upload: function (page, path) {
var that = this;
var curImgList = [];
for (var i = 0; i < path.length; i++) {
wx.showToast({
icon: "loading",
title: "正在上传"
}),
wx.uploadFile({
url: main_url + '/eop/celltest/addpicture',//接口处理在下面有写
filePath: path[i].pic,
name: 'file',
header: { "Content-Type": "multipart/form-data" },
formData: { pic: pathpath[i]},
你的后端写的是
@Param("pic_url") String pic_url,
@Param("pic") List<TempFile> tf
微信小程序要这样对应
wx.uploadFile({
url: main_url + '/eop/celltest/addpicture',//接口处理在下面有写
filePath: path[i], // 为啥你要加.pic,明显不对呀
name: 'pic', // 这里对应的字符串就是文件对应的表单名
header: { "Content-Type": "multipart/form-data" },
formData: { pic_path: path[i] } // pic_path才是路径,原本写的是pic
}
