javascript - fs readFilesync 错误路径必须是字符串

Question

我有一个上传文件的代码这里是代码:

            var oriPath = JSON.stringify(req.files.profilePicture);
            var data = fs.readFileSync(oriPath.path);
            var ext = path.extname(oriPath.name);
            if (!ext) {
                return next(err);
            }

            var newName = Date.now().toString() + ext;
            var path = config.fullhostname + config.uploadDir + newName;
            if (!fs.writeFileSync(path, data)) {
                return next("Failed to upload image", 400)
            }

并显示如下错误:uncaughtException TypeError:路径必须是字符串引用var data = fs.readFileSync(oriPath.path);

但文件上传成功，如何解决？谢谢

尝试强制字符串转换:

var data = fs.readFileSync(String(oriPath.path))
