我正在将我的项目从 Swift 2.3 迁移到 Swift 3。并且遇到了预期的困难。
这是一个用于 OAuth 的函数,使用 OAuthSwift .我试过转换
class func OAuthSwiftAuthorization(inViewController viewController: UIViewController, withOAuthInfo info:FitnessTracker, successHandler:@escaping MyOAuthNewSuccessHandler, failure: @escaping ((_ error: NSError) -> Void)) {
let oauthswift = OAuth2Swift(
consumerKey: info.consumerKey,
consumerSecret: info.consumerSecret,
authorizeUrl: info.authorizeUrl,
accessTokenUrl: info.accessTokenUrl,
responseType: info.responseType
)
oauthswift.authorizeURLHandler = SafariURLHandler(viewController: viewController, oauthSwift: oauthswift)
oauthswift.accessTokenBasicAuthentification = true
oauthswift.allowMissingStateCheck = true
oauthswift.authorize(withCallbackURL: URL(string: info.callBackUrl)!, scope: info.scope, state: info.state, success: { (credential, response, parameters) in
successHandler(credential, response, parameters)
}) { (error) in
failure(error: error)
print(error.localizedDescription)
}
}
但是我在
处遇到错误oauthswift.authorize(withCallbackURL: URL(string: info.callBackUrl)!, scope: info.scope, state: info.state, success: { (credential, response, parameters) in
错误状态
Ambiguous reference to member 'authorize(withCallbackURL:scope:state:parameters:headers:success:failure:)'
这是 Swift 2 的工作代码。
oauthswift.authorizeWithCallbackURL(
URL(string: info.callBackUrl)!,
scope: info.scope, state:info.state,
success: { credential, response, parameters in
successHandler(credientials: credential, response: response, params: parameters)
},
failure: { error in
failure(error: error)
print(error.localizedDescription)
}
)
更新:
错误不会出现,直到我输入成功和失败处理程序。这很好:
oauthswift.authorize(withCallbackURL: URL(string: info.callBackUrl)!, scope: info.scope, state: info.state, success: { (credential, response, parameters) in
// successHandler(credential, response, parameters)
}) { (erorr) in
// failure(error: error
}
所以请指导我谢谢。
最佳答案
我认为问题是Swift结合闭包的类型推断的一些不足造成的。 您可以尝试以下方法之一:
要么不使用尾随闭包,例如
oauthswift.authorize(withCallbackURL: URL(string: info.callBackUrl)!, scope: info.scope, state: info.state, success: { (credential, response, parameters) in
successHandler(credential, response, parameters)
}, failure: { (error) in
failure(error: error)
print(error.localizedDescription)
})
或者为错误提供明确的类型,例如
oauthswift.authorize(withCallbackURL: URL(string: info.callBackUrl)!, scope: info.scope, state: info.state, success: { (credential, response, parameters) in
successHandler(credential, response, parameters)
}) { (error: Error) in
failure(error: error)
print(error.localizedDescription)
}
