目的：用jmeter测试MultipartFile上传多个文件

今天用jmeter测试上传文件的时候遇到点问题，以此博客作为记录，同时也让大家少走弯路。

1.加入文件上传的jar包

<dependency>
    		    <groupId>commons-fileupload</groupId>
    		    <artifactId>commons-fileupload</artifactId>
    		    <version>1.3.1</version>
    		</dependency>

2.在spring-mvc.xml中配置MultipartResolver处理器

<bean id="multipartResolver"
    		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    		<property name="defaultEncoding" value="UTF-8" />
    		
    		<property name="maxUploadSize" value="10240000" />
    	</bean>

3.jmeter配置如下， use multipart/form-data for post打勾，同时MIME类型设置为multipart/form-data，参数名称必须和controller中的名字一致，另外不需要再画蛇添足添加信息头的设置

4.controller如下

public Result getPics(HttpServletRequest request,@RequestParam(value = "file", required = false)MultipartFile[] file) {
    		System.out.println("进来了————————————————");
    		Result<String> result = new Result<String>();
    		// 身份证识别url
            String idcardIdentificate = "https://aip.baidubce.com/rest/2.0/ocr/v1/idcard";
            System.out.println("长度："+file.length);
    		if(file!=null&&file.length==2){  
                //循环获取file数组中得文件  
              for(int i = 0;i<file.length;i++){
                  MultipartFile files = file[i];  
                  byte[] imgData;
    			try {
    				imgData = files.getBytes();
    				String imgStr = Base64Util.encode(imgData);
    				System.out.println("base64St:"+imgStr);
    				//身份证正面
    				if(i==0) {
    					String params = "id_card_side=front&" + URLEncoder.encode("image", "UTF-8") + "="
    		                    + URLEncoder.encode(imgStr, "UTF-8");
    					String accessToken = "#####调用鉴权接口获取的token#####";
    					JSONObject idcardResp= JSONObject.parseObject(HttpUtil.post(idcardIdentificate, accessToken, params));
    					String status = idcardResp.get("image_status").toString();
    					String cardType=idcardResp.get("risk_type").toString();
    					//身份证读取不正常
    					if(!"normal".equals(status)||!"risk_type".equals(cardType)) {
    						result.setError(status,BaiduErrorConstant.errorMap.get(status));
    						result.setData(idcardResp.toString());
    						return result;
    					}
    				}
    				//身份证背面
    				else {
    					String params = "id_card_side=back&" + URLEncoder.encode("image", "UTF-8") + "="
    		                    + URLEncoder.encode(imgStr, "UTF-8");
    				}
    			} 
    			 catch (Exception e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
              }
    		}
    		return null;
    	}
