uni-app中上传图片报"statusCode": 400, "errMsg": "uploadFile:ok"

uni.chooseImage({
count: 10, //默认9
sourceType: ['album'], //从相册选择
success:(res)=> {
// 创建一个空的 Promises 数组
const uploadPromises = [];
uni.showLoading({
title: '图片上传中'
});
let igmFileList = res.tempFilePaths;
for(let k=0;k<igmFileList.length;k++){
const promise = new Promise((resolve, reject) => {
uni.uploadFile({
url: this.$base.baseUrl + "uploadBannerImg",
formData: {
userName: encodeURIComponent(encodeURIComponent(this.userName)),
orderId: this.orderId,
},
name: 'file',
filePath: igmFileList[k],
success: (res) => {
console.log('Upload success:', res);
resolve(res.data);
},
fail: (error) => {
console.log('Upload failed:', error);
reject(error);
}
});
})
uploadPromises.push(promise);
}
// 使用 Promise.all 等待所有文件上传完成
Promise.all(uploadPromises).then(() => {
uni.hideLoading();
// 所有文件上传完成后执行查询操作
this.getDataList();
}).catch((error) => {
console.log('文件上传失败:', error);
});

}
});

该方法是uni-app从相册中选择图片到上传图片的完整代码。在另外一个项目中是能上传图片的但是在这个项目中就不行了。附上另外一个项目的后端代码

    @RequestMapping(value = "/uploadBannerImg", headers = "content-type=multipart/form-data", method = RequestMethod.POST)
    public @ResponseBody
    String commerceUploadBannerImg(
            HttpServletRequest request,
            HttpServletResponse response,
            @RequestParam("file") MultipartFile[] file,
            @RequestParam(value = "userName", required = false) String userName,
            @RequestParam(value = "orderId", required = false) String orderId
    ) {
        try {
            response.setHeader("Access-Control-Allow-Origin", "*");
            response.setContentType("text/html;charset=UTF-8");
            for (MultipartFile multipartFile : file) {
                HashMap<String, String> attMap = new HashMap<String, String>();

                //获取前端上传的文件名称
                String fileAllName = multipartFile.getOriginalFilename();
                //获取文件名
                String fileName = fileAllName.substring(0, fileAllName.lastIndexOf("."));
                //取文件后缀
                String ext = fileAllName.substring(fileAllName.lastIndexOf(".") + 1);
                //取一个随机id给文件重命名使用
                String fileNewName = StringTools.getUUID();
                //你的接收的文件新的名字
                String fileNewPath = fileNewName + "." + ext;
                //获取项目的绝对路径
                String path = uploadResource.getFile().getPath()+ File.separator + orderId+ File.separator;
                //在项目新建一个 你重新生成名称的文件
                File fil = new File(path + fileNewPath);
                fil.mkdirs();
                multipartFile.transferTo(fil);
                //创建压缩图片
                String filePath =  request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + "/restaurant" + "/upload/banner/"+orderId+"/" + fileNewPath;
                attMap.put("shopId", shopId);
                attMap.put("fileDes", fileName);
                attMap.put("filePath", filePath);
                attMap.put("fileName", fileNewName);
                attMap.put("fileNameOld", fileName);
                attMap.put("file_type", ext);
                attMap.put("fileMd5", md5);
                attMap.put("fileType", ext);
                attMap.put("creator", RaStringUtils.decrypt(userName));
                service.addOrderImg(attMap);
            }
            return "ok";
        } catch (Exception e) {
            e.printStackTrace();
            log.error(e.toString());
            return "err";
        }
    }
这个方法在上一个项目中是能用的。如果你粘贴后直接能用就不用向下看了。在这个项目中不能用估计是哪一个配置有问题导致一直报

"data": "http://...:....",
"statusCode": 400,
"errMsg": "uploadFile:ok"

这个错误。一时间又找不了那个配置。不过我不管。

我可是有3年开发经验的程序员呢，什么场面没有见过。我管你这那的

 

}

这个是修改后的后台代码直接解决问题
