# HTTP download

HTTP Download是一个高级操作，用于直接从在线路径（URL）下载文件（如图像、视频、文档文件、zip文件等）到您的计算机上，而无需打开浏览器手动点击下载按钮。

#### 配置参数：

* URL：指向要下载的文件的在线路径地址（例如：`https://example.com/images/avatar.jpg`）。
* Save Path：您希望在计算机上保存下载文件的绝对路径，包括文件名和格式后缀（例如：`D:\GPM_Data\downloads\avatar.jpg`）。
* Headers：附加信息，随请求发送以验证访问权限或模拟浏览器，如果服务器要求（例如：`User-Agent: Mozilla/5.0...`或`Authorization: Bearer $token`）。如果下载公共文件，您可以将此项留空。
* Output variable：保存操作返回结果的变量名称（通常返回逻辑值`True`，如果文件下载成功，或系统的响应日志内容）。

#### 实际示例：自动将视频从可用路径下载到计算机

假设您正在运行一个抓取文章的脚本，系统已经提取出一个视频的在线路径并存储在变量`$videoUrl`中。您希望将此视频下载到D盘的一个固定文件夹中，以便为后续处理步骤做准备：

* 配置方法：
  * URL：将变量`$videoUrl`传递到输入框中。
  * Save Path：填写具体的文件保存路径，例如：`D:\GPM_Data\Videos\downloaded_video.mp4`。
  * Headers：留空（如果下载链接是公共的，不需要账户）。
  * Output variable：将保存结果的变量命名为`downloadStatus`。

结果：系统将自动连接网络，从路径`$videoUrl`下载视频文件，并生成一个名为`downloaded_video.mp4`的物理文件，整齐地位于`D:\GPM_Data\Videos\`文件夹中。变量`$downloadStatus`将接收值，以便您可以使用If语句块检查文件是否成功下载，然后再进行后续操作。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.gpmautomate.com/automate-zh/cao-zuo-zhi-nan/http/http-download.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
