Jmeter上传附件EXCEL

1.通过对上传附件接口进行抓包，获取的信息如下：

2.在jmeter脚本中添加http请求，并添加http请求头信息如下：

3.在http请求中添加上传附件的内容如下，由于我上传的是excel,所以MIME类型中输入：application/vnd.ms-excel：

4.保存脚本后，运行脚本，添加擦看结果树，观察响应结果，如下：

解决方案如下：

jmeter上传附件失败，正确添加了头信息和body信息后，仍然上传失败，后来发现是HTTP信息头管理器中，设置的Content-Type：application/json，

而上传附件请求中Content-Type:multipart/form-data,JMeter在写API的case时,经常会用到全局性header manager，因此会覆盖 上传附件请求中的Content-Type，

导致附件上传失败。

解决的方法是：在上传附件的请求中添加BeanShell PreProcessor，在BeanShell PreProcessor中添加下面的代码：

sampler.getHeaderManager().removeHeaderNamed("Content-Type");

如果接下来的case还想再加回content-type=application/json, BeanShell里面代码:

import org.apache.jmeter.protocol.http.control.Header;
     sampler.getHeaderManager().add(new Header("Content-Type","application/json"));
