How to send a request with alamofire with xml Body

问题

I installed Alamofire in my project and now here is what I have done.

I installed postman and I put my url and inside body a xml object and I got my result.

Here is a picture of what I exactly have done with postman

How can I now use Alamofire or SWXMLHash to send it as I send it with postman

Thanks in advance!

EDIT

I tried this from another question:

 Alamofire.request(.POST, "https://something.com" , parameters: Dictionary(), encoding: .Custom({
            (convertible, params) in
            let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest

            let data = (self.testString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
            mutableRequest.HTTPBody = data
            return (mutableRequest, nil)
        }))


    .responseJSON { response in


    print(response.response) 

    print(response.result)   


    }
}

But it didn't send anything

This is the log:

Optional( { URL: https://something.com } { status code: 200, headers { Connection = "keep-alive"; "Content-Length" = 349; "Content-Type" = "application/xml"; Date = "Wed, 02 Nov 2016 21:13:32 GMT"; Server = nginx; "Strict-Transport-Security" = "max-age=31536000; includeSubDomains"; } })

FAILURE

EDIT

NEVER FORGET TO PASS parameters if you don't have simple add this , parameters: Dictionary()

Assuming you that you're missing valid HTTP headers in your request, the updated request could look like:

Alamofire.request(.POST, "https://something.com", parameters: Dictionary() , encoding: .Custom({
            (convertible, params) in
            let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest

            let data = (self.testString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
            mutableRequest.HTTPBody = data
            mutableRequest.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
            return (mutableRequest, nil)
        }))
    .responseJSON { response in
    print(response.response) 
    print(response.result)   
    }
}

So, basically you should add one line

mutableRequest.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")

Update:
Try same, but use responseData or responseString instead of responseJSON because it is possible that your response is not JSON

Using Swift 3 and Alamofire 4

    let stringParams : String = "<msg id=\"123123\" reqTime=\"123123\">" +
        "<params class=\"API\">" + 
        "<param name=\"param1\">123213</param>" + 
        "<param name=\"param2\">1232131</param>" +
        "</params>" +
    "</msg>"

    let url = URL(string:"<#URL#>")
    var xmlRequest = URLRequest(url: url!)
    xmlRequest.httpBody = stringParams.data(using: String.Encoding.utf8, allowLossyConversion: true)
    xmlRequest.httpMethod = "POST"
    xmlRequest.addValue("application/xml", forHTTPHeaderField: "Content-Type")


    Alamofire.request(xmlRequest)
            .responseData { (response) in
                let stringResponse: String = String(data: response.data!, encoding: String.Encoding.utf8) as String!
                debugPrint(stringResponse)
    }

With Swift 3 and Alamofire 4 you would create a custom ParameterEncoding. As with any other XML encoded body, SOAP messages can use this parameter encoding as in the following example. Other XML body encodings can be created similarly (check the line where it says urlRequest.httpBody = ...):

struct SOAPEncoding: ParameterEncoding {
    let service: String
    let action: String

    func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var urlRequest = try urlRequest.asURLRequest()

        guard let parameters = parameters else { return urlRequest }

        if urlRequest.value(forHTTPHeaderField: "Content-Type") == nil {
            urlRequest.setValue("text/xml", forHTTPHeaderField: "Content-Type")
        }

        if urlRequest.value(forHTTPHeaderField: "SOAPACTION") == nil {
            urlRequest.setValue("\(service)#\(action)", forHTTPHeaderField: "SOAPACTION")
        }

        let soapArguments = parameters.map({key, value in "<\(key)>\(value)</\(key)>"}).joined(separator: "")

        let soapMessage =
            "<s:Envelope xmlns:s='http://schemas.xmlsoap.org/soap/envelope/' s:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'>" +
            "<s:Body>" +
            "<u:\(action) xmlns:u='\(service)'>" +
            soapArguments +
            "</u:\(action)>" +
            "</s:Body>" +
            "</s:Envelope>"

        urlRequest.httpBody = soapMessage.data(using: String.Encoding.utf8)

        return urlRequest
    }
}

And then use it like that:

Alamofire.request(url, method: .post, parameters: ["parameter" : "value"], encoding: SOAPEncoding(service: "service", action: "action"))
