Question

无论如何，我可以使用selenium获取最后下载的文件。目前我正在使用selenium下载Excel文件，我需要获取该文件并阅读它。阅读部分已被覆盖，但我需要下载的文件路径和文件名才能阅读。到目前为止，我还没有发现任何有用的东西。我主要是寻找一个谷歌Chrome解决方案，但firefox也可以。

提前致谢

Answer 1

您可以使用配置文件将下载内容保存到修复位置。检查这些讨论：

Downloading file to specified location with Selenium and python
Access to file download dialog in Firefox

如你所说，你已经覆盖了阅读部分。你可以从那个固定的位置阅读它。

以下是有助于解决上述问题的代码段：

**Changes in driver file:**

protected File downloadsDir = new File("");
if (browser.equalsIgnoreCase("firefox")) 
{
    downloadsDir = new File(System.getProperty("user.dir") + File.separatorChar + "downloads");
    if (!downloadsDir.exists()) 
     {
        boolean ddCreated = downloadsDir.mkdir();
        if (!ddCreated) {
            System.exit(1);
        }
    }
}


/*Firefox browser profile*/
FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("browser.download.folderList", 2);
firefoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
firefoxProfile.setPreference("browser.download.dir", downloadsDir.getAbsolutePath());
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk", "text/plain,application/octet-stream");

**Empty the download directory[Can be implemented as @BeforeClass]:**

public void emptyDownloadsDir()
{
    // Verify downloads dir is empty, if not remove all files.
    File[] downloadDirFiles = downloadsDir.listFiles();
    if (downloadDirFiles != null) {
        for (File f : downloadDirFiles) {
            if (f.exists()) {
                boolean deleted = FileUtility.delete(f);
                assertTrue(deleted, "Files are not deleted from system local directory" + downloadsDir + ", skipping the download tests.");
            }
        }
    }
}


**Check the Latest downloaded file:**

/*Test file*/
protected static String EXCEL_FILE_NAME= Test_Excel_File.xls;

protected static int WAIT_IN_SECONDS_DOWNLOAD = 60;

// Wait for File download.
int counter = 0;
while (counter++ < WAIT_IN_SECONDS_DOWNLOAD && (downloadsDir.listFiles().length != 1 || downloadsDir.listFiles()[0].getName().matches(EXCEL_FILE_NAME))) {
    this.wait(2);
}

// Verify the downloaded File by comparing name.
File[] downloadDirFiles = downloadsDir.listFiles();
String actualName = null;
for (File file : downloadDirFiles) {
    actualName = file.getName();
    if (actualName.equals(EXCEL_FILE_NAME)) {
        break;
    }
}
assertEquals(actualName, EXCEL_FILE_NAME, "Last Downloaded File name does not matches.");

Answer 3

import os
import glob

home = os.path.expanduser("~")
downloadspath=os.path.join(home, "Downloads")
list_of_files = glob.glob(downloadspath+"\*.pptx") # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getctime)

简化的解决方案，可获取“下载”文件夹中最后一个文件的路径。上面的代码将获取Downlodas中最新.pptx文件的路径。根据需要更改扩展名。否则，您可以选择不指定扩展名
