Alamofire：使用字典数组发送JSON [英] Alamofire: Send JSON with Array of Dictionaries

问题描述

我有一个类似JSON的数据结构：

I have a data structure that looks like this in JSON:

[{
    "value": "1",
    "optionId": "be69fa23-6eca-4e1b-8c78-c01daaa43c88"
}, {
    "value": "0",
    "optionId": "f75da6a9-a34c-4ff6-8070-0d27792073df"
}]

基本上它是一个数组的字典。我宁愿使用默认的Alamofire方法，也不想手动构建请求。有没有办法给Alamofire提供我的参数，其余的由Alamofire承担？

Basically it is an array of dictionaries. I would prefer to use the default Alamofire methods and would not like to build the request manually. Is there a way to give Alamofire my parameters and Alamofire does the rest?

如果我手动创建所有内容，则会从服务器收到错误消息，提示发送数据不会正确。

If I create everything by hand I get an error from the server that the send data would not be correct.

    var parameters = [[String:AnyObject]]()

    for votingOption in votingOptions{

        let type = votingOption.votingHeaders.first?.type

        let parameter = ["optionId":votingOption.optionID,
            "value": votingOption.votingBoolValue
        ]
        parameters.append(parameter)
    }

    let jsonData = try! NSJSONSerialization.dataWithJSONObject(parameters, options: [])
    let json = try! NSJSONSerialization.JSONObjectWithData(jsonData, options: .AllowFragments)


    if let url = NSURL(string:"myprivateurl"){
        let request = NSMutableURLRequest(URL: url)
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        request.HTTPMethod = Method.POST.rawValue
        request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(parameters, options: [])

        AlamofireManager.Configured.request(request)
            .responseJSON { response in
           //Handle result     
        }
    }

推荐答案

您可以执行以下操作：

You can do something like this:

Alamofire.request(.POST, urlPath, parameters: params).responseJSON{ request, response, data in
    //YOUR_CODE
}

其中参数是 [String：AnyObject] ，是的，Alamofire负责其余部分。

Where parameters is [String:AnyObject] and yes Alamofire takes care of the rest.

因为看起来像您正在使用管理员，您可以执行此操作

Since it looks like you are using a manager you can do this

YOUR_ALAMOFIRE_MANAGER.request(.POST, url, parameters: params).responseJSON{ request, response, JSON in
   //enter code here
}

源代码：

public func request(
    method: Method,
    _ URLString: URLStringConvertible,
    parameters: [String: AnyObject]? = nil,
    encoding: ParameterEncoding = .URL,
    headers: [String: String]? = nil)
    -> Request
{
    let mutableURLRequest = URLRequest(method, URLString, headers: headers)
    let encodedURLRequest = encoding.encode(mutableURLRequest, parameters: parameters).0
    return request(encodedURLRequest)
}

编辑：

由于您的数据当前为 [[String：AnyObject]] ，因此您需要对其进行修改，使其形式为 [String：AnyObject] 。您可以通过执行 [ data：[[String：AnyObject]]] 的一种方式来实现。不过，您可能必须更改api端点。

Since your data is currently [[String:AnyObject]] you will need to modify it so it is in the form [String:AnyObject]. One way you could do this i by doing this ["data":[[String:AnyObject]]]. You will probably have to change your api end point though.
