如何在非GUI模式下使用Java代碼進行JMeter測試的post請求中添加請求體數據？

Question

這是一個 Java 代碼形式的 Jmeter POST 請求。 我運行此代碼沒有錯誤，但我也沒有得到響應，因為我處理請求正文數據的方法似乎是錯誤的。

我已經使用此代碼來配置 jmeter POST 請求並添加正文數據，但是當我檢查響應時，請求正文似乎為null 。

也許您應該向httpSampler添加參數，而不是向sampler添加參數，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 從 Java 代碼構建 JMeter 測試，請查看在不使用 JMeter GUI和jmeter-from-code存儲庫的情況下啟動 JMeter 測試的五種方法，了解一些可以重復使用的代碼片段。
