Node.js: TypeError: object is not a function
提问by R0b0tn1k
I have a weird error:
我有一个奇怪的错误：
var http = require("http");
var request = require("request");
http.createServer(function(request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Print the google web page.
}
});
response.end();
}).listen(8888);
The idea is for it to listen as a webserver, and then do a request. But this is what I get as error:
这个想法是让它作为网络服务器监听，然后发出请求。但这就是我得到的错误：
request('http://www.google.com', function (error, response, body) {
^

What am I doing wrong? I installed request, so that's not it :)
我究竟做错了什么？我安装了请求，所以不是这样:)

Access to the requestglobal variable is lost as you have a local variable with the same name. Renaming either one of the variables will solve this issue:
request由于您有一个同名的局部变量，因此无法访问全局变量。重命名任一变量将解决此问题：
var http = require("http"); var request = require("request");
http.createServer(function(req, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Print the google web page.
}
})
response.end();
}).listen(8888);

You are no longer able to access the global variable 'request'. You need to rename your local variable 'request' with some other name and the problem will be resolved.
您无法再访问全局变量“请求”。您需要使用其他名称重命名本地变量“请求”，问题将得到解决。
