Question

我正在尝试通过此代码使用theDuckDuck go api

val mainVal = searchQuery.replace(" ", "+")
    val url = URL("https://api.duckduckgo.com/?q=$mainVal&format=json")
    println(url.host)
    url.openConnection()
    val json = url.readText()

我收到此错误

java.io.IOException: Server returned HTTP response code: 500 for URL: https://api.duckduckgo.com/?q=duck+duck+go&format=json

当我在浏览器中运行给定链接时，它将返回预期结果。我尝试使用HttpSConnection方法，但没有用。

请注意，我在https上已经多次使用这种方法，这不是问题。

确保在清单中添加了 INTERNET 权限

＆

使用 Uri.encode 方法对URL进行编码，而不是添加“ +”：

//        val mainVal = searchQuery.replace(" ", "+")

            val mainVal = Uri.encode(searchQuery)

            val url = URL("https://api.duckduckgo.com/?q=$mainVal&format=json")
            println(url.host)
            url.openConnection()
            val json = url.readText()
            println("Result = " + json)

在我的代码中出现错误500，但在浏览器中却没有
