过去几天，我一直在为此苦苦挣扎，但是...当我从slack应用程序使用我的命令调用Slack Slash Commands时，Slack不会以任何有关该命令的数据作为响应，例如trigger_id。我想通过调用dialog.open来响应命令，但这需要命令中的trigger_id。
当前，我正在记录服务器的响应；打印出以下内容（我将其托管在Heroku中，因此这四个数字与一个时间戳有关，我无法轻松地从日志中完全删除该时间戳，只是忽略它们。我也从一开始就省略了很大一部分）由于StackOverflow的字符数限制而产生的响应）：

2178 methods: { post: true } },
2179 body: {} }
根据我看过的所有文档，示例和教程，我应该从请求的主体中获取trigger_id，并且我认为我应该能够从响应参数中获取数据。但是，请求中的参数，查询和正文都是空的。
示例：https://github.com/slackapi/template-slash-command-and-dialogs
作为旁注：我没有明确遵循本教程或使用示例；我指的是他们做了什么，以找出我做错了什么。
1995 params: {},
1996 query: {}
和
2179 body: {}
那么应该在正文，查询或参数中包含数据吗？我相信从网上看到的内容都是如此，但这是我第一次尝试使用Slack僵尸程序，至少从我所看到的内容来看，Slack没有最好的文档，因此我以某种方式将其称为错误是很合理的吗？ ？
更新，这是我在服务器上调用的路由：
app.post('/create', jsonParser, function(req, res) {
console.log(req);
var {
text, trigger_id
} = req.body;
// if (reqBody.token != botToken) {
// res.status(403).end("Access forbidden")
// } else {
res.status(200).end() // best practice to respond with empty 200 status code
//Sample Dialog response from the GitHub example, to test if route is working
const dialog = {
token: botToken,
trigger_id: trigger_id,
dialog: JSON.stringify({
title: 'Submit a helpdesk ticket',
callback_id: 'submit-ticket',
submit_label: 'Submit',
elements: [{
label: 'Title',
type: 'text',
name: 'title',
value: text,
hint: '30 second summary of the problem',
}, {
label: 'Description',
type: 'textarea',
name: 'description',
optional: true,
}, {
label: 'Urgency',
type: 'select',
name: 'urgency',
options: [{
label: 'Low',
value: 'Low'
}, {
label: 'Medium',
value: 'Medium'
}, {
label: 'High',
value: 'High'
}, ],
}, ],
}),
};
// open the dialog by calling dialogs.open method and sending the payload
bot.dialog.open({
dialog
}).then(console.log)
});
答案 0 :(得分：1)
您的身体为空的原因是您当前的代码假定来自Slack的请求按JSON编码发送。而是将其编码为标准POST请求（application/x-www-form-urlencoded）。
替换
app.post('/create', jsonParser, function(req, res) {
使用
app.use(bodyParser.urlencoded({ extended: true }))
可以解决问题。
