最近Nodejs,python越来越火了,同时也越来越多的人在用node写服务,可是怎么去调试服务呢?以及当你一个服务发布出去,怎么保证其安全性呢?
环境:linux unbuntu
语言:nodejs
工具:npm,mongodb,HttpIE
昨天写API的时候遇到了一个苦恼,就是我怎么去调试一个Api,当然有人会说客户端调用一下,然后debug模式就可以跟踪了,可是我昨天没有客户端,怎么办呢?后来找到了一个非常好的工具HttpIE,怎么安装可以参考 https://httpie.org/doc#linux,大家可能根据自己的开发环境去安装
example:
# Debian, Ubuntu, etc.
apt-get install httpie
# Fedora, CentOS, RHEL, …
yum install httpie
# Arch Linux
pacman -S httpie
不过万事都有不顺的时候,我在安装的时候遇到了一个问题
william@ubuntu:~$ sudo apt-get install httpie

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
cpp-5 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.2) but 5.4.0-6ubuntu1~16.04.4 is to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

报错了,原因是需要清除掉缓存
william@ubuntu:~$ sudo apt-get clean
然后重复上面的操作(蓝色字体)的命令就可以完成了
怎么用HttpIE去调试API呢,比如我需要调试添加一条article记录怎么办呢? http://localhost:1337/api/articles,
$ http POST http://localhost:1337/api/articles title=TestArticle author='John Doe' description='lorem ipsum dolar sit amet' images:='[{"kind":"thumbnail", "url":"http://habrahabr.ru/images/write-topic.png"}, {"kind":"detail", "url":"http://habrahabr.ru/images/write-topic.png"}]'
看截图:
然后进入到了virtual studio code里面的断点:
怎么保证其安全性呢? 我用的是oauth2orize, https://www.npmjs.com/package/oauth2orize
在调用的时候加入:
router.post('/', passport.authenticate('bearer', { session: false }), function(req, res) {
然后调用的时候,需要加入token:
william@ubuntu:~$ http POST http://localhost:1337/api/articles title=NewArticle author='John Doe' description='Lorem ipsum dolar sit amet' images:='[{"kind":"thumbnail", "url":"http://habrahabr.ru/images/write-topic.png"}, {"kind":"detail", "url":"http://habrahabr.ru/images/write-topic.png"}]' Authorization:'Bearer put your token here'
passport 与oauth2orize 联合使用,其中有2个重要的概念AccessToken 和 RefreshToken, 为什么有了AccessToken还需要RefreshToken呢?因为token都会过期,需要运用RefreshToken去刷新AccessToken
var oauth2orize = require('oauth2orize');
var passport = require('passport');
var crypto = require('crypto');
var libs = process.cwd() + '/libs/';
var config = require(libs + 'config');
var log = require(libs + 'log')(module);
var db = require(libs + 'db/mongoose');
var User = require(libs + 'model/user');
var AccessToken = require(libs + 'model/accessToken');
var RefreshToken = require(libs + 'model/refreshToken');
// create OAuth 2.0 server
var aserver = oauth2orize.createServer();
// Generic error handler
var errFn = function (cb, err) {
if (err) {
return cb(err);
}
};
// Destroys any old tokens and generates a new access and refresh token
var generateTokens = function (data, done) {
// curries in `done` callback so we don't need to pass it
var errorHandler = errFn.bind(undefined, done),
refreshToken,
refreshTokenValue,
token,
tokenValue;
RefreshToken.remove(data, errorHandler);
AccessToken.remove(data, errorHandler);
tokenValue = crypto.randomBytes(32).toString('hex');
refreshTokenValue = crypto.randomBytes(32).toString('hex');
data.token = tokenValue;
token = new AccessToken(data);
data.token = refreshTokenValue;
refreshToken = new RefreshToken(data);
refreshToken.save(errorHandler);
token.save(function (err) {
if (err) {
log.error(err);
return done(err);
}
done(null, tokenValue, refreshTokenValue, {
'expires_in': config.get('security:tokenLife')
});
});
};
// Exchange username & password for access token.
aserver.exchange(oauth2orize.exchange.password(function(client, username, password, scope, done) {
User.findOne({ username: username }, function(err, user) {
if (err) {
return done(err);
}
if (!user || !user.checkPassword(password)) {
return done(null, false);
}
var model = {
userId: user.userId,
clientId: client.clientId
};
generateTokens(model, done);
});
}));
// Exchange refreshToken for access token.
aserver.exchange(oauth2orize.exchange.refreshToken(function(client, refreshToken, scope, done) {
RefreshToken.findOne({ token: refreshToken, clientId: client.clientId }, function(err, token) {
if (err) {
return done(err);
}
if (!token) {
return done(null, false);
}
User.findById(token.userId, function(err, user) {
if (err) { return done(err); }
if (!user) { return done(null, false); }
var model = {
userId: user.userId,
clientId: client.clientId
};
generateTokens(model, done);
});
});
}));
// token endpoint
//
// `token` middleware handles client requests to exchange authorization grants
// for access tokens. Based on the grant type being exchanged, the above
// exchange middleware will be invoked to handle the request. Clients must
// authenticate when making requests to this endpoint.
exports.token = [
passport.authenticate(['basic', 'oauth2-client-password'], { session: false }),
aserver.token(),
aserver.errorHandler()
];
