如何構建一個restful web service參考原來的文章javascript

http://www.cnblogs.com/ericnie/p/5212748.htmlhtml

直接用原來的項目編譯好像有問題,此處耗費1個半鐘頭,新創建一個項目就徹底OK了 :-(java

寫一個callrest.js,代碼以下:node

var http = require('http');
var equal = require('assert').equal;web

var username = 'falcon';
var password = '';
var _auth = 'Basic ' + new Buffer(username + ':' + password).toString('base64')json

var options = {
host: '192.168.0.101',
port: 7001,
path: '/RestfulApplication-testproject-context-root/resources/testproject/Persons',
method: 'GET',
headers:{
'accept': '*/*',
'content-type': "application/xml",
'accept-encoding': 'gzip, deflate',
'accept-language': 'en-US,en;q=0.9',
'user-agent': 'nodejs rest client'
}
};後端

var req = http.request(options, function (res) {
console.log('STATUS: ' + res.statusCode);
equal(200, res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));restful

res.on('data',function (chunk) {
console.log('BODY: ' + chunk);
});
});app

req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});ui

req.end();

以前在設置'content-type': "application/atom+xml",結果獲得錯誤

STATUS: 415,查了後是返回的格式不支持,而後修改成application/json或者application/xml就經過了,由於後端restful代碼寫的是

application/json和application/xml

執行node callrest.js輸出以下:

[weblogic@ericnie nodejs-cluster]$ node callrest.js
