无法使用 HTTP 客户端访问 REST API

如何解决无法使用 HTTP 客户端访问 REST API

我正在尝试使用 Scala 和 HTTP 客户端库访问 RestAPI(Databricks)，但无法获得正确响应。

我正在尝试使用 Bearer token 访问，并且端点是 https://somename.cloud.databricks.com/api/2.0/jobs/runs/list?active_only=true&limit=15。从 EC2 机器和 AWS 上的 Databricks 集群访问此端点。当我从本地机器（通过 IDE）执行时，相同的代码给出了正确的响应。

代码如下：

def listOutJobs(endpoint:String,givenToken:String):Unit={
 val url:URLConnection = new URL(endpoint).openConnection()
 val conn:HttpsURLConnection = url.asInstanceOf[HttpsURLConnection]
 conn.setRequestProperty("Authorization","Bearer "+givenToken)
 conn.setRequestProperty("Content-Type","application/json")
 conn.setDoOutput(true)
 conn.setRequestMethod("GET")
 println(conn.getResponseCode)
 val in : BufferedReader = new BufferedReader(new InputStreamReader(conn.getInputStream))
 var output : String = ""
 val response:StringBuffer = new StringBuffer()


 while ( output != null) {
   println(output)
   response.append(output)
   output = in.readLine()
 }
 conn.getHeaderField("Authorization")
 println(conn.getHeaderFields)
 in.close()
 println("Response:-" + response.toString)
}

即使我也尝试过下面的代码，但都给出了相同的响应。

def callPostMethod(endpoint:String,givenToken:String):Unit={
      val httpClient:CloseableHttpClient = HttpClients.createDefault()
      val httppost:HttpGet = new HttpGet(endpoint)
      httppost.addHeader("Authorization","Bearer "+givenToken)
      httppost.addHeader("Content-Type","application/json")
     httppost.addHeader("user-agent","Mozilla/5.0")
     val response:CloseableHttpResponse = httpClient.execute(httppost)
     val statusLine:StatusLine = response.getStatusLine
     println(scala.io.source.fromInputStream(response.getEntity.getContent).mkString)
     println(statusLine.getStatusCode)
     println(statusLine)
    httppost.getAllHeaders.foreach(x => x.getElements.foreach(z => z.getName))
   }

def AllowRedirect(endpoint:String,givenToken:String):Unit={
    val instance:HttpClient = HttpClientBuilder.create().setRedirectStrategy(new 
    LaxRedirectStrategy()).build()
    val httpGet = new HttpGet(endpoint)
    httpGet.addHeader("Authorization","Bearer "+givenToken)
    httpGet.addHeader("Content-Type","application/json")
    val response:HttpResponse = instance.execute(httpGet)
    println(response.getStatusLine.getStatusCode)
    println(response)
  }

下面是 HTML 格式的响应，我得到的响应代码是 200。

有人可以帮助我吗。
