0.前言
好久沒在CSDN上寫東西了，看了之前開發的下載器由於三個網站程式碼更新已經不能用了，應要求，重分析了三個網站播放機制，寫了1.2版本的下載器，在我的資源裡有下載。 貼個地址:https://download.csdn.net/download/mnikkqqw/10663205
1.程式碼更新
這次程式碼更新，引入了Newtonsoft.Json.dll解析json檔案，以前那個是自己寫的解析器，太麻煩，用別人現成的就行。核心業務程式碼基本沒有變動，只是更新了分析網站資源的程式碼，解決了一下之前列表欄滾動條不可用的問題，工具還是有很多問題的，不影響使用沒改。 分析和新增喜馬拉雅音訊的程式碼：
if (ResourceBox.Lines[i].IndexOf("ximalaya") > -1) //處理喜馬拉雅FM下載地址
{
try
{
string url = ResourceBox.Lines[i];
string html = CommonMethds.GetHttpWebRequest(url);
Regex reg = new Regex(@"(?m)<h2 class=""dOi2""[^>]*>(?<span>(?:\w|\W)*?)</h2[^>]*>" 分析和新增蜻蜓音訊的程式碼：
else if (ResourceBox.Lines[i].IndexOf("qingting") > -1) //處理蜻蜓FM下載地址
{
try
{
string url = ResourceBox.Lines[i];
string html = CommonMethds.GetHttpWebRequest(url);
Regex reg = new Regex(@"(?m)<span class=""_1QL0"" data-reactid=""73""[^>]*>(?<span>(?:\w|\W)*?)</span[^>]*>", RegexOptions.Multiline | RegexOptions.IgnoreCase);
Match mc = reg.Match(html);
string temp = mc.Groups["span"].Value.Trim();
temp = temp.Replace("<!-- react-text: 74 -->共<!-- /react-text --><!-- react-text: 75 -->", "").Replace("<!-- /react-text --><!-- react-text: 76 -->個節目<!-- /react-text -->", "");
int ResoucesCount = int.Parse(temp);
int pageCount = ResoucesCount / 10 + 1;
for (int k = 1; k <= pageCount; k++)
{
string tempUrl = url.Replace("http://www.qingting.fm", "http://i.qingting.fm/wapi") + "/programs/page/" + k + "/pagesize/10";
string JsonSources = CommonMethds.GetHttpWebRequest(tempUrl);
JObject jobj = (JObject)JsonConvert.DeserializeObject(JsonSources);
string data = jobj["data"].ToString();
JArray soundInfos = (JArray)JsonConvert.DeserializeObject(data);
int count = soundInfos.Count;
for (int j = 0; j < count; j++)
{
//防止datagridview假死導致滾動條不可用
Invoke(new Action(delegate
{
//繫結datagridview程式碼
JToken tempObj = soundInfos[j];
if (tempObj["file_path"].ToString() != "null" && tempObj["file_path"].ToString() != "")
{
int index = DownloadList.Rows.Add();
DownloadList.Rows[index].Cells[0].Value = true;
DownloadList.Rows[index].Cells[1].Value = tempObj["channel_id"].ToString();
DownloadList.Rows[index].Cells[2].Value = tempObj["channel_id"].ToString();
DownloadList.Rows[index].Cells[3].Value = "[" + ((k - 1) * 10 + j + 1) + "]" + tempObj["name"].ToString();
DownloadList.Rows[index].Cells[4].Value = "http://od.qingting.fm/" + tempObj["file_path"].ToString();
string duration = tempObj["duration"].ToString();
duration = duration.Substring(0, duration.IndexOf("."));
DownloadList.Rows[index].Cells[5].Value = Int32.Parse(duration) / 60 + "分" + Int32.Parse(duration) % 60 + "秒";
DownloadList.Rows[index].Cells[6].Value = "";
DownloadList.Rows[index].Cells[7].Value = "";
DownloadList.Rows[index].Cells[8].Value = "0%";
}
}));
State.Text = "正在分析第" + (i + 1) + "個源網頁下載地址，已完成" + ((k - 1) * 10 + j) + "/" + ResoucesCount + "，請稍等……";
}
}
}
catch (Exception ex)
{
MessageBox.Show("請確認輸入網址符合輸入規則且電腦正確聯網！");
}
}分析和新增荔枝音訊的程式碼：
else if (ResourceBox.Lines[i].IndexOf("lizhi") > -1) //處理荔枝FM下載地址
{
try
{
string url = ResourceBox.Lines[i];
string html = CommonMethds.GetHttpWebRequest(url);
Regex reg = new Regex(@"\（[1-9]\d*\）", RegexOptions.Multiline | RegexOptions.IgnoreCase);
Match mc = reg.Match(html);
mc = reg.Match(html);
string temp = mc.Value.Trim();
temp = temp.Replace("（", "").Replace("）", "");
int ResoucesCount = int.Parse(temp);
int pageCount = ResoucesCount / 20 + 1;
for (int k = 1; k <= pageCount; k++)
{
string tempUrl = url + "/p/" + k + ".html";
string webSources = CommonMethds.GetHttpWebRequest(tempUrl);
webSources = webSources.Substring(webSources.IndexOf(@"<ul class=""audioList fontYaHei js-audio-list"">"));
//專輯編號
List<string> radioID = CommonMethds.GetHtmlAttr(webSources, "a", "data-uid");
//專輯名稱
List<string> radioName = CommonMethds.GetHtmlAttr(webSources, "a", "data-radio-name");
//檔名稱
List<string> audioName = CommonMethds.GetHtmlAttr(webSources, "a", "data-title");
//檔案編號，用於獲取下載地址
List<string> audioID = CommonMethds.GetHtmlAttr(webSources, "a", "data-id");
//檔案時長
List<string> audioDuration = CommonMethds.GetHtmlAttr(webSources, "a", "data-duration");
for (int j = 0; j < audioID.Count; j++)
{
//防止datagridview假死導致滾動條不可用
Invoke(new Action(delegate
{
string JsonUrl = "http://www.lizhi.fm/media/url/" + audioID[j];
string json = CommonMethds.GetHttpWebRequest(JsonUrl);
JObject jobj = (JObject)JsonConvert.DeserializeObject(json);
string data = jobj["data"].ToString();
JObject soundUrl = (JObject)JsonConvert.DeserializeObject(data);
string audioUrl = soundUrl["url"].ToString();
if (audioUrl != "null" && audioUrl != "")
{
//繫結datagridview程式碼
int index = DownloadList.Rows.Add();
DownloadList.Rows[index].Cells[0].Value = true;
DownloadList.Rows[index].Cells[1].Value = radioID[j];
DownloadList.Rows[index].Cells[2].Value = radioName[j];
DownloadList.Rows[index].Cells[3].Value = "[" + ((k - 1) * 20 + j + 1) + "]" + audioName[j];
DownloadList.Rows[index].Cells[4].Value = audioUrl;
DownloadList.Rows[index].Cells[5].Value = Int32.Parse(audioDuration[j]) / 60 + "分" + Int32.Parse(audioDuration[j]) % 60 + "秒";
DownloadList.Rows[index].Cells[6].Value = "";
DownloadList.Rows[index].Cells[7].Value = "";
DownloadList.Rows[index].Cells[8].Value = "0%";
}
}));
State.Text = "正在分析第" + (i + 1) + "個源網頁下載地址，已完成" + ((k - 1) * 20 + j) + "/" + ResoucesCount + "，請稍等……";
}
}
}
catch (Exception ex)
{
MessageBox.Show("請確認輸入網址符合輸入規則且電腦正確聯網！");
}
}原理幾乎沒有變，就是分析下載地址需要有點耐心。
2.後記
工具使用過程中因為源音訊本身不存在，會出現部分音訊下載失敗，一直卡在那個位置，只需要取消該音訊的下載繼續下其他的就可以。 如工具侵犯了您的合法權益，請郵箱聯絡我：[email protected]
