我正在尝试使用此库https://github.com/scalaj/scalaj-http发出一个简单的 https 请求。该请求包含一些 json 数据。

这是我正在做的事情：

  val jsonHeaders = """{"jsonrpc": "2.0", "method": "someMethod", "params": {"dataIds":["12348" , "456"]}, "data2": "777"}"""

  val result = Http.postData("https://someurl.com/json-rpc", jsonHeaders)
    .header("content-type", "application/json")
    .header("X-Application", "myCode")
    .header("X-Authentication", "myCode2")
    .option(HttpOptions.readTimeout(10000))
    .asString
    //.responseCode -- the same error

  println(result)

它总是给我一个超时错误：

如果我只是

val jsonHeaders = """{"version123": "12.0", "method": "someMethod", "params": {"dataIds": ["12348" , "456"]}, "data2": "777"}"""
val result = Http.postData("https://someurl.com/some-url2", jsonHeaders)
        .header("content-type", "application/json")
        .header("X-Application", "myCode")
        .header("X-Application1234", "myCode2")
        .option(HttpOptions.readTimeout(10000))
println(result)

它返回

Request(POST,<function2>,<function1>,List(),List((X-Authentication,myCode2), (X-Application1234,myCode), (content-type,application/json)),List(<function1>, <function1>, <function1>),DIRECT)

我做错了什么，还有其他简单的方法来发送 https 请求吗？即使涉及spray框架，也可以（不过，我没有找到任何关于如何做到这一点的示例spray）。

您需要在当前读取超时旁边指定连接超时：.option(HttpOptions.connTimeout(10000)).option(HttpOptions.readTimeout(50000))。将 更改10000为适合您的值。默认连接超时非常激进100。

您确实已经指定了读取超时，但异常表明它在建立连接时超时，而不是在读取响应时超时。

请参阅文档：https ://github.com/scalaj/scalaj-http#custom-connect-and-read-timeouts
