我开始在当前的ios项目中使用cocoapods。我需要使用SOAP以简单的方式为我的ios项目获取内容。我用Google搜索了它，Alamofire pod对我来说很棒。因为我使用的是Swift编程语言。
我很容易看到这个吊舱。但我的Web服务返回XML结果。我想序列化来排列这个XML结果。但我不能。
当我用浏览器调用我的Web服务时，我得到了这种结果
Alamofire响应方法是这样的：
Alamofire.request(.GET, "http://my-web-service-domain.com", parameters: nil)
.response { (request, response, data, error) in
println(request)
println(response)
println(error)
}
当我运行此方法时，我在终端上看到此输出：
<NSMutableURLRequest: 0x170010a30> { URL: http://my-web-service-domain.com }
Optional(<NSHTTPURLResponse: 0x1704276c0> { URL: http://my-web-service-domain.com } { status code: 200, headers {
"Cache-Control" = "private, max-age=0";
"Content-Length" = 1020;
"Content-Type" = "text/xml; charset=utf-8";
Date = "Thu, 18 Jun 2015 10:57:07 GMT";
Server = "Microsoft-IIS/7.5";
"X-AspNet-Version" = "2.0.50727";
"X-Powered-By" = "ASP.NET";
} })
nil
我想得到一个数组的结果，在浏览器上看到我的故事板。任何人都可以帮助我如何使用Alamofire框架或Swift语言序列化这些数据？
如果我没有误解你的描述，我想你想获取XML数据并解析它，对吧？对此，您可以在响应回调中处理错误的变量。您应该println(data)检查XML文档。
要解析XML数据，可以考虑使用SWXMLHash。 Alamofire请求可能如下所示：
Alamofire.request(.GET, "http://my-web-service-domain.com", parameters: nil)
.response { (request, response, data, error) in
println(data) // if you want to check XML data in debug window.
var xml = SWXMLHash.parse(data!)
println(xml["UserDTO"]["FilmID"].element?.text) // output the FilmID element.
}
有关XML管理的更多信息，请查看SWXMLHash。
Alamofire 4.x - Swift 3.x：
（请注意，在这个例子中我使用URLEncoding.default而不是URLEncoding.xml，因为xml参数排除了传递参数和标题的可能性，因此default更加舒适。）
let url = "https://httpbin.org/get"
let parameters: Parameters = ["foo": "bar"]
let headers: HTTPHeaders = [
"Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==",
"Accept": "application/json"
]
Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers)
.responseString { response in
print(" - API url: \(String(describing: response.request!))") // original url request
var statusCode = response.response?.statusCode
switch response.result {
case .success:
print("status code is: \(String(describing: statusCode))")
if let string = response.result.value {
print("XML: \(string)")
}
case .failure(let error):
statusCode = error._code // statusCode private
print("status code is: \(String(describing: statusCode))")
print(error)
}
}
Alamofire 2015年10月3日和Xcode 7根据3.0.0-beta.3 README和Alamofire 3.0 Migration Guide。
对我来说，正确的语法是：
Alamofire.request(.GET, url, parameters: params, encoding: ParameterEncoding.URL).responsePropertyList { response in
if let error = response.result.error {
print("Error: \(error)")
// parsing the data to an array
} else if let array = response.result.value as? [[String: String]] {
if array.isEmpty {
print("No data")
} else {
//Do whatever you want to do with the array here
}
}
}
如果你想要一个好的XML解析器，请看看SWXMLHash。
一个例子可能是：let xml = SWXMLHash.parse(string)
截至2015年9月使用Alamofire 3.0当前版本和Xcode 7。
下面的实现具有不使用诸如SWXMLHash之类的附加外部库的优点
Alamofire.request(.GET, urlString, encoding: .PropertyList(.XMLFormat_v1_0, 0)).responsePropertyList { request, response, result in
//Note that result have two properties: error and value as of Alamofire 3.0, check the migration guide for more info
if let error = result.error {
print("Error: \(error)")
// parsing the data to an array
} else if let array = result.value as? [[String: String]] {
if array.isEmpty {
print("No data")
} else {
//Do whatever you want to do with the array here
}
}
}
如果要将XML映射到swift对象，您还可以考虑使用XMLMapper。 （使用与ObjectMapper相同的技术）
通过实现XMLMappable协议创建您的模型：
class UserDTO: XMLMappable {
var nodeName: String!
var extensionData: String?
var canChangeDeviceConfig: BooleanAtttribute?
var canChangeDriverConfig: BooleanAtttribute?
var canChangeFleetConfig: BooleanAtttribute?
var canChangeGeofenceConfig: BooleanAtttribute?
var canSaveHistory: BooleanAtttribute?
var canViewReport: BooleanAtttribute?
var canWatchHistory: BooleanAtttribute?
var deliverDailyReportByEmail: BooleanAtttribute?
var deliverDailyReportBySms: BooleanAtttribute?
var email: String?
var firm: String?
var firmId: Int?
var firstName: String?
var id: Int?
var isActive: Bool?
var isAdmin: Bool?
var lastName: String?
var phone: String?
var recivesDailyReport: BooleanAtttribute?
var userName: String?
required init(map: XMLMap) {
}
func mapping(map: XMLMap) {
extensionData <- map["ExtensionData"]
canChangeDeviceConfig <- map["CanChangeDeviceConfig"]
canChangeDriverConfig <- map["CanChangeDriverConfig"]
canChangeFleetConfig <- map["CanChangeFleetConfig"]
canChangeGeofenceConfig <- map["CanChangeGeofenceConfig"]
canSaveHistory <- map["CanSaveHistory"]
canViewReport <- map["CanViewReport"]
canWatchHistory <- map["CanWatchHistory"]
deliverDailyReportByEmail <- map["DeliverDailyReportByEmail"]
deliverDailyReportBySms <- map["DeliverDailyReportBySms"]
email <- map["Email"]
firm <- map["Firm"]
firmId <- map["FirmId"]
firstName <- map["FirstName"]
id <- map["Id"]
isActive <- (map["IsActive"], BooleanTransformeType(trueValue: "true", falseValue: "false"))
isAdmin <- (map["IsAdmin"], BooleanTransformeType(trueValue: "true", falseValue: "false"))
lastName <- map["LastName"]
phone <- map["Phone"]
recivesDailyReport <- map["RecivesDailyReport"]
userName <- map["UserName"]
}
}
class BooleanAtttribute: XMLMappable {
var nodeName: String!
var booleanValue: Bool?
required init(map: XMLMap) {
}
func mapping(map: XMLMap) {
booleanValue <- (map.attributes["xsi:nil"], BooleanTransformeType(trueValue: "true", falseValue: "false"))
}
}
class Firm: XMLMappable {
var nodeName: String!
var extensionData: String?
var firmTypeId: Int?
var id: Int?
var name: String?
var parentFirmId: Int?
required init(map: XMLMap) {
}
func mapping(map: XMLMap) {
extensionData <- map["ExtensionData"]
firmTypeId <- map["FirmTypeId"]
id <- map["Id"]
name <- map["Name"]
parentFirmId <- map["ParentFirmId"]
}
}
class BooleanTransformeType<T: Equatable>: XMLTransformType {
typealias Object = Bool
typealias XML = T
private var trueValue: T
private var falseValue: T
init(trueValue: T, falseValue: T) {
self.trueValue = trueValue
self.falseValue = falseValue
}
func transformFromXML(_ value: Any?) -> Bool? {
if let value = value as? T {
return value == trueValue
}
return nil
}
func transformToXML(_ value: Bool?) -> T? {
if value == true {
return trueValue
}
return falseValue
}
}
并使用XMLMapper类将XML字符串映射到模型对象：
let userDTO = XMLMapper<UserDTO>().map(XMLString: xmlString)
您可以使用Requests subspec和responseXMLObject(completionHandler:)函数将响应直接映射到模型对象中：
Alamofire.request("http://my-web-service-domain.com", method: .get).responseXMLObject { (response: DataResponse<UserDTO>) in
let userDTO = response.result.value
print(userDTO?.id ?? "nil")
}
我希望这很有用。
我有一个非常独特的问题，即服务器返回一个将JSON作为字符串的XML。希望它会帮助某人。
基本上XML看起来像这样：
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">{"Response":{"Status":"success","Result_Count":"1","Error_Description":"","Result":{"Login_result":{"user_id":"1","user_type":"1","user_name":"h4cked","user_locked":"False","user_locked_message":""}}}}</string>
正如您所看到的，实际的JSON是{"Response":....
该解决方案仅基于Alamofire 4.4。
你需要做的是：
.responsePropertyList[String : Any]这里是：
Alamofire.request(NetworkAPIPaths.pathForLogin(),
method: .get,
parameters: [APIParameters.userName.rawValue : "",
APIParameters.password.rawValue : ""]).responsePropertyList
{ (response : DataResponse<Any>) in
if let error = response.result.error
{
// Error...
}
else if let jsonFullString = response.result.value as? String
{
if let jsonStringAsData = jsonFullString.data(using: .utf8)
{
do
{
let jsonGhost = try JSONSerialization.jsonObject(with: jsonStringAsData, options: [])
if let actualJSON = jsonGhost as? [String : Any]
{
// actualJSON is ready to be parsed :)
}
}
catch
{
print (error.localizedDescription)
}
}
}
tsaiid在Swift 3和Alamofire 4中的回答：
Alamofire.request("http://my-web-service-domain.com", parameters: nil) //Alamofire defaults to GET requests
.response { response in
if let data = response.data {
println(data) // if you want to check XML data in debug window.
var xml = SWXMLHash.parse(data)
println(xml["UserDTO"]["FilmID"].element?.text) // output the FilmID element.
}
}
