swift - 带有 CRUD/Rest 的 Alamofire POST 参数

Question

我想使用 CRUD 示例作为基础向 Alamofire 请求添加一些 POST 参数。我无法发送我的参数。

enum Router: URLRequestConvertible {

static var baseURLString: String = NSUserDefaults.standardUserDefaults().objectForKey("url") as String!

case GetForms()
case Login(String, String)

var method: Alamofire.Method {
    switch self {
    case .GetForms:
        return .GET
    case .Login:
        return .POST
    default:
        return .GET
    }
}

var path: String {
    switch self {
    case .GetForms():
        return "getforms"
    case .Login(let email, let password):
        return "login"
    default:
        return ""
    }
}

var URLRequest: NSURLRequest {
    let URL = NSURL(string: Router.baseURLString)!
    let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))

    switch self {
    case .GetForms():
        let token: String = NSUserDefaults.standardUserDefaults().objectForKey("apikey") as String!
        mutableURLRequest.HTTPMethod = method.rawValue
        mutableURLRequest.setValue(token, forHTTPHeaderField: "Authorization")
        return mutableURLRequest
    case .Login(_, let parameters):

// HERE I WANT TO ADD THE 2 POST Paramers from the Login Function

        return mutableURLRequest
    default:
        return mutableURLRequest
    }

}
}

但这行不通。我会尝试更改示例代码，但我真的不明白如何添加简单的 2 个 Post 参数。它应该像我将它用作简单请求时一样。喜欢:

Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["email": "admin", "password": "password"])
     .response { (_, _, _, error) in
              println(error)
     }

如有任何帮助，我们将不胜感激!

您可以通过在 Alamofire ParameterEncoding 实例上调用 encode 方法，将参数应用于您的 mutableURLRequest。如果是标准的 POST 请求，您需要使用 URL 大小写:

switch self {
case .GetForms():
    // ...

case .Login(let email, let password):
    // do any URL request setup first
    mutableURLRequest.HTTPMethod = method.rawValue

    // set up parameters
    let parameters = ["email": email, "password": password]

    // return first element of tuple from encode
    return ParameterEncoding.URL.encode(mutableURLRequest, parameters).0

default:
    return mutableURLRequest
}
