JAVA球衣org.apache.commons.fileupload.FileUploadException由于未找到多部分边界，因此请求被拒绝

Question

我只有发帖网址，不确定发帖请求的实现方式，我试图以多部分形式发送数据的发帖请求中的文件并获取 org.apache.commons.fileupload.FileUploadException由于未找到多部分边界，请求被拒绝 我在这里做什么错了。

dataArr = ["1","3","9"];
oneArr  = ["1","2","5"];
twoArr  = ["4","9"];

 updateData(dataArr){
 for (let index = 0; index < dataArr.length; index++) {

            let orgIndx = oneArr.findIndex(dataArr[index]);
            oneArr.splice(orgIndx,1);

            let orgIndx1 = twoArr.findIndex(dataArr[index]);
            twoArr.splice(orgIndx1,1);

}
console.log("oneArr = "+oneArr);
console.log("twoArr = "+twoArr);
