# 文件上传

URL: https://deploy-preview-2977--selenium-dev.netlify.app/zh-cn/documentation/webdriver/elements/file_upload/

由于 Selenium 不能与文件上传对话框交互，因此它提供了一种无需打开对话框即可上传文件的方法。
如果该元素是一个类型为 `file` 的 `input` 元素，则可以使用
send keys 方法发送将要上传文件的完整路径。

**Java**

```java
WebElement fileInput = driver.findElement(By.cssSelector("input[type=file]"));
fileInput.sendKeys(uploadFile.getAbsolutePath());
driver.findElement(By.id("file-submit")).click();
```

**Python**

```python
file_input = driver.find_element(By.CSS_SELECTOR, "input[type='file']")
file_input.send_keys(upload_file)
driver.find_element(By.ID, "file-submit").click()
```

**CSharp**

```csharp
IWebElement fileInput = driver.FindElement(By.CssSelector("input[type=file]"));
fileInput.SendKeys(uploadFile);
driver.FindElement(By.Id("file-submit")).Click();
```

**Ruby**

```ruby
file_input = driver.find_element(css: 'input[type=file]')
file_input.send_keys(upload_file)
driver.find_element(id: 'file-submit').click
```

**JavaScript**

```javascript
await driver.get('https://the-internet.herokuapp.com/upload');
// Upload snapshot
```

**Kotlin**

    driver.get("https://the-internet.herokuapp.com/upload")
    driver.findElement(By.id("file-upload")).sendKeys("selenium-snapshot.jpg")
    driver.findElement(By.id("file-submit")).submit()
    if(driver.pageSource.contains("File Uploaded!")) {
        println("file uploaded")
    }

        println("file not uploaded")
    }
}
