支付宝api文档: https://opendocs.alipay.com/apis/
签名方法为 RSA2,采用支付宝提供的 RSA签名&验签工具 生成秘钥时,秘钥的格式必须为 PKCS1(现如今生成的秘钥可能不是PKCS1,需要先通过秘钥工具转换一下),秘钥长度推荐 2048。所以在支付宝管理后台请注意配置 RSA2(SHA256)密钥。
这是一个简单的alipay SDK,只需要创建client,然后通过client的post方法请求Alipay api即可。
```toml
[dependencies] alipay-rs = "0.4"
```
以单笔转账接口为例:
```rust
...
// 接口参数 // 参数调用需要使用AlipayParams宏
struct Transfer { outbizno: String, transamount: String, productcode: String, bizscene: String, payeeinfo: PayeeInfo, }
struct PayeeInfo { identity: String, identity_type: String, name: String, }
async fn fundtransfer() { let transfer = Transfer { outbizno: format!("{}", Local::now().timestamp()), transamount: String::from("0.1"), productcode: String::from("TRANSACCOUNTNOPWD"), bizscene: String::from("DIRECTTRANSFER"), payeeinfo: PayeeInfo { identity: String::from("343938938@qq.com"), identitytype: String::from("ALIPAYLOGONID"), name: String::from("陈怀远"), }, }; let client = alipayrs::Client::builder() .appid("20210xxxxxxxxxxx") .publickey(includestr!("../公钥.txt")) .privatekey(includestr!("../私钥.txt")) .appcertsn(includestr!("../appCertPublicKey20210xxxxxxxxxxx.crt")) .alipayrootcertsn(includestr!("../alipayRootCert.crt")) .finish(); let data:serdejson::Value = client .post("alipay.fund.trans.uni.transfer", transfer) .await.unwrap().intojson().unwrap(); println!("{:?}", data); } ```
支付宝的所有接口都可以使用client.post函数访问,如果接口没有参数,可以使用client.noparampost函数。 默认的公共参数包含:appid,charset,signtype,format,version,method,timestamp,sign,如果想修改或添加参数值,可以通过client.setpublicparams函数设置。
```rust
...
// 可以通过AlipayParams宏来定义需要添加或修改的公共参数
struct PublicParams { appid: String, charset: String, signtype: String, version: String, }
...
let publicparams = PublicParams { appid: "20210xxxxxxxxxxx".toowned(), charset: "utf-8".toowned(), signtype: "RSA2".toowned(), version: "1.0".to_owned(), };
// 也可以通过vec, hashmap, array, tuple来设置公共参数 let publicparams = ("appid", "20210xxxxxxxxxxx"); let publicparams = [("imagetype", "png"), ("imagename", "test")]; let publicparams = vec![("imagetype", "png"), ("imagename", "test")]; let publicparams = HashMap::from([("imagetype", "png"), ("image_name", "test")]);
let mut clientwithparams = client.setpublicparams(public_params);
...
```
alipay api有图片视频等资源上传的接口,可以通过post_file接口进行资源上传
```rust
struct Image { imagetype: String, imagename: String, } let file = std::fs::read("./test.png").unwrap(); let image = Image { imagetype: "png".toowned(), imagename: "test".toowned(), }; let client = ...; let mut clientwithparams = client.setpublicparams(image); // postfile参数: // method 接口名称 // key 文件参数名 // filename 文件名 // filecontent 文件内容 let data:serdejson::Value = clientwithparams.postfile("alipay.offline.material.image.upload", "imagecontent", "test.png", file.asref()).await.unwrap().intojson().unwrap(); println!("{:?}", data); ```
```rust
......
async fn refquery(client: &alipayrs::Client) { let query = QueryParam { operation: "ITEMPAGEQUERY".toowned(), pagenum: 1, pagesize: 10, itemidlist: None, };
let data:serde_json::Value = client
.post("alipay.open.mini.item.page.query", query)
.await.unwrap().into_json().unwrap();
println!("{:?}", data);
}
async fn reffundtransfer(client: &alipayrs::Client) { let transfer = Transfer { outbizno: format!("{}", Local::now().timestamp()), transamount: String::from("0.1"), productcode: String::from("TRANSACCOUNTNOPWD"), bizscene: String::from("DIRECTTRANSFER"), payeeinfo: PayeeInfo { identity: String::from("343938938@qq.com"), identitytype: String::from("ALIPAYLOGONID"), name: String::from("陈怀远"), }, }; let data:serdejson::Value = client .post("alipay.fund.trans.uni.transfer", transfer) .await.unwrap().intojson().unwrap(); println!("{:?}", data); }
......
let client = alipayrs::Client::builder() .appid("20210xxxxxxxxxxx") .publickey(includestr!("../公钥.txt")) .privatekey(includestr!("../私钥.txt")) .appcertsn(includestr!("../appCertPublicKey20210xxxxxxxxxxx.crt")) .alipayrootcertsn(includestr!("../alipayRootCert.crt")) .finish();
let cli = Arc::new(client); let cliclone = cli.clone(); tokio::spawn(async move { refquery(&cliclone).await; }).await.unwrap(); tokio::spawn(async move { reffund_transfer(&cli.clone()).await; }).await.unwrap(); ```
