Question

我试图获取一个带有api标头的json帖子。但是当我在测试设备上创建该程序时崩溃了。

我曾经尝试浏览过论坛，但没有发现来自http3的哪些错误导致了这种情况。

私有val客户端= OkHttpClient（）

@Throws(Exception::class)
fun fetchJson() {
    val formBody = FormBody.Builder()
        //json im trying to post

        .addEncoded("body", "{\n" +

        .addHeader("AccessToken","9EB227BC-A820-81CA-7607737B4809AA6E")
        .addHeader("CompanyName","PAWS")
        .addHeader("InterfaceName","ForwardPOS")
        .addHeader("InterfaceVersion","2.1")
        .post(formBody)
        .build()

    val response = client.newCall(request).execute()
    if (!response.isSuccessful) throw IOException("Unexpected code $response")

    System.out.println(response.body()?.string())
}

我希望程序能够运行，因此可以与api通讯，但不会。

Answer 1

您不能在主线程上发出网络请求。将其包装在异步任务中。

我有一个http发布请求，但现在尝试运行应用程序时，主要活动在oncreate时崩溃
