将 Swift 与 URLSession 一起使用可用于 GET 和 PUT，但在我使用 POST 时会出现错误 405 Method Not Allowed
Using Swift with URLSession works with GET and PUT, but it gives error 405 Method Not Allowed when I use POST
我使用 Swift 开发了一个 iOS 应用程序。
我使用以下方法通过 PUT 方法访问登录端点。
let loginData = LoginModel("myUser","myPassword")
var loginClassJson:Data?
do{
loginClassJson = try JSONEncoder().encode(loginData)
} catch {
fatalError("Unable To Convert in Json")
}
let completeUrl = URL(string: RESconstantes.URL_PRINCIPAL_TREINAGEDAVE + "/login" )!
var request = URLRequest(url: completeUrl)
let myConfig = URLSessionConfiguration.default
let base64LoginString = EndpointController.getBase64StringLoginWithUserAndPasswordV2()
myConfig.httpAdditionalHeaders = ["Authorization" : base64LoginString]
request.httpMethod = "PUT"
request.setValue("\(String(describing: loginClassJson!.count))", forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = loginClassJson
let sessionDelegate = SessionDelegate()
let urlSession = URLSession(configuration: myConfig, delegate: sessionDelegate, delegateQueue: OperationQueue.main)
let task = urlSession.dataTask(with: request as URLRequest, completionHandler: {
(data, response, error) in
if let error = error{
print("errorX: ")
print(error)
return
}
if let data = data{
let returnData = String(data: data, encoding: String.Encoding.ascii)
print("dataX: ")
print(returnData)
}
if let response = response{
print("responseX: ")
print(response)
}
})
task.resume()
print("END")
这是我的 URLSessionDelegate class
class SessionDelegate:NSObject, URLSessionDelegate
{
func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
// usado para fazer o bypass na autenticação self-signed do certificado do servidor
// We've got a URLAuthenticationChallenge - we simply trust the HTTPS server and we proceed
print("start didReceive challenge 1")
if true {
print("didReceive challenge 2")
completionHandler(.useCredential, URLCredential(trust: challenge.protectionSpace.serverTrust!))
}else{
completionHandler(.performDefaultHandling, nil)
}
}
它非常适合我，但现在我尝试创建代码以使用 POST 方法
访问另一个端点
let resDadoModel = ResDadoModel.getResenhaById(1)
let jsonRequestUploadResenha = ResDadoModel.createMockJsonObjectResenhaDados(resDadoModel)
let json: [String: Any] = jsonRequestUploadResenha
guard let jsonData:Data = try? JSONSerialization.data(withJSONObject: json) else {
print("guard jsonData error")
return
}
let completeUrl = URL(string: RESconstantes.URL_PRINCIPAL_TREINAGEDAVE + "/validaResenha" )!
var request = URLRequest(url: completeUrl)
let myConfig = URLSessionConfiguration.default
let base64LoginString = EndpointController.getBase64StringLoginWithUserAndPasswordV2()
myConfig.httpAdditionalHeaders = ["Authorization" : base64LoginString, "Content-Type":""]
request.httpMethod = "POST"
request.setValue("\(String(describing: jsonData.count))", forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
let sessionDelegate = SessionDelegate()
let urlSession = URLSession(configuration: myConfig, delegate: sessionDelegate, delegateQueue: OperationQueue.main)
let task = urlSession.dataTask(with: request as URLRequest, completionHandler: {
(data, response, error) in
if let error = error{
print("errorX: ")
print(error)
return
}
if let data = data{
let returnData = String(data: data, encoding: String.Encoding.ascii)
print("dataX: ")
print(returnData)
}
if let response = response{
print("responseX: ")
print(response)
}
})
task.resume()
print("END")
但是我用来访问名为“validaResenha”的端点的代码无法正常工作，我收到 405 方法不允许错误。
我得到以下响应数据
<NSHTTPURLResponse: 0x600002028560> { URL: https://my_url_endpoint/api/spservicos/v1/validaResenha } { Status Code: 405, Headers {

} }
有人知道为什么我收到不允许的 405 错误方法吗？如果我使用 POSTMAN，POST 方法对我有用。如果我将 PUT 或 GET 端点与 Swift 代码一起使用，它会起作用，但如果我尝试在 Swift.
中尝试将端点与 POST 方法一起使用，它就会失败
我看到了一些奇怪的东西，“Content-Type”在响应中定义为 text/plain，但我将其设置为“application/json”。我不明白为什么没有设置配置。
如果我通过 POSTMAN 调用它，它可以工作，但出于某种原因我不知道为什么当我使用 Swift.
时它不工作
--- 编辑 ---
根据@matt 的建议，我使用 Postman 生成 Swift 代码。
我将 Swift 代码复制并粘贴到我的项目中，这是代码：

但我现在收到 401 错误。出于某种原因，基本身份验证未被代码或服务器接受。
我检查了用户和密码，它们是正确的。
我找到了解决问题的方法。
我在常量文件中使用“http://MY_ENDPOINT/validaResenha”而不是“https://MY_ENDPOINT/validaResenha”。
将“s”添加到“http”字母（它变成“https”）后，一切开始为我工作。
奇怪的是，由于从 HTTP 重定向到 HTTPS，GET 和 PUT 方法工作正常，但在 POST 调用的情况下，我遇到了这个错误。
现已修复。
