JMeter - 从目录中读取文件 [英] JMeter - Read Files from Directory

问题描述

使用 Apache JMeter

Using Apache JMeter

第一个问题:我能够从目录中读取单个文件(包含所有数据)并使用其数据.

First question: I was able to read one single file (containing all the data) from a directory and use its data.

但是现在要求为每个数据点一个单独的文件，这意味着我必须将许多数据文件放在一个目录中，然后读取这些文件关闭该目录.我有一组数据文件，但我不知道如何循环读取每个文件并将其发送到 JMeter.

However now the requirement is to have a separate file for each data point, that means I will have to put many data files in a directory and then read the files off that directory. I have a set of data files, but I do not know how to read each of the files in a loop and send it to JMeter.

第二个问题:我们这里讲的数据是一个JSON msg，而且是缩进的，多行，如何将多行文件读入单输入变量?同样，当 JSON msg 是一行时，我没有问题.

Second Question: the data we are talking about here is a JSON msg, and it's indented and multi-line, how to read a multi-line file into a single input variable? Again, I had no problem when the JSON msg is a single line.

推荐答案

1. 使用 Beanshell Sampler 将文件列表转换为 JMeter 变量:

1. Use Beanshell Sampler to convert files list into a JMeter Variable:

• 将 Beanshell Sampler 添加到您的测试计划莉>

• 将以下代码放入采样器的脚本"区域:

• Add a Beanshell Sampler to your test plan

• Put the following code into the Sampler's "Script" area:

File folder = new File("/path/to/your/folder");
File[] files = folder.listFiles();
int counter = 1;
for (File file : files) {
    vars.put("file_" + counter, file.getAbsolutePath());
    counter++;
}

这将导致变量设置为:

file_1=/path/to/your/folder/file1.txtfile_2=/path/to/your/folder/file2.txt等

file_1=/path/to/your/folder/file1.txt file_2=/path/to/your/folder/file2.txt etc.

添加ForEach Controller 之后Beanshell Sampler 并配置如下:

Add ForEach Controller after Beanshell Sampler and configure it as follows:

• 输入变量前缀:file
• 循环的起始索引:0
• 循环结束索引:留空
• 输出变量名:任何有意义的，即current_file
• 勾选数字前加_"
