使用Node.js连接Cloudant CouchDB? [英] Connect to Cloudant CouchDB with Node.js?
问题描述
我正在尝试使用Node.js连接到Cloudant上的CouchDB数据库。
I am trying to connect to my CouchDB database on Cloudant using Node.js.
这适用于shell:
curl https://weng:password@weng.cloudant.com/my_app/_all_docs
但是这个node.js代码不起作用:
But this node.js code didn't work:
var couchdb = http.createClient(443, 'weng:password@weng.cloudant.com', true);
var request = couchdb.request('GET', '/my_app/_all_docs', {
'Host': 'weng.cloudant.com'
});
request.end();
request.on('response', function (response) {
response.on('data', function (data) {
util.print(data);
});
});
它给了我这个数据:
{"error":"unauthorized","reason":"_reader access is required for this request"}
如何使用Node.js列出我的所有数据库?
How do I do to list all my databases with Node.js?
推荐答案
内置的Node.js http客户端非常低级,它不支持开箱即用的HTTP Basic auth。 http.createClient
的第二个参数只是一个主机名。它不会在那里期望凭证。
The built-in Node.js http client is pretty low level, it doesn't support HTTP Basic auth out of the box. The second argument to http.createClient
is just a hostname. It doesn't expect credentials in there.
您有两种选择:
1。自己构建HTTP基本授权标头
var Base64 = require('Base64');
var couchdb = http.createClient(443, 'weng.cloudant.com', true);
var request = couchdb.request('GET', '/my_app/_all_docs', {
'Host': 'weng.cloudant.com',
'Authorization': 'Basic ' + Base64.encode('weng:password')
});
request.end();
request.on('response', function (response) {
response.on('data', function (data) {
util.print(data);
});
});
您需要一个Base64库,例如一个用C语言编写的节点或一个纯JS一个(例如 CouchDB Futon使用的那个)。
You will need a Base64 lib such as one for node written in C, or a pure-JS one (e.g. the one that CouchDB Futon uses).
2。使用更高级别的Node.js HTTP客户端
更具特色的HTTP客户端,例如 Restler ,可以更轻松地完成上述请求,包括凭据:
A more featureful HTTP client, like Restler, will make it much easier to do the request above, including credentials:
var restler = require('restler');
restler.get('https://weng.cloudant.com:443/my_app/_all_docs', {
username: 'weng',
password: 'password'
}).on('complete', function (data) {
util.print(data);
});
