Question

我正在尝试复制facebook messenger bot，但不断获得function callSendAPI(messageData) { request({ uri: 'https://graph.facebook.com/v2.6/me/messages', qs: { access_token: PAGE_ACCESS_TOKEN }, method: 'POST', json: messageData }, function (error, response, body) { if (!error && response.statusCode == 200) { var recipientId = body.recipient_id; var messageId = body.message_id; console.log("Successfully sent generic message with id %s to recipient %s", messageId, recipientId); } else { console.error("Unable to send message."); console.error(response); console.error(error); } }); }。

与Facebook相同的代码：

server.js

我的节点const express = require('express'); const bodyParser = require('body-parser'); //const request = express.request; const PAGE_ACCESS_TOKEN = 'abc'; let app = express(); app.use(bodyParser.urlencoded({ extended: false })); // parse application/json app.use(bodyParser.json()); [...] function sendTextMessage(recipientId, messageText) { var messageData = { recipient: { id: recipientId }, message: { text: messageText } }; callSendAPI(messageData); } function callSendAPI(messageData) {..} [...]如下所示：

library(tidyverse)

mt_make %>% 
  mutate(l = map(l, ~filter(.x, cyl == 6)), 
         m = map(m, ~filter(.x, hp > 150)), 
         n = map2(l, m, inner_join)) %>%    # collect data where l and m have data
  unnest(n)

mt_id %>% 
  mutate(l = map(l, ~filter(.x, make == 'Merc')), 
         m = map(m, ~filter(.x, hp < 200))) %>% 
  filter(map_int(l, nrow) == map_int(m, nrow)) %>%    # assumes your data is parallel, which suggests there's no point to nesting
  unnest()

我是否遗漏了快递？感谢

Answer 1

此示例正在使用third-party Request module。

你也可以像require('http').request()一样使用request，如果你愿意，但我会说， request 模块很常见，而且很好使用工具。

编辑 ~~实际上，我只是注意到你的代码中有它，但它被注释掉了！~~经过更长时间的浏览后，你注释掉了express.request指向request()，如果像http.request一样使用会抛出错误，因为它不是函数。因此，您应该使用Request模块，或者调整代码以使用本机/opt。

Answer 2

您未安装了request模块。

首先npm install --save request安装它，然后包括它var request = require('request');

ReferenceError：未定义请求
