如何使用node.js从XML类型rest API中提取数据?
这是我用来通过发送rest api请求来获取数据的代码:
//Load the request module
var request = require('request');
//Lets configure and request
request(
{
url: 'http://nemo.sonarqube.org/api/resources?resource=DEV:Fabrice%20Bellingard:org.codehaus.sonar:sonar&metrics=ncloc,coverage', //URL to hit
method: 'GET', //Specify the method
headers: { //We can define headers too
'Authorization': 'Basic ' + new Buffer( 'admin' + ':'+'admin').toString('base64'),
'Content-Type': 'MyContentType',
'Custom-Header': 'Custom Value'
}
},
function(error, response, body){
if(error) {
console.log(error);
} else {
var obj=JSON.parse(response.body);
console.log(obj.id);
}
}
)
var express = require('express');
var app = express();
var server = app.listen(3000,function (){
console.log('port 3000');
}
);
当我使用浏览器发送请求时,结果显示为:
<resources>
<resource>
<id>400009</id>
<key>DEV:Fabrice Bellingard:org.codehaus.sonar:sonar</key>
<name>SonarQube</name>
<lname>SonarQube</lname>
<scope>PRJ</scope>
<qualifier>DEV_PRJ</qualifier>
<date>2015-08-04T13:10:57+0000</date>
<creationDate/>
<copy>48569</copy>
<msr>
<key>ncloc</key>
<val>879.0</val>
<frmt_val>879</frmt_val>
</msr>
<msr>
<key>coverage</key>
<val>81.8</val>
<frmt_val>81.8%</frmt_val>
</msr>
</resource>
</resources>
我想提取 id 并使用node.js在控制台上打印它。 我想如何编辑上面的代码?
答案 0 :(得分:-1)
问题是response.body是数组格式,所以得到数组中的第一项,然后是id
值
//Load the request module
var request = require('request');
//Lets configure and request
request({
url: 'http://nemo.sonarqube.org/api/resources?resource=DEV:Fabrice%20Bellingard:org.codehaus.sonar:sonar&metrics=ncloc,coverage', //URL to hit
method: 'GET', //Specify the method
headers: { //We can define headers too
'Authorization': 'Basic ' + new Buffer('admin' + ':' + 'admin').toString('base64'),
'Content-Type': 'MyContentType',
'Custom-Header': 'Custom Value'
}
}, function (error, response, body) {
if (error) {
console.log(error);
} else {
var arr = JSON.parse(response.body);
var obj = arr[0];
console.log(obj.id);
}
})
var express = require('express');
var app = express();
var server = app.listen(3000, function () {
console.log('port 3000');;
});
