Groovy / Grails-通過使用HTTPBuilder獲得HttpResponseException

Question

我嘗試從另一個Grails應用程序（MyApplication2）獲取Grails應用程序（MyApplication2）的數據。 兩者都在本地運行。 我使用以下代碼引發異常。

Groovy

try {
    def http = new HTTPBuilder('http://localhost:8080/MyApplication2')

    http.get( path : '/ControllerName/Action', contentType : ContentType.TEXT) { resp, reader ->

            println "response status: ${resp.statusLine}"
            resp.headers.each { h ->
                println " ${h.name} : ${h.value}"
            }

        }
} catch (groovyx.net.http.HttpResponseException ex) {
    ex.printStackTrace()
    println ex.toString()

} catch (java.net.ConnectException ex) {
    ex.printStackTrace()
    println ex.toString()       
}       

拋出異常

 Error 2015-10-28 10:13:43,448 [http-bio-8090-exec-1] ERROR errors.GrailsExceptionResolver  - HttpResponseException occurred when processing request: [GET] /MyApplication1/ControllerName/Action Not Found.

我終於找到了問題：我更改了URI格式。 我在URI的末尾添加了/ ，並在path的開頭刪除了/ 。

try {

        def http = new HTTPBuilder('http://localhost:8080/MyApplication2/')

        http.get( path : 'ControllerName/Action', contentType : ContentType.TEXT) { resp, reader ->

        println "response status: ${resp.statusLine}"
        resp.headers.each { h ->
            println " ${h.name} : ${h.value}"
        }

    }
} catch (groovyx.net.http.HttpResponseException ex) {
    ex.printStackTrace()
    println ex.toString()

} catch (java.net.ConnectException ex) {
    ex.printStackTrace()
    println ex.toString()       
}
