致命异常：主要：okhttp3.RealCall.execute

Question

当我单击按钮时，我在我的 android 应用程序中使用 OkHttp 向 rapidapi API 发出网络请求。我已经在我的清单中添加了 INTERNET 权限和android:usesCleartextTraffic="true"。但我有错误

    AndroidRuntime: FATAL EXCEPTION: main
        Process: com.ex.fbinstadownloader, PID: 27537

            at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1386)
    Application terminated.

我的代码

 private fun StartDwonload() {
    val url = editText.text.toString()


        val client = OkHttpClient()

        val requests = Request.Builder()
            .url("xxxxxxxxxxigurl="+url)
            .get()
            .addHeader("x-rapidapi-host", "xxxxxx")
            .addHeader("x-rapidapi-key", "xxxxxxx")
            .build()

        val responses: Response = client.newCall(requests).execute()

        print(responses.body()?.string())


    }

我是 kotlin 的新手，请有什么想法

您通过此链接分享的代码https://play.kotlinlang.org/， 你已经使用过 OkHttp 和 DownloadManager。

请使用以下代码，

private fun StartDwonload() {
    val url = editText.text.toString()

        val client = OkHttpClient()

        val requests = Request.Builder()
            .url("https://instagram-facebook-media-downloader.p.rapidapi.com/api?igurl="+url)
            .get()
            .addHeader("x-rapidapi-host", "xxxxxx")
            .addHeader("x-rapidapi-key", "xxxxxxx")
            .build()

       // val responses: Response = client.newCall(requests).execute()

        client.newCall(requests).enqueue(object : Callback {
            override fun onFailure(call: Call, e: IOException) {}
            override fun onResponse(call: Call, response: Response) = println(response.body?.string())
        })
    }

在我删除此行val responses: Response = client.newCall(requests).execute()后工作正常@
