NodeJS request 使用方法

安装

npm install --save request

GET请求
var request = require(‘request’);
request(‘http://www.baidu.com’, function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Show the HTML for the baidu homepage.
}
})
POST application/json
request({
url: url,
method: “POST”,
json: true,
headers: {
“content-type”: “application/json”,
},
body: JSON.stringify(requestData)
}, function(error, response, body) {
if (!error && response.statusCode == 200) {
}
});
POST application/x-www-form-urlencoded
request.post({url:’http://service.com/upload’, form:{key:’value’}}, function(error, response, body) {
if (!error && response.statusCode == 200) {
}
})
POST multipart/form-data
var formData = {
// Pass a simple key-value pair
my_field: ‘my_value’,
// Pass data via Buffers
my_buffer: new Buffer([1, 2, 3]),
// Pass data via Streams
my_file: fs.createReadStream(__dirname + ‘/unicycle.jpg’),
};
request.post({url:’http://service.com/upload’, formData: formData}, function (error, response, body) {
if (!error && response.statusCode == 200) {
}
})
formData可以直接放key-value格式的数据，也可以放buffer，或者是通过流描述的文件。
