标题: vars.put 赋值失败,在调用beanshell preprocessor相关api之后


我的测试需要根据当前http请求参数计算sha1签名,用到了beanshell preprocessorfollowing is beanshell preprocessor source code

1. import java.util.Date;
   
2. 
   
3. import java.util.HashMap;
   
4. import java.util.Iterator;
   
5. import java.util.Map;
   
6. import java.util.Collection;
   
7. 
   
8. import org.apache.jmeter.config.Arguments;
   
9. import org.apache.jmeter.testelement.property.CollectionProperty;
   
10. 
    
11. import org.apache.commons.codec.digest.DigestUtils;
    
12. 
    
13. 
    
14. Date date = new Date();
    
15. long time = (date.getTime());
    
16. 
    
17. String s = String.valueOf(time);
    
18. 
    
19. vars.put("timestamp1",s);
    
20. 
    
21. 
    
22. 
    
23. 
    
24. Arguments args = sampler.getArguments();
    
25. log.info(String.valueOf(args.getArgumentCount()));
    
26. Map reqMap = args.getArgumentsAsMap();
    
27. 
    
28. reqMap.put("sign_key","123");
    
29. reqMap.put("client_id","456");
    
30. 
    
31. ArrayList arrlist=new ArrayList();
    
32. 
    
33. for(String key:reqMap.keySet()){
    
34.     log.info( "key: "+ key + " and value: "+ reqMap.get(key));
    
35.     if(key.equals("sign") || key.equals("access_token"))
    
36.     {
    
37.                 continue;
    
38.     }
    
39.     arrlist.add(key);
    
40. }
    
41. 
    
42. Collections.sort(arrlist);
    
43. String sign="";
    
44. for(int i=0;i<arrlist.size();i++)
    
45. {
    
46.     String key=(String)arrlist.get(i);
    
47.     sign+=key;
    
48.     sign+=(String)reqMap.get(key);
    
49. }
    
50. 
    
51. log.info(sign);
    
52. 
    
53. String final_sign=DigestUtils.sha1Hex(sign);
    
54. 
    
55. 
    
56. log.info(final_sign);
    
57. vars.put("sign1",final_sign);

复制代码

在jmeter GET请求 form中有一个变量 'sign', with value of ${sign1}, 我的意图是用最后的代码把var.put("sign1" , final_sign),把计算好的final_sign,赋值给form里面的那个变量的值.
但是,有问题,我发现,每次调用jemter 相关的api,最后的"vars.put("sign1",final_sign)" 会失效导致最后出去的http请求还是 http....sign={sign1}... 没有被替换掉
