因此,我正在尝试为Http请求集成Firebase性能,并在显示here时手动添加它们(步骤9)。
我正在使用Retrofit 2和RxJava 2,所以我想做一个自定义运算符,检查下面的代码:
改造2个客户
@GET("branch-{environment}/v2/branches")
fun getBranch(@Path("environment") environment: String, @Query("location") location: String, @Query("fulfilment_type") fulfilmentType: String): Single<Response<GetBranchResponse>>
RxJava调用Retrofit客户端
private val client: BranchClient = clientFactory.create(urlProvider.apiUrl)
override fun getBranch(postCode: String, fulfilmentType: FulfilmentType): Single<GetBranchResponse> {
return client
.getBranch(environment, postCode.toUpperCase(), fulfilmentType.toString())
.lift(RxHttpPerformanceSingleOperator(URL?, METHOD?))
.map { it.body() }
.subscribeIO() //custom Kotlin extension
.observeMain() //custom Kotlin extension
...
}
RxJava 2定制操作员通过电梯:
class RxHttpPerformanceSingleOperator<T>(private val url: String, private val method: String) : SingleOperator<Response<T>, Response<T>> {
private lateinit var metric: HttpMetric
@Throws(Exception::class)
override fun apply(observer: SingleObserver<in Response<T>>): SingleObserver<in Response<T>> {
return object : SingleObserver<Response<T>> {
override fun onSubscribe(d: Disposable) {
metric = FirebasePerformance.getInstance().newHttpMetric(url,
method.toUpperCase())
metric.start()
observer.onSubscribe(d)
}
override fun onSuccess(t: Response<T>) {
observer.onSuccess(t)
//More info: https://firebase.google.com/docs/perf-mon/get-started-android
metric.setRequestPayloadSize(t.raw().body().contentLength())
metric.setHttpResponseCode(t.code())
metric.stop()
}
override fun onError(e: Throwable) {
observer.onError(e)
metric.stop()
}
}
}
所以目前我不确定如何以正确的方式获取请求的URL和方法(标记为URL?和METHOD?)以发送给运营商,
我在onSubscribe上需要它们来启动指标 ..在那里我没有响应...
目前UGLYYYYYYY我的方式是:
添加到Retrofit客户端:
@GET("branch-{environment}/v2/branches")
fun getBranchURL(@Path("environment") environment: String, @Query("location") location: String, @Query("fulfilment_type") fulfilmentType: String): Call<JsonObject>
添加参数:
val request = client.getBranchURL(environment, postCode.toUpperCase(), fulfilmentType.toString()).request()
url = request.url().toString()
method = request.method()
这使我在每个请求的客户端上都有2个条目......这没有任何意义。
一路上有一些有用的线索: - How to get the request url in retrofit 2.0 with rxjava?

使用Interceptor
向您的HttpClient.Builder
添加改造FirebaseInstance
并在那里生成HttpMetrics
:
class FirebasePerformanceInterceptor(val performanceInstance: FirebasePerformance) : Interceptor {
override fun intercept(chain: Interceptor.Chain): Response {
val request = chain.request()
//Get request values
val url = request.url().url()
val requestPayloadSize = request.body()?.contentLength() ?: 0L
val httpMethod = request.method()
//Initialize http trace
val trace = performanceInstance.newHttpMetric(url, httpMethod)
trace.setRequestPayloadSize(requestPayloadSize)
trace.start()
//Proceed
val response = chain.proceed(chain.request())
//Get response values
val responseCode = response.code()
val responsePayloadSize = response.body()?.contentLength() ?: 0L
//Add response values to trace and close it
trace.setHttpResponseCode(responseCode)
trace.setResponsePayloadSize(responsePayloadSize)
trace.stop()
return response
}
}
您可以直接复制并粘贴此代码,它将起作用。 享受!

我要建议的不一定是你的方法,它只是一种不同的方式来思考你想要完成的事情。
