本地上传图片正常，部署到 nginx 上就会出现图片上传不完整,这是nginx问题还是我写的node的代码问题?

Question

问题描述

本地上传图片正常，只要部署到nginx超过100KB大小就会出现图片上传不完整。
nginx日志里没有报错，node也没报错。

问题出现的环境背景及自己尝试过哪些方法

操作系统是Windows,我尝试过百度修改nginx里面的配置文件，但是目前没发现有效果，是不是我没修改对？
刚才尝试了一下Apache上传，发现可以正常上传。

相关代码

// 请把代码文本粘贴到下方（请勿用图片代替代码）

async upload_Img() {
    console.log('开始上传');
    const {
        ctx
    } = this;
    const stream = await ctx.getFileStream();
    if (!stream) {
        ctx.throw(403, '文件不存在或者文件错误');
        return false;
    }

    const date = await this.fliteDate(new Date());
    const folder = `app/public/upload/img/${date}`;
    const filename = new Date().getTime() + stream.filename;
    const target = path.join(`${folder}/${filename}`);
    let data = {};
    const result = await new Promise((resolve, reject) => {
        fs.access(folder, fs.constants.F_OK, err => {
            if (err) {
                fs.mkdir(folder);
            }
            const remoteFileStream = fs.createWriteStream(target);
            const upwin = stream.pipe(remoteFileStream);
            console.log('上传成功');
            console.log(upwin);
            if (upwin) {
                const path = upwin.path.match(/public(.*)/g);
                data = {
                    code: 0,
                    msg: '图片上传成功',
                    data: {
                        src: ctx.app.config.hostConfig.host + path[0]
                    }
                };
                resolve(data);
            }
            reject('上传失败');
        });
    });
    return result;
}
