步骤
- connect-multiparty拿出临时缓存文件
- 换取qiniu的token上传凭证
- request.js/needle.js模块上传
方法一，使用request.js模块
// 临时文件完整路径
var file_url = req.files.file.path;
// 截取文件名
var filename = path.basename(file_url);
console.log(filename)
// 获取后缀名

/*获取token*/

/* 通过request七牛上传 */
var request = require('request');
request.post({

}, function optionalCallback(err, httpResponse, body) {

var body = JSON.parse(body);
var result = {
filename: filename,

};
res.send(result);
});
方法二，使用needle.js模块
var needle = require('needle');
var data = {
file: { file: file_url, content_type: mimeTypes[extension] },
token: uploadToken
}
var options = {
multipart: true
}
needle.post('http://upload.qiniu.com', data, options, function(err, resp, body) {
if (err) {
console.log(err);
}
console.log(body);
var result = {
filename: filename,
url: 'http://oe37p1ndi.bkt.clouddn.com/' + body.hash
};
res.send(result);
});
