vue2.0 高仿音樂webApp 跨域獲取數(shù)據(jù)

publicPath: config.dev.assetsPublicPath,
proxy: config.dev.proxyTable,
quiet: true, // necessary for FriendlyErrorsPlugin
watchOptions: {
  poll: config.dev.poll,
},
after(app) {
  app.get('/api/lyric', (req, res) => {
    var url = 'https://c.y.qq.com/lyric/fcgi-bin/fcg_query_lyric_new.fcg'
    axios.get(url, {
      headers: {
        referer: 'https://c.y.qq.com',
        host: 'c.y.qq.com'
      },
      params: req.query
    }).then((response) => {
      var ret = response.data
      if (typeof ret === 'string') {
        var reg = /^\w+\(({[^()]+})\)$/
        var matches = ret.match(reg)
        if (matches) {
          ret = JSON.parse(matches[1])
        }
      }
      res.json(ret)
    }).catch((e) => {
      console.log(e)
    })
  })
}

},

可以了，不行是因?yàn)閞ecommed.js有問題

可以給個(gè)視頻地址嘛~

希望將配置部分貼出來，已糾結(jié)好久，無奈node不通，謝謝了

感謝樓主,困擾了一天的問題在你這兒找到了答案. 給樓主一個(gè)棒棒噠

折騰了一天 終于搞好了，問題可能描述得不太清楚，我這里再說一遍。

如果你也看過這個(gè)視頻教程，你就會知道，老師所用的方法是在 build/dev-server.js 里面開一個(gè) express 服務(wù)器，然后它會監(jiān)聽到頁面發(fā)送的請求，如果請求地址與這里代理的地址一樣就會跳進(jìn)這個(gè)代理，代碼如下：

// 獲取 express 對象
var app = express()
// 建立一個(gè)apiRoutes
var apiRoutes = express.Router()

apiRoutes.get('/getDiscList', function (req, res) {
  var url = 'https://c.y.qq.com/splcloud/fcgi-bin/fcg_get_diss_by_tag.fcg'
  axios.get(url, {
    headers: {
      referer: 'https://c.y.qq.com/',
      host: 'c.y.qq.com'
    },
    params: req.query
  }).then((response) => {
    res.json(response.data)
  }).catch((e) => {
    console.log(e)
  })
})

apiRoutes.get('/lyric', function (req, res) {
  var url = 'https://c.y.qq.com/lyric/fcgi-bin/fcg_query_lyric_new.fcg'

  axios.get(url, {
    headers: {
      referer: 'https://c.y.qq.com/',
      host: 'c.y.qq.com'
    },
    params: req.query
  }).then((response) => {
    var ret = response.data
    if (typeof ret === 'string') {
      var reg = /^\w+\(({[^()]+})\)$/
      var matches = ret.match(reg)
      if (matches) {
        ret = JSON.parse(matches[1])
      }
    }
    res.json(ret)
  }).catch((e) => {
    console.log(e)
  })
})

// express 對象占用這個(gè)url
app.use('/api', apiRoutes)

上面是vue-cli webpack 模板 1.2.4 之前的配置方法（版本可能更前）

但是以目前最新版本的vue-cli webpack 模板來說有這樣的變化：
1、沒有了dev-server.js 和 dev-client.js
2、package.js 里面并沒有 express 和 http-proxy-middleware,我在配置的時(shí)候一直沒有留意，所以一直搞到下午才算完成。

配置之前需要npm 安裝 express 至于 http-proxy-middleware 視情況安裝吧，不過還是有用的

然后，就像以往一樣 require 一個(gè) express

最后，代碼需要這樣寫

在 devServer 里面增加一個(gè) after方法(before 方法我沒試過)：

參數(shù)調(diào)用 get 方法

然后就好像老師所說的那樣寫進(jìn)去就好了

以后通過 express服務(wù)器 作為中轉(zhuǎn)也可以這樣做

有完整的代碼嗎‘’

樓主 我也是這樣寫的，但是獲取歌單數(shù)據(jù)的時(shí)候，中文出現(xiàn)了亂碼，怎么解決啊

求完整的代碼，按照上面的操作還是不行啊

視頻地址有嗎？發(fā)一下去看看
