小程序代码

upload:function(e){

var that = this;

wx.showActionSheet({

itemList: [‘从相册选择‘,‘拍照‘],

itemColor:"#f7982a",

success:function(res){

if(!res.cancer){

if (res.tapIndex==0){

that.chooseWxImageShop(‘album‘);

} else if (res.tapIndex == 1) {

that.chooseWxImageShop(‘camera‘)

}

}

}

})

},

chooseWxImageShop: function (type) {

var that = this;

wx.chooseImage({

sizeType: [‘original‘, ‘compressed‘],

sourceType: [type],

success: function (res) {

/*上传单张

that.data.orderDetail.shopImage = res.tempFilePaths[0],

that.upload_file(API_URL + ‘shop/shopIcon‘, res.tempFilePaths[0])

*/

// 上传多张(遍历数组，一次传一张)

for (var index in res.tempFilePaths) {

that.upload_file(‘后台接口地址‘, res.tempFilePaths[index])

}

}

})

},

upload_file: function (url, filePath) {

var that = this;

wx.uploadFile({

url: url,

filePath: filePath,

name: ‘imagefile‘,

header: {

‘content-type‘: ‘multipart/form-data‘

}, // 设置请求的 header

formData: { ‘guid‘:"procomment" }, // HTTP 请求中其他额外的 form data

success: function (res) {

console.log(JSON.parse(res.data).msg)

},

fail: function (res) {

}

})

}

后台代码

public String doUpload(HttpServletRequest request, HttpServletResponse response, @RequestParam(value = "imagefile", required = false) MultipartFile imagefile) throws Exception { try { String uuid = UUIDGenerator.build();String type = imagefile.getOriginalFilename().substring(imagefile.getOriginalFilename().lastIndexOf(".")).toLowerCase(); File targetFile = new File("D:/images/upload/" , uuid + type); if (!targetFile.exists()) { targetFile.mkdirs(); } imagefile.transferTo(targetFile);return uuid + type } catch (Exception e) { return "上传失败" }
