如何使用带有 xml 正文的 alamofire 发送请求

Question

我在我的项目中安装了 Alamofire，现在我已经完成了。

我安装了 postman 并将我的 url 和一个 xml 对象放入 body 中，我得到了我的结果。

这是一张我用 postman 做的照片

我现在如何使用 Alamofire 或 SWXMLHash 发送它，就像我用邮递员发送它一样

提前致谢！

我从另一个问题试过了：

 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)   


    }
}

但是它没有发送任何东西

这是日志：

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"; } })

永远不要忘记传递参数，如果你没有简单的添加这个，参数：Dictionary()

Answer 1

假设您在请求中缺少有效的 HTTP headers，更新后的请求可能如下所示：

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)   
    }
}

所以，基本上你应该加一行

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

更新:
尝试相同，但使用 responseData 或 responseString 而不是 responseJSON 因为您的回复可能不是 JSON

使用 Swift 3 和 Alamofire 4，您将创建自定义 ParameterEncoding。与任何其他 XML 编码的正文一样，SOAP 消息可以使用此参数编码，如下例所示。可以类似地创建其他 XML 正文编码（检查显示 urlRequest.httpBody = ... 的行）：

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
    }
}

然后像这样使用它：

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

使用 Swift 3 和 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)
    }
