iOS第三方授权（Apple/Google/Facebook）接入Supabase方法咨询

你已经完成Apple登录的对接，下面针对Google和Facebook的凭证交换流程给出具体实现步骤：

Google登录对接 #

1. 请求端点：https://SUPABASE_ID.supabase.co/auth/v1/token
2. 请求方式：POST
3. 请求头：设置Content-Type: application/json
4. 请求参数：
   • grant_type: id_token
   • provider: google
   • id_token: 从GoogleSignIn框架获取到的idToken字符串
5. 示例Swift请求代码：

import Foundation

func exchangeGoogleTokenForSupabaseSession(googleIdToken: String) async throws -> Data {
    let supabaseUrl = URL(string: "https://SUPABASE_ID.supabase.co/auth/v1/token")!
    var request = URLRequest(url: supabaseUrl)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    
    let parameters: [String: Any] = [
        "grant_type": "id_token",
        "provider": "google",
        "id_token": googleIdToken
    ]
    request.httpBody = try JSONSerialization.data(withJSONObject: parameters)
    
    let (data, response) = try await URLSession.shared.data(for: request)
    
    // 处理响应：解析data获取Supabase的access_token、refresh_token等会话信息
    guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 else {
        throw NSError(domain: "SupabaseAuth", code: -1, userInfo: [NSLocalizedDescriptionKey: "Token exchange failed"])
    }
    return data
}

Facebook登录对接 #

1. 请求端点：https://SUPABASE_ID.supabase.co/auth/v1/token
2. 请求方式：POST
3. 请求头：设置Content-Type: application/json
4. 请求参数：
   • grant_type: convert_token
   • provider: facebook
   • access_token: 从FBSDKLoginKit框架获取到的accessToken字符串
5. 示例Swift请求代码：

import Foundation

func exchangeFacebookTokenForSupabaseSession(facebookAccessToken: String) async throws -> Data {
    let supabaseUrl = URL(string: "https://SUPABASE_ID.supabase.co/auth/v1/token")!
    var request = URLRequest(url: supabaseUrl)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    
    let parameters: [String: Any] = [
        "grant_type": "convert_token",
        "provider": "facebook",
        "access_token": facebookAccessToken
    ]
    request.httpBody = try JSONSerialization.data(withJSONObject: parameters)
    
    let (data, response) = try await URLSession.shared.data(for: request)
    
    // 处理响应：解析data获取Supabase的会话凭证
    guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 else {
        throw NSError(domain: "SupabaseAuth", code: -1, userInfo: [NSLocalizedDescriptionKey: "Token exchange failed"])
    }
    return data
}

通用注意事项 #

• 替换请求URL中的SUPABASE_ID为你的Supabase项目ID
• 成功响应会包含access_token、refresh_token和expires_in等字段，后续调用Supabase服务时需携带access_token作为授权凭证
• 建议处理网络请求的异常情况（如无网络、HTTP错误码等）
