文章标签 android 上传多张图片同时带参数 html 上传拖拽 文章分类 Android 移动开发

首先，操练了很久这个功能，差点给我干废，终于搞好了，所以给大家分享一下，之前找了很多例子参考，但是均有些问题，所以把我这个成品发上来。（也有很多摘录别人的）。

然后，现在网上很多例子都是半成品或者是不靠谱的，我搜索很多颇有感触，太坑人了，我这个是成品直接发上来经过测试，没问题，pc端也可以用。安卓ios都可以选择多少张图片上传。

后台：java （SSH）

前台：h5 js （有个jquery的jar包需要引入）

这里分享几张成品效果图把。

android 上传多张图片同时带参数手机多图上传_html

android 上传多张图片同时带参数手机多图上传_上传_02

android 上传多张图片同时带参数手机多图上传_android 上传多张图片同时带参数_03

这里是手机上传的，

pc端可以拖拽到里面，也可以上传，点击选取文件时自动找file 。h5自带功能，手机直接提示找相册或者拍照or视频。然后选取即可。

/**

* 这里我先把html 怼上来，放在pc页面可以拖拽，放在手机就不能拖拽了，我给删掉了，若有需要自己再加吧。移动端没有拖拽

* ~~要注意：form表单里的action。我加了注释了在上面一行。（ps：就一个斜杠“/” ，我搞了一个星期不知道哪里出的错。。。很尴尬，主要是没有错误信息）

* 接下来是最主要后台，用于提交的，走的是struts2提交的，配置等会在最后我发一下，就几句话。

* 这里要注意的：注释的一堆logger请无视，当时测试打印log费死劲了，因为我不是专门做手机的，比较业余，没有连上真机测试的软件，所以这里也不报错，也显示提交成功，也没啥问题。搞了很久
