我这什么API都拿不到数据，偶尔两次拿到歌单信息😅

nondanee commented 6 years ago

我只能保证给你demo的commit里aes和rsa的加密结果都是正确的，请求代码你也没给…不知道你用浏览器实现的话是怎么解决xhr跨域问题的…做chrome扩展？nw.js？electron？还是其他？

zhaowweny commented 6 years ago

@nondanee 我是swift做的macOS应用，请求这块是swift做的，但是我参数用浏览器里面拿到的参数是可以正常获取数据的，换成自动生成的参数就都不行了，但是也出现过两次成功的，所以真的很困惑。给你我请求部分的代码文件。

import Foundation

    var resultDict: NSMutableDictionary
}
var resultJsonDict = ResultJsonDict(resultDict: NSMutableDictionary())

class GetPostRequestUtils: NSDictionary {

    var result: NSDictionary = NSDictionary()

    func POST(reqUrl: String, reqArgs: String, type: String) {
        let url: NSURL = NSURL(string: reqUrl)!
        let request: NSMutableURLRequest = NSMutableURLRequest(url: url as URL)

        //4.修改请求方法为POST
        request.httpMethod = "POST"

        //5.设置请求体
        request.allHTTPHeaderFields = [
            "Accept": "*/*",
            "Accept-Language": "zh-CN,zh;q=0.8,gl;q=0.6,zh-TW;q=0.4",

    ];

    var num = Int(arc4random_uniform(UInt32(userAgentList.count)));
    return userAgentList[num];
}

下面是调用的部分：

if let dic = message.body as? NSDictionary {
                let params: String = (dic["params"] as AnyObject).description
                let encSecKey: String = (dic["encSecKey"] as AnyObject).description

                let reqArgs = "params=" + params + "&encSecKey=" + encSecKey
                let reqUrl = "http://music.163.com/weapi/v3/playlist/detail?csrf_token="

                let getPostRequestUtils = GetPostRequestUtils()
                getPostRequestUtils.POST(reqUrl: reqUrl, reqArgs: reqArgs, type: "getPlaylistDetail")
                if let jsonString = resultJsonDict.resultDict.value(forKey: "getPlaylistDetail") {
                    self.subWebView.evaluateJavaScript("setPlaylistDetail(\(jsonString))") { (result, error) in
                        if (error != nil) {
                            print("\(String(describing: error))")
                        } else if (result != nil)  {
                            print(result as Any)
                        }
                    }
                }
            }

最后是js部分调用swift：

function getPlaylistDetail() {
        const data = {
            "id": playlistId,
            "offset": 0,
            "total": 1000,
            "n": 1000,
            "limit": 1000,
            "csrf_token": ""
        };
        try{
            webkit.messageHandlers.getPlaylistDetail.postMessage(Encrypt(data))
        }catch(error){
            console.error('The native context not exist ')
        }
    }

顺便提两个小问题，点击封面图展开歌曲列表部分希望设置一个最大高度，要不然歌单歌曲太多了，查看不方便，还有希望点击封面图后可以把这一行封面图滚动到窗口上方，如果封面图在窗口底部，那么点击后展开的部分还得滑动才能看到。最后麻烦您打包一下最新版的Mac版，上一个版本听不了歌😢谢谢！

nondanee commented 6 years ago

你看看是不是reqArgs拼两个参数前需要encodeURIComponent 在js里这样实现

var dataEncrypt = Encrypt(data)
var params = "params=" + encodeURIComponent(dataEncrypt.params) + "&encSecKey=" + encodeURIComponent(dataEncrypt.encSecKey)
webkit.messageHandlers.getPlaylistDetail.postMessage(params)

nondanee commented 6 years ago

UI是参照Groove Music做的，以后也不大会改主要是传包要等好久，所以懒着打了😂等等去打一下

zhaowweny commented 6 years ago

@nondanee 果然是要用encodeURIComponent处理一下🤣🤣🤣困扰我好长时间了，非常感谢，不过不明白就是一个字符串参数怎么还要处理。。。可能是swift请求部分处理参数了，所以导致发出去的参数不对。
