在jmeter中我需要发送一个带有随机文件名的文件路径，如何获取该随机文件名以传递请求

标签： web-services jmeter performance-testing load-testing webrequest

我正在加载测试Web应用程序场景，其中包括：

1。）首先，我需要上传一个将被解析的excel文件，并将表格（excel中的标签）加载到下拉列表中。

2.）然后在下拉列表中选择一个选项并单击导入按钮。

3。）点击导入后，弹出一个新的弹出窗口，其中包含一些加载到网格中的数据＆＃34;更新到数据库＆＃34;按钮。现在单击“更新到数据库”按钮。

这是我的负载测试场景，我需要加载测试＆＃34; import＆＃34;和＆＃34;更新到数据库＆＃34;请求

在这种情况下，4个请求有效。

  • 第1点：servicename网址为：/xxx/xxx/uploadLoader.aspx
参数中的

： 2个视图状态，按钮，appuser，公司，文件名（包含多部分数据）

响应：它返回文件上传控件的HTML

  • 第2点使用2个请求：

a）服务网址为：/xxxx/xxxx.asmx/updateImportSubTableFormat

in params： 

{"as_connstring":["GET"],"alist_import":[{"__type":"ApplecartDS.DataLib.ImportTableMain","rowstate":"OLD","tableno":"019","oldtableno":"019","formatid":"I0000012","oldformatid":"I0000012","columnname":"pay_billrefno","oldcolumnname":"","columndesc":"Bill No","aormdesc":"Actual","excelcolumnname":"D","excelcolumnno":"3","excelcolumnnameadd1":"","excelcolumnnoadd1":-1,"excelcolumnnameadd2":"","excelcolumnnoadd2":-1,"serialno":"1","oldserialno":2,"formatname":"","startingrowno":0,"endingrowno":0,"keycolumn":"","keycolumndesc":"","payiddesc":null,"attributetype":"","paytype":"A",".............**some more output data here**.................... 1,"excelcolumnnameadd2":"","excelcolumnnoadd2":-1,"serialno":"3","oldserialno":3,"formatname":"","startingrowno":0,"endingrowno":0,"keycolumn":"","keycolumndesc":"","payiddesc":null,"attributetype":"","paytype":"A",""provision_actual":"P","dsexecstatus":"","dsmsg":"","slno":0,"as_fromatid":"I0000012","ai_xlcolumnname":"A","ai_xlcolumnno":"1","ai_startrow":"2","ai_endrow":0,"ai_header":"1","as_payid":"MEDRE","as_leaveid":"MEDRE","as_wfdcolname":"","ai_wfdcolno":0,"as_arrcolname":"","ai_arrcolno":0,"as_transafertype":"A"}

响应： 

{"d":[{"__type":"ApplecartDS.DataLib.ImportTableMain","rowstate":"OLD","tableno":"","oldtableno":"","formatid":"","oldformatid":"","columnname":"","oldcolumnname":"","columndesc":"","aormdesc":"","excelcolumnname":"","excelcolumnno":0,"excelcolumnnameadd1":"","excelcolumnnoadd1":-1,"excelcolumnnameadd2":"","excelcolumnnoadd2":-1,"serialno":0,"oldserialno":0,"formatname":"","startingrowno":0,"endingrowno":0,.............**some more output data here**...................."","valuefrom":"E","default_value":"","aorm":"A","benefitsid":"","licpayid":"","createmaster":"","allowzero":"N","groupid":"","groupdesc":"","reimbpayid":"","provision_actual":"P","dsexecstatus":"","dsmsg":"","slno":0}]}

注意：如果我在parmas中遇到相同的请求，那么它会返回正确的相同响应。

b）服务网址为：/AAA/AAA.asmx/importXLData

in params： 

{"as_connstring":["GET"],"as_filename":"C:\\Websites\\xxxx\\xxxx\\admin\\001\\admin115.248.100.6825520164659134Import_Template.xlsx","ai_header":2,"as_tablename":"rm_claimsmain","as_sheetname":"'Reim claim$'","as_tableno":"019","as_fromatid":"I0000012","as_creditperiodid":"","isUpdate":false,"isupdatemonattribute":false,"alistUpdatedata":[],"as_excelfilepath":"C:\\Websites\\xxxx\\xxxx\\admin\\001\\admin115.248.100.6825520164659134Import_Template.xlsx"}

响应 

{"d":[{"__type":"ApplecartDS.DataLib.ExcelDataImport","CValues1":"","CValues2":"","CValues3":"","CValues4":"","CValues5":"","CValues6":"","CValues7":"","CValues8":"",..........**very long out put data here**.......
,"NValues50":0,"NValues51":0,3":0,"IValues4":0,"rowmodify":"N","rowstate":"OLD","dsexecstatus":null,"dsmsg":""}]}

注意：但是，如果我再次点击相同的请求，则会显示与上面的响应不同的响应（第一次响应）。因为在手册的情况下文件名每次都会更改，但我无法在JMeter请求中获取新文件名以传递它。

第二次回复： 

{"d":[{"__type":"ApplecartDS.DataLib.ExcelDataImport","CValues1":"","CValues2":"","CValues3":"","CValues4":"","CValues5":"","CVal","CValues17":"","CValues18":"","CValues19":................................. dsexecstatus":"FAIL","dsmsg":"Exception : System.Data.OleDb.OleDbException (0x80004005): The Microsoft Office Access database engine could not find the object \u0027C:\\xxxx\\xxxx\\xxx\\admin\\001\\admin115.248.100.6825520165121629Import_Template_test_case_9May2016.xlsx\u0027.  Make sure the object exists and that you spell its name and the path name correctly.

第3点正在使用1个请求

服务网址：/xxxx/xxxx.asmx/importXLData

in params 

{"as_connstring":["GET"],"as_filename":"C:\\xxxx\\xxxx\\temp\\admin\\001\\admin115.248.100.682552016571324rm_claimsmain.xml;C:\\Websites\\cPayv8html\\temp\\admin\\001\\admin115.248.100.682552016571324rm_cliams.xml","ai_header":"1","as_tablename":"rm_claimsmain","as_sheetname":"'Reim claim$'","as_tableno":"019","as_fromatid":"I0000012","as_creditperiodid":"","isUpdate":true,"isupdatemonattribute":false,"alistUpdatedata":[{"__type":"ApplecartDS.DataLib.ExcelDataImport","CValues1":"Employee No;C;30;em_empno","CValues2":"Bill No;C;30;","CValues3":"Bill Date;D;30;","CVal/Date(-62135596800000)\/"..........**some more in data**..........,"DValues10":"\/Date(-62135596800000)\/","ls_msg1":"5","ls_msg2":"C:\\xxxx\\xxxx\\xx\\admin\\001\\admin115.248.100.682552016571324rm_claimsmain.xml;C:\\xxxx\\xxx\\xx\\admin\\001\\admin115.248.100.682552016571324rm_cliams.xml","ls_msg3":"","ls_msg4":"","NValues1":0,"NV4":0,"rowmodify":"N","rowstate":"OLD","dsexecstatus":null,"dsmsg":""}],"as_excelfilepath":"C:\\xxxx\\xxxx\\xxx\\admin\\001\\admin115.248.100.6825520164659134Import_Template_test_case_9May2016.xlsx"}

响应 

{"d":[{"__type":"ApplecartDS.DataLib.ExcelDataImport","CValues1":"","CValues2":"","CValues3":"","CValues4":"","CValues5":"","CValues6":"","CValues7":"","CValues8":"","CValues9":"","CValues10":"","CValues11":"","CValues12":"","CValues13":"","CValues14":"","CValues15":"","CValues16":"","CValues17":"","CValues18":"","................................ "rowmodify":"N","rowstate":"OLD","dsexecstatus":"SUCCESS","dsmsg":"Update to Database success !    New Rows added :0 \u003c\u003e Rows Updated : 49"}]}

如果我再次点击相同的请求，则第二次响应是：

......................"dsexecstatus":"FAIL","dsmsg":"Exception : Could not find file \u0027C:\\Websites\\cPayv8html\\temp\\admin\\001\\admin115.248.100.682552016525264rm_claimsmain.xml\u0027."}]}

我的问题是在第二次响应时它没有显示正确的响应，因为文件名随机变化，我无法跟踪它以将更改的文件路径传递给请求。

有没有办法处理它？请帮帮我，如何用真实的响应加载测试。

$ {__ RandomString（6，a12zeczclk，MYVAR）} 将返回从a12zeczclk集中挑选的6个字符的随机字符串并将结果存储在MYVAR中，MYVAR将包含类似2z22ak或z11kce的字符串，......

当您上传文件时，它似乎存储在临时位置的某个位置，当文件导入数据库时​​ - 它被删除。所以这是经典的“关联”示例，您需要从先前的响应中获取动态参数并将其添加到下一个请求中。

我建议仔细检查服务器响应并从那里获取临时文件名。

当您的服务器使用JSON响应时，我建议使用

JSON Path语法非常简单，请查看以下参考：
