Swift PKPass eror 'The pass cannot be read because it isn’t valid'

Question

我正在从服务器创建一个Ticket，并将其传递到我的ios应用程序中，但当我试图将JSON数据传递到PKPass模型中时，我一直会收到这个错误。

Error Domain=PKPassKitErrorDomain Code=1 "The pass cannot be read because it isn’t valid.

在我的服务器上，它说票证创建成功，但我在Xcode中仍然收到这个错误。我把数据解码错了吗？如何使用JSON响应创建PKPass？

服务器端代码：

exports.createTicket = functions.https.onRequest(async (req, res) => {
const passName = "Event"
try {
const examplePass = await createPass({
model: "./models/Event",
certificates: {
wwdr: "./models/certs/wwdrc.pem",
signerCert: "./models/certs/signerCert.pem",
signerKey: {
keyFile: "./models/certs/signerKey.pem",
passphrase: "54321"
}
},
overrides: {
// keys to be added or overridden
serialNumber: "AAGH44625236dddaffbda"
}
});
examplePass.barcode("36478105430"); // Random value
// Generate the stream, which gets returned through a Promise
const stream = examplePass.generate();
res.set({
"Content-Type": "application/vnd.apple.pkpass",
"Content-disposition": `attachment; filename=${passName}.pkpass`
});
stream.pipe(res);
console.log("Successfully created ticket", stream)
} catch (err) {
console.log("There was an error", err)
res.set({
"Content-type": "text/html",
});
res.send(err.message);
}
});

IOS侧：

AF.request(URLString, method: .post, parameters: requestData).responseString { response in
guard let data = response.data as? Data else { return }
do {
let pass = try PKPass(data: data)
print(pass)
} catch {
print("Error", error)
}

}

pass.json

{
"formatVersion": 1,
"passTypeIdentifier": "pass.com.CodyHost.Finder-Dev",
"teamIdentifier": "L9C6U8UKPB",
"organizationName": "Finder",
"description": "Rolling loud new york 2020",
"eventTicket": {}
}

Answer 1

查看您的签名和pass.json，您的pass无法加载，因为用于创建签名的证书是：

• PassTypeId:pass.com.apple.devpubs.example
• 队名：A93A5CM278

这与pass.json中的passTypeIdentifier和teamName不匹配。

将./models/certs/signerCert.pem和./models/certs/signerKey.pem替换为PassTypeId证书的正确证书和密钥，您应该可以克服此错误。

使用上面的pass.json编译的任何过程仍然不会加载，但原因不同。eventTicket对象不能为空。
