在React Native中实现Apple登录与Parse集成

使用 apple 登录 react native 介绍 在上一个教程中，您使用 parse user parse user 类为您的应用程序构建了用户登录/注销功能。现在您将学习如何使用 apple 登录从 apple 检索用户数据并登录、注册或将现有用户与之关联。您还将安装和配置 react native apple authentication react native apple authentication 库来实现这一点。 parse user linkwith parse user linkwith 方法负责使用任何第三方身份验证方法注册和登录用户，只要您传递每个不同提供者所请求的正确参数。在将用户数据链接到新的或现有的 parse user parse user 后，parse 将在您的设备上存储有效的用户会话。未来对 currentasync currentasync 等方法的调用将成功检索您的用户数据，就像常规登录一样。 您可以随时访问我们 github 仓库中构建的完整 android 项目 https //github com/templates back4app/android parse sdk kotlin https //github com/templates back4app/android parse sdk java 前提条件 要完成本教程，您需要： 一个创建的 react native 应用，并且 https //www back4app com/docs/react native/parse sdk/react native sdk 完成之前的指南，以便更好地理解 https //www back4app com/docs/react native/parse sdk/working with users/react native login 目标 使用 apple 登录在 parse 上为 react native 应用构建用户登录功能。 1 安装依赖 在 react native 中启用 apple 登录的最流行方法是使用 react native apple authentication react native apple authentication 来处理它。由于该库的配置取决于您的开发环境、目标平台和偏好，请按照 https //github com/invertase/react native apple authentication 进行设置。 如果您正在为 android 开发，您还需要安装 https //github com/auth0/jwt decode 库来解码 apple jwt 令牌。 注意： 请确保彻底遵循 xcode 环境的初始设置说明，在 apple 开发者门户上创建您的应用 id、密钥和服务 id。 2 使用 apple 登录与 parse 现在让我们在 userlogin userlogin 组件中创建一个新方法，调用 apple 登录认证模态框。 react native apple authentication react native apple authentication 库有两个独立的模块来处理此调用，具体取决于您的用户平台，因此您需要在 ios 上使用 appleauth performrequest appleauth performrequest ，在 android 上使用 appleauthandroid signin appleauthandroid signin 。如果用户使用 apple 登录，此调用将从 apple 检索用户数据，您需要存储 id id , token token 和 apple 邮箱以备后用。 javascript 1 const douserloginapple = async function () promise\<boolean> { 2 try { 3 let response = {}; 4 let appleid = ''; 5 let appletoken = ''; 6 let appleemail = ''; 7 if (platform os === 'ios') { 8 // performs login request requesting user email 9 response = await appleauth performrequest({ 10 requestedoperation appleauth operation login, 11 requestedscopes \[appleauth scope email], 12 }); 13 // on ios, user id and email are easily retrieved from request 14 appleid = response user; 15 appletoken = response identitytoken; 16 appleemail = response email; 17 } else if (platform os === 'android') { 18 // configure the request 19 appleauthandroid configure({ 20 // the service id you registered with apple 21 clientid 'your service id', 22 // return url added to your apple dev console 23 redirecturi 'your redirect url', 24 responsetype appleauthandroid responsetype all, 25 scope appleauthandroid scope all, 26 }); 27 response = await appleauthandroid signin(); 28 // decode user id and email from token returned from apple, 29 // this is a common workaround for apple sign in via web api 30 const decodedidtoken = jwt decode(response id token); 31 appleid = decodedidtoken sub; 32 appletoken = response id token; 33 appleemail = decodedidtoken email; 34 } 35 // format authdata to provide correctly for apple linkwith on parse 36 const authdata = { 37 id appleid, 38 token appletoken, 39 }; 40 } catch (error) { 41 // error can be caused by wrong parameters or lack of internet connection 42 alert alert('error!', error); 43 return false; 44 } 45 };1 const douserloginapple = async function () promise\<boolean> { 2 try { 3 let response object = {}; 4 let appleid string = ''; 5 let appletoken string = ''; 6 let appleemail string = ''; 7 if (platform os === 'ios') { 8 // performs login request requesting user email 9 response = await appleauth performrequest({ 10 requestedoperation appleauth operation login, 11 requestedscopes \[appleauth scope email], 12 }); 13 // on ios, user id and email are easily retrieved from request 14 appleid = response user; 15 appletoken = response identitytoken; 16 appleemail = response email; 17 } else if (platform os === 'android') { 18 // configure the request 19 appleauthandroid configure({ 20 // the service id you registered with apple 21 clientid 'your service id', 22 // return url added to your apple dev console 23 redirecturi 'your service url', 24 responsetype appleauthandroid responsetype all, 25 scope appleauthandroid scope all, 26 }); 27 response = await appleauthandroid signin(); 28 // decode user id and email from token returned from apple, 29 // this is a common workaround for apple sign in via web api 30 const decodedidtoken object = jwt decode(response id token); 31 appleid = decodedidtoken sub; 32 appletoken = response id token; 33 appleemail = decodedidtoken email; 34 } 35 // format authdata to provide correctly for apple linkwith on parse 36 const authdata object = { 37 id appleid, 38 token appletoken, 39 }; 40 } catch (error any) { 41 // error can be caused by wrong parameters or lack of internet connection 42 alert alert('error!', error); 43 return false; 44 } 45 }; 请注意，对于android，您需要解码来自apple的返回令牌，因为该库 react native apple authentication react native apple authentication 使用apple sign in网页api进行身份验证。使用此方法时，数据访问存在限制，因此获取用户id和电子邮件的常见解决方法是通过此解码过程，如官方parse指南中所述 https //docs parseplatform org/parse server/guide/#apple authdata 。 之后，您可以使用 parse user linkwith parse user linkwith 在一个新的 parse user parse user 对象上注册新用户并登录。请注意，如果您的用户已经使用此 apple 认证注册， linkwith linkwith 将使用现有账户登录他。 javascript 1 const douserloginapple = async function () promise\<boolean> { 2 try { 3 let response = {};

71 return false; 72 } 73 }; 将此功能添加到您的 usersignin usersignin 组件，并将其分配给您的 apple 按钮 onpress onpress 参数。继续测试您的新功能。请注意，用户在成功注册和/或登录后将被重定向到您的主屏幕。 3 验证用户登录和会话创建 为了确保 apple 登录成功，您可以查看您的 parse 仪表板，查看您的新 用户 用户 （如果您的 apple 认证数据不属于其他用户），包含 apple authdata authdata 参数。 您还可以在仪表板中验证是否创建了有效的会话，其中包含指向该 用户 用户 对象的指针。 4 将现有用户链接到 apple 登录 另一个 linkwith linkwith 可能的用法是将现有用户与另一个身份验证提供者链接，在这种情况下是 apple。添加这个调用 linkwith linkwith 的功能，方法与您在 userlogin userlogin 中所做的相同，添加到您的 hellouser hellouser 组件或直接添加到您的主屏幕。这里唯一的区别是，您将从已登录的用户对象中使用它，而不是从空的 parse user parse user 调用该方法。 javascript 1 const douserlinkapple = async function (){ 2 try { 3 let response = {};
