# Rust (/zh/quickstarts/rust)
## 前置条件 [#前置条件]
* Rust 1.70+，并已安装 Cargo
* 一个 Firecrawl API 密钥——[免费获取](https://www.firecrawl.dev/app/api-keys)
## 安装 crate [#安装-crate]
将 `firecrawl` 添加到 `Cargo.toml` 中：
```toml
[dependencies]
firecrawl = "2"
tokio = { version = "1", features = ["full"] }
serde_json = "1"
```
## 进行网页搜索 [#进行网页搜索]
```rust
use firecrawl::{Client, SearchOptions};
#[tokio::main]
async fn main() -> Result<(), Box> {
let client = Client::new("fc-YOUR-API-KEY")?;
let results = client.search(
"firecrawl web scraping",
SearchOptions { limit: Some(5), ..Default::default() },
).await?;
if let Some(web) = results.data.web {
for item in web {
if let firecrawl::SearchResultOrDocument::WebResult(r) = item {
println!("{} - {}", r.url, r.title.unwrap_or_default());
}
}
}
Ok(())
}
```
## 抓取网页 [#抓取网页]
```rust
let doc = client.scrape("https://example.com", None).await?;
println!("{}", doc.markdown.unwrap_or_default());
```
```json
{
"markdown": "# Example Domain\n\nThis domain is for use in illustrative examples...",
"metadata": {
"title": "Example Domain",
"sourceURL": "https://example.com"
}
}
```
## 与页面交互 [#与页面交互]
先抓取网页以获取 `scrapeId`，然后使用交互 API 控制浏览器会话：
```rust
use firecrawl::{Client, ScrapeOptions, Format, ScrapeExecuteOptions};
let doc = client.scrape(
"https://www.amazon.com",
ScrapeOptions {
formats: Some(vec![Format::Markdown]),
..Default::default()
},
).await?;
let scrape_id = doc.metadata
.as_ref()
.and_then(|m| m.scrape_id.as_deref())
.expect("scrapeId not found");
// 发送 prompt 与页面交互
let run = client.interact(
scrape_id,
ScrapeExecuteOptions {
prompt: Some("Search for iPhone 16 Pro Max".to_string()),
..Default::default()
},
).await?;
let run = client.interact(
scrape_id,
ScrapeExecuteOptions {
prompt: Some("Click on the first result and tell me the price".to_string()),
..Default::default()
},
).await?;
println!("{:?}", run.output);
// 关闭会话
client.stop_interaction(scrape_id).await?;
```
## 环境变量 [#环境变量]
设置 `FIRECRAWL_API_KEY`，不要直接传入 API 密钥：
```bash
export FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```
```rust
let api_key = std::env::var("FIRECRAWL_API_KEY")?;
let client = Client::new(api_key)?;
```
## 后续步骤 [#后续步骤]
进行网页搜索并获取完整页面内容
包含所有 抓取 选项，包括 formats、actions 和代理
点击、填写表单并提取动态内容
完整的 SDK 参考，包含爬取、map、batch scrape 等功能
