將參數進行URL編碼

String urlencoder =”要進行編碼的內容”
String str=URLEncoder.encode(urlencoder,"UTF-8");  //采用UTF-8編碼格式，將字符串urlencoder進行URL編碼，返回一個字符串,然后賦值給變量str

vars.put("str",str);  //將通過URL編碼后的變量值str賦值給jmeter的變量str

log.info(str);  //在jmeter的控制台中輸出變量值str

//String str=URLEncoder.Decode(urlencoder,"UTF-8");  //對字符串進行URL解碼，返回已解碼的字符串
