處理後的渲染視圖Express/POST

-1

我試圖在處理上傳的Multer文件後渲染視圖。我得到了一個錯誤處理後的渲染視圖Express/POST

Unhandled promise rejection (rejection id: 1): TypeError: res.redirect is not a function

做我明白了什麼錯？還應用從來不知道botom渲染爲 'step2.ejs'

app.post('/vision/upload', upload.single("upl"), function(req, res) { 
var file = req.file; 
filePath = req.file.path; 
const req2 = new vision.Request({ 
    image: new vision.Image(file), 
    features: [ 
     new vision.Feature('DOCUMENT_TEXT_DETECTION', 10), 
    ] 
}); 
vision.annotate(req2).then((res) => { 
    p1 = JSON.stringify(res.responses); 
p1up = p1.toUpperCase(); 
occurrencesText = new Occurrences(p1up); 
console.log(occurrencesText); 
connection.query(queryString, function(err, rows, fields) { 
    if (err) throw err; 
    for (var i in rows) { 
     var occurence = stringOccurrence(p1up, rows[i].name); 
     var fuzzy = fuzzysearch(rows[i].name, p1up); 
     if(fuzzy = true){ 
      arrayResults.push([rows[i].name, occurence]); 
     } 
     // 
    } 
}); 
res.render('step2.ejs', { 
    results: arrayResults, 
    "filePath": filePath 
});

}） }）;

你是否在自己的某個地方調用'res.redirect（）'？ – alex

不，唯一的其他res.render（甚至沒有redirec）我有家'route.app.get（'/ home'，函數（req，res）{res.render（'uploadform.ejs'）; }）;' –
