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。
这是我在做什么：
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)
它总是返回超时错误：

如果我只是做
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，还有其他简单的发送https请求的方法吗？即使涉及到
spray框架，也没关系（不过，我没有在spray中找到如何执行此操作的任何示例）。更新：
从这里取一个例子Doing HTTP request in Scala
最佳答案
您需要使用.option(HttpOptions.connTimeout(10000)).option(HttpOptions.readTimeout(50000))指定连接超时以及当前的读取超时。将10000更改为适合您的值。默认的连接超时是非常激进的100。
您确实已经指定了读取超时，但是异常表明它是在建立连接而不是在读取响应时超时。

关于json - 我使用Scalaj请求时出现SocketTimeoutException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17007127/
