关于enctype问题, multipart/form-data

the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is null,添加完信息之后到列表页,等一会就报这个错,求大神解答!enctype="multipart/form-data"这句已经在form里加上了

已采纳

现在的问题是,我debug之后,第一次都得到值了,而且也增加成功了,但是他还会再加载增加一次,这时候就全没有值了,重点是为什么要再加戴增加一次呢

ENCTYPE="multipart/form-data",这句话的意思是把你表单的所有信息以流方式提交,页面上的所有信息已经都转换为了文件流,为的是能让服务端得到你上传的文件的文件流。当然,你填写的一些文本信息也变成了流,用request.getParameter()方法当然得不到值了  

  用request.getInputStream()来接收流数据吧......
答案就在这里:ENCTYPE=multipart-form-data

也可能是你服务器的错误。你用的语言/框架是什么。

你的到底是添加页面报测错误还是列表?意思是你的添加那个页面提交了2次数据到保存页面,一次又数据一次没有?自己检查下js是不是做了什么操作了,怎么会提交了了2次

我觉得你可能是页面提交有问题吧,不然怎么会自己提交两次呢
