Google日曆 - 獲取ics文件（不含API）

我想在Java項目中從Google議程獲取ICS文件，而不使用API（只是獲取ics的內容）。日曆設置爲「公開」，我從參數中獲得公共地址（https://www.google.com/calendar/ical/perrine.lbc62%40gmail.com/public/basic.ics）。如果我在瀏覽器中嘗試此地址，我可以下載該文件（如果我沒有連接，則爲事件）。Google日曆 - 獲取ics文件（不含API）

但是，如果我嘗試使用curl命令行或使用我的Java代碼獲取內容，那麼它將無法正常工作：我無法連接到URL。

捲曲說：捲曲：（7）無法連接到主機

Java代碼如下：

private ICalendar getICalWithUrl(String url) throws Exception { 
    ICalendar iCal = null; 
    // Create an instance of HttpClient. 
    HttpClient client = new HttpClient(); 
    // Create a method instance. 
    GetMethod method = new GetMethod(url); 
    // Provide custom retry handler is necessary 
    method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler(3, false)); 
    try { 
     // Execute the method. 
     int statusCode = client.executeMethod(method); 
     if (statusCode != HttpStatus.SC_OK) { 
     throw new Exception("Unable to get content at the url "+url+". Method failed: " + method.getStatusLine()); 
     } 
     // Read the response body. 
     byte[] responseBody = method.getResponseBody(); 
     iCal=BiweeklyManager.parse(new String(responseBody)); 
    } finally { 
     // Release the connection. 
     method.releaseConnection(); 
    } 
    return iCal; 
}

而且堆棧跟蹤如下：

待辦事項你知道爲什麼我在這種情況下無法訪問網址，我能做些什麼來訪問它？

非常感謝您的回答:)

，準確的URL在捲曲對我的作品... –

您是否在企業環境？這聽起來像是一個代理設置問題，特別是考慮到你從瀏覽器訪問它。

與--proxy選項嘗試捲曲（見例如Linux curl command with proxy）
