Question

我正在編寫一個網站報廢我的研究項目。在定期瀏覽網站期間，我會提交表格並提供數據。有更多數據的下一頁的鏈接。還有一個鏈接，用於下載Excel文件中顯示的數據的數據。

我正在使用Jsoup登錄並解析網站。如何使用Jsoup或任何其他解析器或方法在Excel文件中提交和下載數據？

這是下載鏈接點擊時我收到標題：

使用java.net.URLConnection中的後發數據。

服務器響應是excel的數據。保存本地文件...

例如：

 try{ 
      String postData = "uid=1886&iss=%27on%27%2C%27AABAAD075E04C325674A0039F724%27%2C%273DC84DD11C51C32567400032199E%27%2C%27FB9900A46791499BA08BC3\CFA39%27%2C%27E21096B5CCABA8424325685700350F60%27%2C%2795345C101FAE47979E25CBF409044F11%27%2C%2791001D2C33036B8C43256735005A6F38%27%2C%27A407F1FA59BB4243A2321D1D561D05FC%27%2C%27038D4548E9E3448DA85C397BB8E7813C%27%2C%2743256B410056E49F43256B6600535ADB%27%2C%277A3678AD5AE14B0A945D0EB6B7919F6E%27%2C%273E7F2B1C9DF045C2B490D064C27012E0%27%2C%2709D6465D27A13F4443256918005508F6%27%2C%27432569290063957443256A3C002D1886%27%2C%2706303D64278B47F143256735005AB499%27%2C%2799F954C23CAB4D5884AC647F1D03A991%27%2C%273A4856543CEF4C7BA37F4CFBA837EA23%27%2C%27612B5284D9604368B86A3CFF7BF84916%27%2C%2714C8FC8A807C494C29F5DA20%27%2C%27B44C85F39BA64922BAC5E665DD9D968C%27%2C%27A4519C3DC0CB4F8E83EA3CBCB19DC60C%27%2C%2741DDBC39B3584C5CB81ABF9B3EFA91E5%27%2C%27D3068AD3F90441E7B8ABCCE5ADD12D07%27%2C%277E75E0F682AD84B4C3256763002EA999%27%2C%27A1DAA1A271404F049AB543DC7FD14CC5%27%2C%27A43E335F235F4F5CA087B2B1B42304BC%27%2C%275E7E15B019C84AA188BFB03B5C416639%27%2C%27F695456883C04C91B47D204576FA6033%27%2C%27E765622FA33F4B13AAC56348E62C69C5%27%2C%2741113AD02A6A43F9A6A6F20D0CDEA7F1%27%2C%270F36F00CC10F4E60B9226BCE04EA462B%27";
