IOS Swift使用SOAP调用Web服务

我已经浏览了如何在互联网上通过SOAP窗体调用Web服务的答案，并find了一些答案。 我试图实现我在这些答案中find的代码，但不断得到一个HTTP 400状态代码。 我想弄清楚我做错了什么。

我已经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button时调用代码。 我想要调用的Web服务可以在http://www.cgsapi.com/CGSWebService.asmxfind。

（要查看WSDL文件，请在URL的末尾附加？wsdl。）

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() } } 

任何想法，当我打电话给我时，为什么我得到http 400状态？

Answer 1

所以我很傻。 这主要是因为我错过了将消息正文设置为Soap请求。 我更新的更正后的代码如下：

Answer 2

您可以使用以下代码进行Web服务调用。

  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") } } }

 - (BOOL)callWebService { NSString *soapMessage = @"<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>"; // SOAP request settings NSURL *url = [NSURL URLWithString:@"http://www.cgsapi.com/CGSWebService.asmx"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; NSURLSession *session = [NSURLSession sharedSession]; NSError *error; request.HTTPMethod = @"POST"; request.HTTPBody = [soapMessage dataUsingEncoding:NSUTF8StringEncoding]; [request addValue:@"www.cgsapi.com" forHTTPHeaderField:@"Host"]; [request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [request addValue:[NSString stringWithFormat:@"%i", soapMessage.length] forHTTPHeaderField:@"Content-Length"]; [request addValue:@"http://www.cgsapi.com/GetSystemStatus" forHTTPHeaderField:@"SOAPAction"]; NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"response: %@", response); NSString *output = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"output: %@", output); if (error !=nil) { NSLog(@"error: %i %@", error.code, error.description); } }]; [task resume]; return true; }

请参阅此链接https://github.com/blastar/Swift-SOAP-with-Alamofire 。 它给你一个更有条理的方法来处理与Almofire的肥皂。

1.使用cocoa豆荚可以导入下列豆荚

https://cocoapods.org/了解如何设置cocoa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 

这只是通过更有条理的almofire实施肥皂的一种方法。 你必须做一些小任务来根据你的实现进行定制

 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") } } } 

希望能帮助到你。
