Question

这是一个java代码形式的Jmeter POST请求。我运行此代码以获得没有错误，但我也没有得到任何响应，因为我的请求正文数据的方法似乎是错误的。

我已使用此代码配置jmeter POST请求并添加正文数据，但在检查响应时请求正文显示为null。

也许您应该向httpSampler添加参数，而不是sampler，例如：

HTTPSamplerProxy httpSampler = new HTTPSamplerProxy();
httpSampler.setDomain(xx);
httpSampler.setPort(xx);
httpSampler.setPath("xx");
httpSampler.setMethod("xx");
httpSampler.addNonEncodedArgument("body", body, "");

如果您正在使用JMeter API从Java代码构建JMeter测试，请查看Five Ways To Launch a JMeter Test without Using the JMeter GUI和jmeter-from-code存储库以获取可以重复使用的一些代码段。

如何在非GUI模式下使用Java代码在JMeter测试的post请求中添加请求正文数据？
