豆瓣好像禁了小程序的接口調(diào)用，返回403錯(cuò)誤。網(wǎng)上查了一圈豆瓣應(yīng)該是通過headers里的referer判斷的。

可是wx.request(OBJECT)又不能更改referer。

網(wǎng)上都是用nginx來搞的，無奈我這菜B還不會(huì)用。。。

所以就自己試著用node做服務(wù)器代理。

上代碼：

    var express = require("express");
    var app = express();
    var proxy = require("http-proxy-middleware");
    var cors = require("cors");
    var apiproxy = [proxy("/v2/movie/top250", {
        target: "https://api.douban.com",
        changeOrigin: true
    }), proxy("/*", {
        target: "http://localhost:3000",
        changeOrigin: true
    })];

    app.use(cors());
    app.use((req, res, next) => {
        req.headers = {
            "accept": "*/*",
            "accept-encoding": "gzip, deflate, sdch, br",
            "accept-language": "zh-CN,zh;q=0.8",
            "cache-control": "no-cache",
            "connection": "keep-alive",
            "host": "localhost:5000",
            "origin": "http://localhost:8080",
            "pragma": "no-cache",
            "referer": "http://localhost:8080/",
            "user-agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36"
        }
        next();
    });
    app.use((req, res, next) => {
        console.log(req.headers.referer);
        next();
    })
    app.use(apiproxy);


    app.listen(5000, () => {
        console.log("port on 5000")
    });

寫了個(gè)中間件，headers的設(shè)置直接用了普通瀏覽器里請(qǐng)求api的設(shè)置。

    wx.request({
      url: "http://localhost:5000/v2/movie/top250",
      success(res) {
        console.log(res.data);
      }
    })

搞定！
