# twapi-v2-rs

Twitter API v2 library.

[Documentation](https://docs.rs/twapi-v2)

- Request builder
- Retrive response headers
- Convenience setted parameter methods
- Bearer authentication(OAuth 2.0 Authorization Code Flow with PKCE)
- OAuth1.0a authentication(OAuth 1.0a User Contex)
- Upload Media upload.twitter.com APIs
- Upload Media v2 (However, when I executed it, I got a 403 and was not successful.)
- Optional retriable and timeout and logging
- Optional OAuth with web example
- Optional v1 to v2 parser
- Streaming example
- Supported mocks. For example, mockito.
- Type support.

## Examples

### API(bearer)
```rust
use twapi_v2::api::{get_2_tweets_id, BearerAuthentication};

#[tokio::main]
async fn main() {
    let bearer_code = std::env::var("BEARER_CODE").unwrap();
    let auth = BearerAuthentication::new(bearer_code);
    let tweet_id = std::env::var("TWEET_ID").unwrap();
    let res = get_2_tweets_id::Api::open(&tweet_id)
        .execute(&auth)
        .await;
    if let Some((val, headers)) = res {
        println!("{:?}", val);
        println!("{}", headers);
    }
}
```

### API(OAuth1.0a)
```rust
use twapi_v2::api::{get_2_tweets_id, BearerAuthentication};
use twapi_v2::oauth10a::OAuthAuthentication;

#[tokio::main]
async fn main() {
    let auth = OAuthAuthentication::new(
        std::env::var("CONSUMER_KEY").unwrap_or_default(),
        std::env::var("CONSUMER_SECRET").unwrap_or_default(),
        std::env::var("ACCESS_KEY").unwrap_or_default(),
        std::env::var("ACCESS_SECRET").unwrap_or_default(),
    );
    let tweet_id = std::env::var("TWEET_ID").unwrap();
    let res = get_2_tweets_id::Api::open(&tweet_id)
        .execute(&auth)
        .await;
    if let Some((val, headers)) = res {
        println!("{:?}", val);
        println!("{}", headers);
    }
}
```

### V1 parse
```rust
use std::{fs::File, io::{Read, Write}};
use twapi_v2::models::TweetModel;

#[tokio::main]
async fn main() {
    let mut file = File::open("samples/v1_tweet.json").unwrap();
    let mut data = String::new();
    file.read_to_string(&mut data).unwrap();
    let src = serde_json::from_str::<serde_json::Value>(&data).unwrap();
    let res = TweetModel::from_v1(&src);
    let mut file = File::create("result.json").unwrap();
    write!(file, "{}", serde_json::to_string_pretty(&res).unwrap()).unwrap();
    file.flush().unwrap();
}
```

### Upload Media(v2)
```
cd examples/post-media
CONSUMER_KEY=xxx \
CONSUMER_SECRET=xxx \
ACCESS_KEY=xxx \
ACCESS_SECRET=xxx \
cargo run
```

### Twitter OAuth Web
```
cd examples/oauth-web
API_KEY_CODE=XXXX API_SECRET_CODE=XXXX CALLBACK_URL=http://localhost:3000/oauth cargo run
```
http://localhost:3000/

### Streaming
```
cd examples/streaming
BEARER_CODE=XXXXX cargo run
```

### Mock(Use mockito)
```rust
#[tokio::test]
async fn test_mock_get_2_tweets_search_recent_oauth() -> Result<()> {
    // Setup mock server
    let mut server = Server::new_async().await;
    let mock = server
        .mock("GET", "/2/tweets/search/recent")
        .match_query(mockito::Matcher::Any)
        .with_status(200)
        .with_header("content-type", "application/json")
        .with_body("{ \"origin\": \"0.0.0.0\" }")
        .create_async()
        .await;

    // Setup OAuth
    let auth = OAuthAuthentication::new(
        std::env::var("CONSUMER_KEY").unwrap_or_default(),
        std::env::var("CONSUMER_SECRET").unwrap_or_default(),
        std::env::var("ACCESS_KEY").unwrap_or_default(),
        std::env::var("ACCESS_SECRET").unwrap_or_default(),
    );

    // Setup prefix all APIs
    api::setup_prefix_url(&server.url());
    let builder = get_2_tweets_search_recent::Api::open("東京")
        .max_results(10)
        .build(&auth);
    let (res, _headers) = execute_twitter::<get_2_tweets_search_recent::Response>(builder).await?;
    assert_eq!(res.extra.get("origin"), Some(&json!("0.0.0.0")));
    mock.assert();

    // Clear prefix url
    api::clear_prefix_url();
    // Override prefix url
    let twapi_options = TwapiOptions {
        prefix_url: Some(server.url().clone())
    };
    let builder = get_2_tweets_search_recent::Api::open("東京")
        .max_results(10)
        .twapi_options(Some(twapi_options))
        .build(&auth);
    let (res, _headers) = execute_twitter::<get_2_tweets_search_recent::Response>(builder).await?;
    assert_eq!(res.extra.get("origin"), Some(&json!("0.0.0.0")));

    Ok(())
}
