我正在尝试为**自定义 SOAP 采样器*插件创建一个基于 groovy 的预处理器，该插件旨在涵盖以下任务：
- 从 CSV 输入文件中读取文件附件列表;
- 清空当前向自定义 SOAP 采样器注册的附件列表; 将从
- CSV 文件读取的附件注册到自定义 SOAP 采样器。
在对网络进行了一些相当广泛的研究之后 - 我对整个groovy，java，jmeter主题完全陌生--,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，这似乎失败了，所以我添加了一些调试信息，例如设置变量('DBG....')。"DBGtmstmp"、"DBGprodid"、"DBGtenid"和"DBGfnam"按预期设置，当尝试检索当前定义的附件并将"DBGoldatts"设置为找到的附件数时，会引发异常。
在我的时髦脚本(JSR223PreProcessor)上设置断点并启动调试器(BlazeMeter)产生

继续执行测试计划(单步跳过)会产生

并完成执行结果

我不得不承认，对于如何解决这个问题，我完全不知所措。
我的设置包括：
- Ubuntu Linux 17.04;
- Apache JMeter 3.1 r1770033;
- BlazeMeter 分步调试器 0.3;
- 自定义 SOAP 采样器 1.3;
- Groovy 2.4.7(脚本引擎 2.0)。
示例输入 csv 文件

此文件被读取两次：(1) 由JSR223 预处理器构建附件列表;(2)由自定义SOAP采样器，随后迭代此文件的每个条目，并将相关的位和bobs传递给SOAP信封
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tstprj="http://my.host.local/">

您应该在以下位置报告问题：
- https://github.com/Blazemeter/jmeter-debugger
该插件将采样器包装到自定义采样器调试中。
所以你的代码：
ctx.getCurrentSampler()
返回一个 SamplerDebug 而不是本文档中提到的类：
- JMeterSoapSampler
看：
