){

aChar= s2.charAt(x++);

if(aChar=='u'){

int value =0;

for(int i=0;i<4;i++){

aChar= s2.charAt(x++);

switch(aChar){

case'0':

case'1':

case'2':

case'3':

case'4':

case'5':

case'6':

case'7':

case'8':

case'9':

value=(value <<4)+aChar-'0';

break;

case'a':

case'b':

case'c':

case'd':

case'e':

case'f':

value=(value <<4)+10+aChar-'a';

break;

case'A':

case'B':

case'C':

case'D':

case'E':

case'F':

value=(value <<4)+10+aChar-'A';

break;

default:

throw new IllegalArgumentException(

"Malformed \\uxxxx encoding.");}}

outBuffer.append((char) value);}else{

if(aChar=='t')

aChar='\t';

else if(aChar=='r')

aChar='\r';

else if(aChar=='n')

aChar='\n';

else if(aChar=='f')

aChar='\f';

outBuffer.append(aChar);}}else

outBuffer.append(aChar);}

//-----------------以上内容为转码过程---------------------------

//将转成中文的响应结果在查看结果树中显示

prev.setResponseData(outBuffer.toString());
