Cannot read property 'request' of undefined #1592

Open ygtzz opened 4 years ago

ygtzz commented 4 years ago

while I request a file from a server in koa

router.post('/proxy', async function (ctx) {
    let postParam = ctx.request.body;
    let fileName = urlencode.decode(postParam.fileName);
    let filePath = urlencode.decode(postParam.filePath);
    filePaths = filePath.split('/');
    filePaths = filePaths.slice(0,-1);
    filePath = filePaths.join('/') + '/' + postParam.fileName;
    console.log('filePath: ', filePath)

    let res = superagent.get(postParam.filePath);
    let passThroughtStream = new stream.PassThrough();
    res.pipe(passThroughtStream);

    ctx.set("Content-disposition", "attachment; filename=" + postParam.fileName);
    ctx.type = filePath.split('.')[1];
    ctx.body = passThroughtStream;
});

superagent makes error:
