推荐答案
这是获取最新下载的文件名和URL的简单解决方案.
Here is the simple solution to get the latest downloaded file name and url.
注意:在运行下面的代码之前，请考虑文件下载已完成.
如果您要脚本等到下载完成，请在答案末尾检查 getDownLoadedFileName 方法.
If you want the script wait until the download completed, then check the getDownLoadedFileName method at the end of the answer.
# open a new tab
driver.execute_script("window.open()")
# switch to new tab
driver.switch_to.window(driver.window_handles[-1])
# navigate to chrome downloads
driver.get('chrome://downloads')
# get the latest downloaded file name
fileName = driver.execute_script("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').text")
# get the latest downloaded file url
sourceURL = driver.execute_script("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').href")
# print the details
print(fileName)
print (sourceURL)
# close the downloads tab2
driver.close()
# switch back to main window
driver.switch_to.window(driver.window_handles[0])
如果需要，可以将其作为方法并在需要的地方调用.
if you want you can make it as a method and call where ever it's required.
不必担心，直到下载完成
您可以中继chrome下载状态，请检查以下方法.
You can relay on chrome downloads status, check the below method.
只需在代码中调用以下方法，同时获取文件名
Just call the below method in you code while getting the file name
def getDownLoadedFileName(waitTime):
downloadsList = driver.execute_script("return document.querySelector('downloads-manager').shadowRoot")
endTime = time.time()+waitTime
while True:
try:
fileName = driver.execute_script("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').text")
if fileName:
return fileName
except:
pass
time.sleep(1)
if time.time() > endTime:
break
您可以按如下所示调用此方法.
You can call this method as shown below.
# wait until the download completes and get the file name
fileName = getDownLoadedFileName(180)
print(fileName)
Firefox :将以下方法用于Firefox.
Firefox: Use the below method for firefox.
def getDownLoadedFileName(waitTime):
driver.execute_script("window.open()")
WebDriverWait(driver,10).until(EC.new_window_is_opened)
driver.switch_to.window(driver.window_handles[-1])
driver.get("about:downloads")
endTime = time.time()+waitTime
while True:
try:
fileName = driver.execute_script("return document.querySelector('#contentAreaDownloadsView .downloadMainArea .downloadContainer description:nth-of-type(1)').value")
if fileName:
return fileName
except:
pass
time.sleep(1)
if time.time() > endTime:
break
Java + Chrome::如果您正在寻找Java实现.
Java + Chrome: In case if you are looking for java implementation.
这是Java中的方法.
Here is the method in java.
public String waitUntilDonwloadCompleted(WebDriver driver) throws InterruptedException {
// Store the current window handle
String mainWindow = driver.getWindowHandle();
// open a new tab
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("window.open()");
// switch to new tab
// Switch to new window opened
for(String winHandle : driver.getWindowHandles()){
driver.switchTo().window(winHandle);
}
// navigate to chrome downloads
driver.get("chrome://downloads");
JavascriptExecutor js1 = (JavascriptExecutor)driver;
// wait until the file is downloaded
Long percentage = (long) 0;
while ( percentage!= 100) {
try {
percentage = (Long) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('#progress').value");
//System.out.println(percentage);
}catch (Exception e) {
// Nothing to do just wait
}
Thread.sleep(1000);
}
// get the latest downloaded file name
String fileName = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').text");
// get the latest downloaded file url
String sourceURL = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').href");
// file downloaded location
String donwloadedAt = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div.is-active.focus-row-active #file-icon-wrapper img').src");
System.out.println("Download deatils");
System.out.println("File Name :-" + fileName);
System.out.println("Donwloaded path :- " + donwloadedAt);
System.out.println("Downloaded from url :- " + sourceURL);
// print the details
System.out.println(fileName);
System.out.println(sourceURL);
// close the downloads tab2
driver.close();
// switch back to main window
driver.switchTo().window(mainWindow);
return fileName;
}
这是在Java脚本中调用它的方法.
This is how to call this in your java script.
// download triggering step
downloadExe.click();
// now waituntil download finish and then get file name
System.out.println(waitUntilDonwloadCompleted(driver));
