Swift----使用Alamofire调用WebService

用于拼接地址的常量
直接上代码，这块代码是封装在NetAddressFile.swift类中

import Foundation

//测试地址
let kURLHeader = "http://192.168.2.17:9090/"

//请求的命名空间
let kNameSpace = "http://tempuri.org/"

//服务地址
enum Service:String {
        case UserService = "UserService.asmx"
        case ProductService = "ProductService.asmx"
        case StockService = "StockService.asmx"
}

//服务器接口地址
enum ServiceAction{
    
    enum UserServiceAction:String{
        case RegistAction = "Regist"
        case LogonAction = "Logon"
        case LogonTAction = "LogonT"
        case GetParameter = "GetParameter"
    }
    enum ProductServiceAction:String{
        case GetProductAction = "GetProduct"
        case AddProductAction = "AddProduct"
    }
    enum StockServiceAction :String{
        case AddStockAction = "AddStock"
        case UpdateCountAction = "UpdateCount"
        case GetStockAction = "GetStock"
    }
}

以下代码是NetWorkManager类，我们所用来请求数据的类
该类里面共有四个方法：

public func postRequest(_ service:String,action:String,paramValues:String,success:@escaping SuccessBlock){}

private func getURLRequest(_ action:String,URL:Foundation.URL,soapMsg:String)->URLRequest{}

private func getURL(_ service:String,action:String)->URL{}

 private   func toSoapMessage(_ action: String, pams: String) -> String {}

以上四个方法中我们使用第一个方法public func postRequest(_ service:String,action:String,paramValues:String,success:@escaping SuccessBlock){}请求数据,其他三个是为第一个服务的，以下是详细代码。

import UIKit
import Alamofire

//请求成功的回调
typealias SuccessBlock = (NSData)->Void
//请求失败的回调
typealias FaileBlock = (NSError)->Void

class NetWorkManager: NSObject{
    
    var         webData:                    NSMutableData!
    var         currentService:             String = String()
    var         currentAction:              String = String()
    var         successBlock:               SuccessBlock?
    var         fauleBlock:                 FaileBlock?
    
// 请求数据的时候使用这个类就可以
 public   func postRequest(service:String,action:String,paramValues:String,success:SuccessBlock){
        
        self.successBlock = success
        
        self.currentService = service
        
        self.currentAction = action
        
        let URL = getURL(service, action: action)
        print(URL)
        
        let soapMsg:String = toSoapMessage(action, pams: paramValues)
        
        let urlRequest: URLRequest = getURLRequest(action, URL: URL, soapMsg: soapMsg)
        
        
        Alamofire.request(urlRequest).responseData { response in

           if response.result.isSuccess{
                if let successful = self.successBlock{
                    successful(response.data!)
                }
            }else{
                 print("请求数据失败----》\(response.result.error?.description)")
            }
        }
        
    }

private func getURLRequest(_ action:String,URL:Foundation.URL,soapMsg:String)->URLRequest{
        
        var request:URLRequest = URLRequest(url: URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 1)
        request.setValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
        let soapAction = kNameSpace+action
        print("\(soapAction)")
        request.setValue(soapAction, forHTTPHeaderField: "SOAPAction")
        request.setValue("\(soapMsg.characters.count)", forHTTPHeaderField: "Content-Length")
        request.httpMethod = "POST"
        request.httpBody = soapMsg.data(using: String.Encoding.utf8)
        
        return request
    }
    
    /*
     Param:
     
        service:服务地址 eg.  ProductService.asmx
     
        action: 服务端口 eg.  GetProduct
     
     Return: "http://192.168.2.17:9090/ProductService.asmx?op=GetProduct"
     
     */
    
  private  func getURL(service:String,action:String)->NSURL{
        let urlStr = kURLHeader+service+"?op="+action
        return NSURL(string: urlStr)!
    }
    

    /*
     Description: 拼接请求的字符串
     
     Param:
     
        action:服务端口 eg.  GetProduct
     
        pams:需要上传的参数
     
     Return: 字符串
     */
    
private    func toSoapMessage(action: String, pams: String) -> String {
        var message: String = String()
        message += "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
        message += "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
        message += "<soap:Body>"
        message += "<\(action) xmlns=\"\(kNameSpace)\">"
        message += "\(pams)"
        message += "</\(action)>"
        message += "</soap:Body>"
        message += "</soap:Envelope>"
        return message
    }

}

上面的类写好之后，我们就可以使用了。

我们写了那么多就是为了，拼接出SOAP请求（参考图片中的SOAP请求）

使用方法如下：

// 直接调用这个方法就可以发起请求
比如：在我的后台方法中要求传入一个名为CountingEntryTable的数组
 func postData(){
        var message = "<data>"
        for item in self.dataArray {
          //FileDateModel是我自己定义的一个Model,可以修改为你们只的数据
            let fileModel:FileDataModel = item  as! FileDataModel
            message += "<CountingEntryTable>"
            message += "<skuCode>\(fileModel.skuCode!)</skuCode>"
            message += "<skuName>\(fileModel.skuName!)</skuName>"
            message += "<onHandQty>\(fileModel.onhandQty!)</onHandQty>"
            message += "<countQty>\(fileModel.countQty!)</countQty>"
            message += "<varianceQty>\(fileModel.varianceQty!)</varianceQty>"
            message += "</CountingEntryTable>"
        }
        message += "</data>"
/*
现在的message消息为：
<data>
        <CountingEntryTable>
            <skuCode>9787512408371</skuCode>
            <skuName>C语言</skuName>
            <onHandQty>20</onHandQty>

            <varianceQty>-2</varianceQty>
        </CountingEntryTable>
    </data>
*/
/*
最终的message为：

//最终的message当我们调用下面此方法后会自动生成，因为我们再`NetWorkManager`类中会进一步处理，该方法为toSoapMessage 
//先创建一个networkManager对象
    var      networkManager:         NetWorkManager = NetWorkManager()
      //该方法就是我们最终使用的方法，返回data数据，数据类型就是上图中的SOAP响应  
       networkManager.postRequest(Service.CountingEntry.rawValue, action: ServiceAction.CountEntryServiceAction.AddCount.rawValue, paramValues: message, success:{
