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);returnuuid + type } catch (Exception e) { return "上传失败" }
