[英]Http Post with node.js and express
I am just trying to write a simple node.js app that will be able to write to a file via post and access that file with the express.static(). 我只是在尝试编写一个简单的node.js应用程序,该应用程序将能够通过发布写入文件并使用express.static()访问该文件。
var express = require('express'),
fs = require('fs')
url = require('url');
var app = express();
app.configure(function(){
app.use('/public', express.static(__dirname + '/public'));
app.use(express.static(__dirname + '/public'));
app.use(express.bodyParser());
});
app.post('/receieve', function(request, respond) {
filePath = __dirname + '/public/data.txt';
fs.appendFile(filePath, request.body)
});
app.listen(1110);
I'm using postman chrome extension to test if my post is working correctly, but I'm receiving 'cannot POST /receive' when I try to send raw json. 我正在使用邮递员 chrome扩展程序来测试我的帖子是否正常工作,但是当我尝试发送原始json时我收到了“无法发布/接收”消息。 Any ideas of what the problem could be?
关于问题可能有什么想法? Thank you!
谢谢!
As go-oleg mentioned, there's a mismatch between the server-side route and the client-side request: 正如go-oleg所述,服务器端路由和客户端请求之间存在不匹配:
'/receive' !== '/receieve' // extra `e` in the route
You may also want to specify a format when appending request.body
. 您可能还希望在附加
request.body
时指定一种格式。 Object#toString
, which appendFile()
will use, simply generates "[object Object]"
. appendFile()
将使用的Object#toString
仅生成"[object Object]"
。
fs.appendFile(filePath, JSON.stringify(request.body));
And, you should .end()
the response
at some point: 并且,您应该在某点上使用
.end()
response
:
fs.appendFile(filePath, JSON.stringify(request.body));
response.end();
fs.appendFile(filePath, JSON.stringify(request.body), function () {
response.end();
});
You can also use .send()
if you want to include a message in the response
. 如果您想在
response
包含一条消息,也可以使用.send()
。 It'll call .end()
. 它将调用
.end()
。
