### Signature Calculation Rules

Source: https://static-eu.xiaopeng.com/xp-ucenter/api-integration-guide-en-0.0.1.html

Details on how to construct the signature string and calculate the SHA1 hash for API requests.

```APIDOC
## Signature Calculation

### Description
All requests must include a `sign` parameter calculated using the following steps:

1. **Build stringA**: Exclude `appId` and `sign` from query parameters. Add the request body as a field with key `"body"`. Sort all keys (including `body`) in natural ascending order and concatenate as `key1+value1+key2+value2`.
2. **Build stringB**: Prepend `appId` and append `appSecret` to `stringA`.
3. **Calculate sign**: Compute the SHA1 hash of `stringB` and convert the result to lowercase.

### Example (stringB construction)
`stringB = ${appId} + stringA + ${appSecret}`

### Example (sign calculation)
`sign = SHA1(stringB).toLowerCase()`
```

--------------------------------

### Signature Generation for /oauth2/authorize

Source: https://static-eu.xiaopeng.com/xp-ucenter/api-integration-guide-en-0.0.1.html

Demonstrates the concatenation rules for building StringA, StringB, and the final SHA1 signature for the authorize endpoint.

```text
GET https://xxx.xpeng.com/open/oauth2/authorize?appId=APPID&nonce=NONCE&state=STATE&sign=SIGN

StringA = bodynonceNONCEstateSTATE
StringB = APPIDbodynonceNONCEstateSTATEAPPSECRET
sign    = SHA1(StringB).toLowerCase()
```
