Question

我已经查看了如何通过互联网上的SOAP表格swift调用Web服务的答案，并找到了一些答案。我试图实现我在这些答案中找到的代码，但不断获得http 400状态代码。我想弄清楚我做错了什么。

我已将问题简化为视图控制器中的几行代码，如下所示，当按下UI上的按钮时，将调用代码。我试图拨打的网络服务可以在http://www.cgsapi.com/CGSWebService.asmx找到。

（要查看WSDL文件，请将？wsdl附加到URL的末尾。）

import UIKit

class ViewController: UIViewController {
var is_SoapMessage: String = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:cgs=\"http://www.cgsapi.com/\"><soapenv:Header/><soapenv:Body><cgs:GetSystemStatus/></soapenv:Body></soapenv:Envelope>"

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func btnClicked(sender: AnyObject)
{
    var is_URL: String = "http://www.cgsapi.com/CGSWebService.asmx"

    var lobj_Request = NSMutableURLRequest(URL: NSURL(string: is_URL)!)
    var session = NSURLSession.sharedSession()
    var err: NSError?

    lobj_Request.HTTPMethod = "POST"
    lobj_Request.addValue("www.cgsapi.com", forHTTPHeaderField: "Host")
    lobj_Request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
    //lobj_Request.addValue(String(count(is_SoapMessage)), forHTTPHeaderField: "Content-Length")
    lobj_Request.addValue("223", forHTTPHeaderField: "Content-Length")
    lobj_Request.addValue("http://www.cgsapi.com/GetSystemStatus", forHTTPHeaderField: "SOAPAction")

    var task = session.dataTaskWithRequest(lobj_Request, completionHandler: {data, response, error -> Void in
        println("Response: \(response)")
        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)
        println("Body: \(strData)")

        if error != nil
        {
            println("Error: " + error.description)
        }

    })
    task.resume()
}

}

当我打电话给我时，知道为什么我会获得http 400状态吗？

Answer 1

所以我很傻。主要的是我错过了将消息体设置为SOAP请求。我更新的更正后的代码如下：

    lobj_Request.HTTPMethod = "POST"

    //lobj_Request.addValue("223", forHTTPHeaderField: "Content-Length")
    lobj_Request.addValue("http://www.cgsapi.com/GetSystemStatus", forHTTPHeaderField: "SOAPAction")

        println("Response: \(response)")
        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)

        }

    })
    task.resume()

Swift 5.2，XCode 12

我或多或少地遵循了乔治对自己的反应所采取的方法。我认为保留一些具有最新swift和Xcode的代码示例可能对某些人有帮助：

private func exampleSoapRequest() {
    let url = URL(string: ProvidedData.urlString)!
    let request = NSMutableURLRequest(url: url)
    request.httpMethod = "POST"
    request.httpBody = ProvidedData.envelope.data(using: .utf8)
    request.addValue(String(ProvidedData.envelope.count), forHTTPHeaderField: "Content-Length")
    request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.addValue("<PUT HERE YOUR SOAP ACTION IF NEEDED>", forHTTPHeaderField: "SOAPAction")

    let task = URLSession.shared
        .dataTask(with: request as URLRequest,
                  completionHandler: { data, response, error in
                    guard error == nil else {
                        // Handle the error
                        print(error)
                    }

                    guard let data = data else {
                        return
                    }
                    // Continue checking response or data...
        })
    task.resume()
}

在ProvidedData中，我只是假设您会以某种方式传递您的网址和信封。

除此之外，如果您希望有一个更结构化和“基于参数”的信封，并且不介意使用外部库，那么@Pulkit Kumar Singh提出的AEXML解决方案也很有趣

您可以使用以下代码拨打网络服务电话。

 let url = NSURL(string: "https://www.google.com/")

        var request:NSMutableURLRequest = NSMutableURLRequest(URL:url!)
        var bodyData = "data=something"
        request.HTTPMethod = "POST"
        request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
        NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
            {
                (response, data, error) in
                print(response)
                if let HTTPResponse = response as? NSHTTPURLResponse {
                    let statusCode = HTTPResponse.statusCode

                    if statusCode == 200 {
                        // Yes, Do something. 
                    }else{
                         print("Error")
                         }
                }

        }

Answer 5

请参阅此链接https://github.com/blastar/Swift-SOAP-with-Alamofire。它为您提供了一种更有条理的方式来处理肥皂与Almofire。

1.使用可可豆荚，您可以导入以下豆荚

https://cocoapods.org/知道如何设置可可豆荚

use_frameworks!

target 'Swift-SOAP-with-Alamofire' do
pod 'Alamofire'
pod 'SWXMLHash'
pod 'AEXML'
pod 'StringExtensionHTML'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['CONFIGURATION_BUILD_DIR'] = '$PODS_CONFIGURATION_BUILD_DIR'
    end
  end
end

2。这只是通过更有条理的almofire实现肥皂的一种方式。你必须做一个小任务来根据你的实现进行自定义

func getCountries(completion: (result: [Country]) -> Void) -> Void {

        var result = [Country]()
        let soapRequest = AEXMLDocument()
        let envelopeAttributes = ["xmlns:SOAP-ENV" : "http://schemas.xmlsoap.org/soap/envelope/", "xmlns:ns1" : "http://www.webserviceX.NET"]
        let envelope = soapRequest.addChild(name: "SOAP-ENV:Envelope", attributes: envelopeAttributes)
        let body = envelope.addChild(name: "SOAP-ENV:Body")
        body.addChild(name: "ns1:GetCountries")

        let soapLenth = String(soapRequest.xmlString.characters.count)
        let theURL = NSURL(string: "http://www.webservicex.net/country.asmx")

        let mutableR = NSMutableURLRequest(URL: theURL!)
        mutableR.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
        mutableR.addValue("text/html; charset=utf-8", forHTTPHeaderField: "Content-Type")
        mutableR.addValue(soapLenth, forHTTPHeaderField: "Content-Length")
        mutableR.HTTPMethod = "POST"
        mutableR.HTTPBody = soapRequest.xmlString.dataUsingEncoding(NSUTF8StringEncoding)

        Alamofire.request(mutableR)
            .responseString { response in
                if let xmlString = response.result.value {
                    let xml = SWXMLHash.parse(xmlString)
                    let body =  xml["soap:Envelope"]["soap:Body"]
                    if let countriesElement = body["GetCountriesResponse"]["GetCountriesResult"].element {
                        let getCountriesResult = countriesElement.text!
                        let xmlInner = SWXMLHash.parse(getCountriesResult.stringByDecodingHTMLEntities)
                        for element in xmlInner["NewDataSet"]["Table"].all {
                            if let nameElement = element["Name"].element {
                                var countryStruct = Country()
                                countryStruct.name = nameElement.text!
                                result.append(countryStruct)
                            }
                        }
                    }
                    completion(result: result)
                }else{
                    print("error fetching XML")
                }
        }
    }
