Node.js 调用 restful webservice

Posted 2020-08-14

 

如何构建一个restful web service参考原来的文章

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

直接用原来的项目编译好像有问题,此处耗费1个半钟头,新建立一个项目就完全OK了 :-(

 

写一个callrest.js,代码如下:

var http = require(‘http‘); var equal = require(‘assert‘).equal; var username = ‘falcon‘; var password = ‘‘; var _auth = ‘Basic ‘ + new Buffer(username + ‘:‘ + password).toString(‘base64‘) 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‘ } }; var req = http.request(options, function (res) { console.log(‘STATUS: ‘ + res.statusCode); equal(200, res.statusCode); console.log(‘HEADERS: ‘ + JSON.stringify(res.headers)); res.on(‘data‘,function (chunk) { console.log(‘BODY: ‘ + chunk); }); });   req.on(‘error‘, function(e) { console.log(‘problem with request: ‘ + e.message); }); req.end();

 

之前在设置‘content-type‘: "application/atom+xml",结果得到错误

STATUS: 415,查了后是返回的格式不支持,然后修改为application/json或者application/xml就通过了,因为后端restful代码写的是

application/json和application/xml

执行node callrest.js输出如下:

[[email protected] nodejs-cluster]$ node callrest.js
