我正在尝试一个简单的程序来调用对后端的调用&得到回复,这是我的node.js代码:
'use strict';
var util = require('util');
var http = require('http');
var request = require('request');
var stream = require('stream');
module.exports = {
summary:summary
}
function summary(request, response) {
var id = request.swagger.params.id.value;
var url = "http://localhost:8080/test-org/myApp/summaries?q='id'";
console.log('Executing request: '+url);
request.get(url).pipe(response);
};
但是我收到以下错误:
curl http://localhost:10010/v1/customers/1123/summary
Executing request: http://localhost:8080/test-org/myApp/summaries?q='
id'
TypeError: Cannot call method 'pipe' of undefined

我缺少一些我需要下载的npm包吗?

你正在打破范围界定。您的功能需要request
,但您还加载了var request = require('request')
。
将其更改为:
var request = require('request');
function summary(req, res) {
request.get(url).pipe(res);
}

TypeError: Cannot call method 'pipe' of undefined
表示request.get(url)
返回undefined
。是的,你无法调用undefined
对象上的任何函数。
那么,为什么request.get
导致未定义?
您可以修改代码以包含一些调试吗?
request.get(url)
.on('error', function(err) {
console.log(err)
})
.pipe(response);

https://www.npmjs.org/package/request列出了16个依赖项,但它们应该自动下载。
