JMeter groovy预处理器在尝试配置“自定义SOAP采样器”时抛出异常

我试图为创建基于groovy的预处理器**自定义SOAP采样器*插件，旨在涵盖以下任务：JMeter groovy预处理器在尝试配置“自定义SOAP采样器”时抛出异常

从csv输入文件读取文件附件列表;
空当前与自定义SOAP采样注册的附件列表;
注册从csv文件读取的附件与自定义SOAP采样器。

经过对网络的一些相当广泛的研究 - 我对整个groovy，java，jmeter topic--是全新的，我设法组装了如下所示的groovy脚本。

// read data from csv input file 
ArrayList recLst = new ArrayList(); 
String fldsep = vars.get("fldsep"); 
String fldhd = vars.get("fldhd"); 

Integer i = 0; // TODO: test/debugging only 
new File(vars.get("indat")).eachLine('UTF-8') { 
    if ((it != null) && (fldhd != null) && (!it.trim().equals(fldhd.trim())) && (i < 2)) { 
     recLst.add(it.trim()); 
    } // if 
    i++; // TODO: test/debugging only 
} // File.eachLine 

// TODO: test/debugging only 
for (rec in recLst) { 
    String[] flds = rec.split(fldsep); 
    vars.put("DBGtmstmp", flds[0]); 
    vars.put("DBGprodid", flds[1]); 
    vars.put("DBGtenid", flds[2]); 
    vars.put("DBGfnam", flds[3]); 
} 

ArrayList oldAtts = new ArrayList(); 
oldAtts = ctx.getCurrentSampler().getAttachments(); 
vars.put("DBGoldatts", oldAtts.size()); 
// TODO: test/debugging only 

// extract relevant parts and feed into Custom SOAP Sampler (registered attachments) 
// csv format: TMSTMP;PRODID;TENID;FNAM;MDAT 
if (recLst.size() > 0) { 
    // empty current attachment list 
// ArrayList oldAtts = ctx.getCurrentSampler().getAttachments(); 
// vars.put("DBGoldatts", oldAtts.size()); // TODO: test/debugging only 

    if (oldAtts.size() > 0) { 
     for (attDef in oldAtts) { 
      attDef.attachment = null; 
      attDef.contentID = null; 
      attDef.contentType = null; 
      attDef.type = null; 
     } // for 
    } // if 

    // create new attachment list 
    ArrayList newAtts = new ArrayList(); 

    for (rec in recLst) { 
     String[] flds = rec.split(fldsep); 

     def attDef = ctx.getCurrentSampler().getAttachmentDefinition(); 
     attDef.attachment = new File(flds[3]); 
     attDef.contentID = "flds[0]"; 
     attDef.contentType = "application/pdf"; // one of selections from the dropdown (no PDF listed there) 
     attDef.type = 1;      // 1 = resource, 2 = variable 

     newAtts.add(attDef); 
    } // for 

    if (newAtts.size() > 0) { 
     ctx.getCurrentSampler().setAttachments(newAtts); 
    } // if 
} // if

不幸的是这似乎是失败的，所以我加了一些调试信息，例如。设置变量（'DBG ....'）。尝试检索当前定义的附件并将“DBGoldatts”设置为找到的附件数量时，“DBGtmstmp”，“DBGprodid”，“DBGtenid”和“DBGfnam”正在按预期设置，引发异常。

设置断点在我的Groovy脚本（JSR223PreProcessor），并启动调试器（BlazeMeter）产生

继续测试计划执行（步过）产生

，并完成执行结果在

我不得不承认，我完全在如何解决这个问题。

我的设置包括：

Ubuntu Linux操作系统17.04;
Apache JMeter 3.1 r1770033;
BlazeMeter Step-by-step Debugger 0.3;
自定义SOAP采样器1.3;
Groovy 2.4.7（脚本引擎2.0）。

样品输入csv文件

TMSTMP;PRODID;TENID;FNAM;MDAT 
'20170406112044044970077';'PROD01';'TENANT03';'/media/sf_Projects/tstprj/archive/tstdoc/tstdoc-00000.pdf';'<?xml version=1.0 encoding=UTF-8?><tstpfx:metainformation xmlns:tstpfx=http://my.host.local/tstprj/metainformation_v2.xsd id=000000069496>meta data #01</tstpfx:metainformation>

'

此文件得到读两次：（1）由JSR223预处理器建立附件列表; （2）由自定义SOAP采样，随后在该文件中的每个条目进行迭代，并通过相关的位&羁绊的SOAP信封

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tstprj="http://my.host.local/"> 
    <soapenv:Header/> 
    <soapenv:Body>

请参阅api，对于Sample Interface没有这样的方法。 https://jmeter.apache.org/api/index.html?org/apache/jmeter/samplers/Sampler.html – Rao

@Rao在查看相应的[Custom SOAP Sampler的] GitHub wiki页面（https： //github.com/spinning10/JMeterSoapSampler/wiki），在这个例子中提到了这个特定的采样器调用。我还在其他网站（[IT质量]（http://driven-by-tests.blogspot.co.at/2016/02/jmeter-custom-soap-sampler.html））中找到了此示例。 – user4338

你应该在报告问题：

https://github.com/Blazemeter/jmeter-debugger

插件包取样到自定义SamplerDebug。

所以，你的代码：

ctx.getCurrentSampler()

返回，而不是在这个文档中提到的类SamplerDebug：

JMeterSoapSampler
