jmeter beanshell取csv多行数据

你可以使用以下Beanshell代码来取CSV文件的多行数据：

import java.io.BufferedReader;
import java.io.FileReader;

String fileName = "path/to/your/csv/file.csv";
int lineNumber = 1; // start from line 1
int numberOfLines = 3; // get 3 lines of data

// create a StringBuilder to store the lines of data
StringBuilder data = new StringBuilder();

// read the file and get the specified lines of data
try (BufferedReader br = new BufferedReader(new FileReader(fileName))) {
    String line;
    while ((line = br.readLine()) != null && lineNumber <= numberOfLines) {
        data.append(line).append("\n");
        lineNumber++;
    }
} catch (Exception e) {
    log.error("Error reading file: " + fileName);
}

// print the lines of data
log.info("Data from lines " + (lineNumber - numberOfLines) + "-" + (lineNumber - 1) + ": " + data.toString());

这段代码会从CSV文件中读取指定行数的数据，并将其存储在StringBuilder中。你可以根据需要修改行数和文件路径。记得在JMeter中引用外部库文件，以便在测试中使用Beanshell脚本。
