My iOS app obtains streamed events from an endpoint. I use the following code successfully to initiate streaming and worked beautifully before iOS 13. Now the following code will generate an error:
func startStreaming() {
precondition( !self.isStreaming )
//
// create a request and task to start streaming
//
if let request = SensorInventory.setupHTTPRequestForURL(SensorProject.projectBaseUrlString + "/devices:stream") {
let task = self.session.uploadTask(withStreamedRequest: request)
self.streamingTask = task
task.resume()
}
}
The method setupHTTPRequestForURL simply creates a request object with a base 64 encoded string of key and password and sets the value for the httpHeaderField:
request.httpMethod = "GET"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")
No error is thrown in iOS 12 - streamed data is returned however in iOS 13:
2019-09-22 18:00:27.728325-0700 DTSensors[9880:1176642] GET method must not have a body

When I examine the request structure I see (sensitive data is removed at ***):
https://api.YYYY.com/v2/projects/XXXXXXXXX/devices:stream
▿ url : Optional<URL>
▿ some : https://api.YYYY.com/v2/projects/XXXXXXXXX/devices:stream
- _url : https://api.YYYY.com/v2/projects/XXXXXXXXX/devices:stream
- cachePolicy : 0
- timeoutInterval : 60.0
- mainDocumentURL : nil
- networkServiceType : __C.NSURLRequestNetworkServiceType
- allowsCellularAccess : true
▿ httpMethod : Optional<String>
- some : "GET"
▿ allHTTPHeaderFields : Optional<Dictionary<String, String>>
▿ some : 1 element
▿ 0 : 2 elements
- key : "Authorization"
- value : "Basic Ymhxb2hlajI0dGUwMDBiMjR2ajA6NjQ0YWQ2MTgxN2E0NDA3MWI4OTEyM2EwNzI2ZGE2MTY="
- httpBody : nil
- httpBodyStream : nil
- httpShouldHandleCookies : true
- httpShouldUsePipelining : false
- Note that the httpBody is nil in contrast to what the output above describes
Anyone have a suggestion about how to address this problem? NB The same basic authorization works just fine if I am asking the endpoint for data, it just does not work if I attempt to initiate streaming.
Thanks!
