swift 3，wcf服务 [英] swift 3, wcf service

问题描述

我正在尝试在以Swift 3编码的IOS APP中使用现有的WCF服务. 问题似乎出在信封的格式.

I am trying to use an existing WCF service in an IOS APP coded in swift 3. The problem seem to be in the format of the envelope.

该服务在线且运行良好(已被android应用程序使用)

The service is on line and work well (is already used by an android app)

服务的网址:www.esmnovara.it \ FitnessManagerService.svc

URL of the service: www.esmnovara.it\FitnessManagerService.svc

这是从WCF测试客户端看到的请求:

This is the request, seen from a WCF test client:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/FitnessManagerIService/Login</Action>
  </s:Header>
  <s:Body>
    <Login xmlns="http://tempuri.org/">
      <NomeUtente></NomeUtente>
      <Password></Password>
    </Login>
  </s:Body>
</s:Envelope>

它必须返回以下内容:

"
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header />
  <s:Body>
    <LoginResponse xmlns="http://tempuri.org/">
      <LoginResult>0|ERRORE GENERICO, RIVOLGERSI ALLA RECEPTION</LoginResult>
      <NomeUtente a:nil="true" xmlns:a="http://www.w3.org/2001/XMLSchema-instance" />
      <Password a:nil="true" xmlns:a="http://www.w3.org/2001/XMLSchema-instance" />
    </LoginResponse>
  </s:Body>
</s:Envelope>
"

这是我的IOS swift 3应用程序的代码:

This is the code of my IOS swift 3 app:

 var soapMessage : String = ""
    soapMessage += "<s:Envelope xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'>"
    soapMessage += "<s:Header>"
    soapMessage += "<Action s:mustUnderstand='1' xmlns='http://schemas.microsoft.com/ws/2005/05/addressing/none'>http://tempuri.org/FitnessManagerIService/Login</Action>"
    soapMessage += "</s:Header>"
    soapMessage += "<s:Body>"
    soapMessage += "<Login xmlns='http://tempuri.org/FitnessManagerIService/Login'>"
    soapMessage += "<NomeUtente></NomeUtente>"
    soapMessage += "<Password></Password>"
    soapMessage += "</Login>"
    soapMessage += "</s:Body>"
    soapMessage += "</s:Envelope>'"


    let urlString = "http://www.esmnovara.it/FitnessManagerService.svc"


    let url = URL(string: urlString)

    let theRequest = NSMutableURLRequest(url: url!)

    let msgLength = soapMessage.characters.count

    theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
    theRequest.addValue(String(msgLength), forHTTPHeaderField: "Content-Length")
    theRequest.httpMethod = "POST"
    theRequest.httpBody = soapMessage.data(using: String.Encoding.utf8, allowLossyConversion: false) // or false

    let connection = NSURLConnection(request: theRequest as URLRequest, delegate: self, startImmediately: true)
    connection!.start()

    if (connection != nil) {
        var mutableData : Void = NSMutableData.initialize()


        //debugPrint(mutableData)
    }

这就是我得到的:

"IIS 8.5 Detailed Error - 400.0 - Bad Request"
"HTTP Error 400.0 - Bad Request"
"Bad Request"
"Detailed Error Information:"
"Module"
"IsapiModule"
"Notification"

"Error Code"

"Requested URL"

"D:\\LogFiles\\FailedReqLogFiles"
"More Information:"
" \n  The request could not be understood by the server due to malformed syntax. \n  "

有人可以帮助我吗?

推荐答案

我写了一个看起来很有效的操场脚本:

I wrote a little playground script which seems to work:

import UIKit
import PlaygroundSupport

// Ignore the next line, it's just to avoid a annoying message in Playgrounds
URLCache.shared = URLCache(memoryCapacity: 0, diskCapacity: 0, diskPath: nil)

// Service URL
let serviceUrl = URL(string: "http://www.esmnovara.it/FitnessManagerService.svc")
// Service request using the serviceURL
var serviceRequest = URLRequest(url: serviceUrl!)

// Set a couple of headers
serviceRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
serviceRequest.addValue("http://tempuri.org/FitnessManagerIService/Login", forHTTPHeaderField: "SOAPAction")

// Set the http verb
serviceRequest.httpMethod = "POST"

// Soap message
let soapMessageAsText = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><Login xmlns=\"http://tempuri.org/\"><NomeUtente/><Password/></Login></s:Body></s:Envelope>"
// Enconded as data
let soapMessageAsData = soapMessageAsText.data(using: String.Encoding.utf8)
// Set message as data in the http body of the request
serviceRequest.httpBody = soapMessageAsData

// Call the service using URLSession
URLSession.shared.dataTask(with: serviceRequest) { (data, response, error) in
   // Check for error
   guard error == nil else {
      print(error ?? "Unknown error")
      return
   }
   // Display data as string
   let dataAsString = String(data: data!, encoding: String.Encoding.utf8)
   print(dataAsString)

   }.resume()

// Ignore this line, it's neccesary so that playground waits
PlaygroundPage.current.needsIndefiniteExecution = true

希望它能起作用.
