[Feature Request] Uploader读取上传图片，异常的慢

[vekee]

What problem does this feature solve?

图片大小约5MB
上传时间超过30秒

其他地方测试过上传URL，同样文件几乎瞬间上传完毕。
Uploader可能再读取文件方面，影响了速度？

长传URL的前后全部输出日志，确定只在上传环节影响了速度。
又是本地开发，而上传URL以及网速都用同样文件确认过，没有问题。

What does the proposed API look like?

        <van-field
          name="identification_file_uploader"
          :label="文件上传"
        >
          <template #input>
            <van-uploader
              v-model="formData.identification_file_uploader"
              :max-count="2"
              accept=".jpg,.jpeg,.png,.pdf,.heic,.heif,image/*,application/pdf"
              result-type="file"
            />
          </template>
        </van-field>

@inottn
已经设置为这个，没有看源码，直观感觉是文件在前端传送前的加载，有什么不对劲

result-type="file"
