Question

我有以下curl命令在命令行上运行正常，但我无法在Swift中编写它。

 curl -u web:web -k -i -d '{ "email":"fb@test.com","fbId":"FBXXXFB","accessToken":"accessNow","familyName":"FamName","givenName":"given"}' -H "Content-Type: application/json;charset=UTF-8" -X POST 'https://xweb.test.herokuapp.com/olweb/auth/login/fb'

当我尝试在Alamofire中翻译时，我总是从服务器收到错误。所以我假设auth工作正常，但参数不正确，因为我需要向服务器发送5个参数。我怎么能这样做呢？

以下是代码段：

func loginWithFacebook(loginEmail: String, facebookId: String,  accessToken: String,familyName: String, givenName: String, completionHandler: (AnyObject?, NSError?) -> ()) {

    //Basic HTTP auth
    let user = "web"
    let password = "web"

    //   let headers = ["Authorization": "Basic \(base64Credentials)"] not working
    //   let headers =  ["web": "web"] not working

    //example for a nested array query
    let parameters = [
            "loginEmail": loginEmail,
            "facebookId": facebookId,
            "accessToken": accessToken,
            "familyName": familyName,
            "givenName": givenName
    ]

    Alamofire.request(
        .POST,
        loginWithFacebook,
        parameters: parameters
        )
        .responseJSON { response in
            switch response.result {
            case .Success(let value):
                completionHandler(value, nil)
            case .Failure(let error):
                completionHandler(nil, error)
            }
        }
        .authenticate(user: user, password: password)
}

我用以下方式调用此方法：

self.restApi.loginWithFacebook(email, facebookId: facebookId, accessToken: accessToken, familyName: familyName, givenName: firstName) {responseObject, error in

        print("responseobject printed loginUserWithFacebook() ")
        print(responseObject)
        print("error printed")
        print(error)

        //get the JSON object
        let response = responseObject as? [String:AnyObject]
        print("response")
        print(response)

        //parse down the first layer of JSON object which is an NSDictionary (sometimes it is [AnyObject] )
        if let result = response!["result"]  as?  [String: AnyObject]
        {
            print("self.result.count after calling loginUserWithFacebook()")
            print(result.count)
            print(result)

          //  self.getProfileFromUser()
        }
    }

来自服务器的错误响应：

responseobject printed loginUserWithFacebook() 
Optional({
info = "Required fields missing.";
result =     {
};
})

在你的cURL请求中，正文是JSON。但是，您的Alamofire代码将使用URL编码的参数发送请求。请尝试使用JSON：

Alamofire.request(
    .POST,
    loginWithFacebook,
    parameters: parameters,
    encoding: .JSON
    )

另请注意，您的cURL请求使用了密钥email和fbId，但您的Alamofire代码使用loginEmail和facebookId。如果您的服务器不支持这两者，您可能还需要更改它们。
