Is there any EASY way to get the body's object content from Ktor client's MockEngine's requestHistory?

[Aleksei Tirman [JB]]

Do you want to get a request body from the history as an object that was passed to the setBody ?

[dave08]

One possibility... or just use the installed json deserializer...

@Aleksei Tirman [JB]?

I'm struggling with MockEngine, which would have been the best way to test, but compare that to: https://github.com/marcinziolo/kotlin-wiremock which seems to be much nicer, and has an easy way to assert things.

This is what I did on my project:

/**
 * Decode the body content from this request into a [String] in UTF-8.
 */
suspend fun OutgoingContent.decodeContent(): String =
    toByteArray().decodeToString()

/**
 * Decode the body content from a [String] in UTF-8 into a serializable type [T].
 */
@JvmName("decodeContentSerialization")
suspend inline fun <reified T> OutgoingContent.decodeContent(): T =
    Json.decodeFromString(decodeContent())

[dave08]

It gives me:
Type mismatch.
Required:
DeserializationStrategy<TypeVariable(T)>
Found:
String
No value passed for parameter 'string'

[dave08]

(the second one...)

[Aleksei Tirman [JB]]

How do you call that method?

[Kevin Del Castillo]

decodeFromString is an extension function for Json :

import kotlinx.serialization.decodeFromString

[dave08]

Yeah, I would have thought that Intellij was smart enough to auto-import that kind of thing by now...

[dave08]

@Aleksei Tirman [JB] I would use it in a matching framework like Strikt, to see if the expected request was received by the MockEngine
