My Citrus測試向某個REST API發送（旅行）請求。響應處理如下：有效負載中的意外字符
http()
.client("http://localhost:18082/cases")
.send()
.post()
.accept("application/json; charset=UTF-8")
.contentType("application/json")
//.payload(new ClassPathResource("templates/travelrequest.json"));
.payload(
"{ "+
"\"definition\": \"travelrequest.xml\", "+
"\"name\": \"travelrequest\" "+
"} "
);
雖然接收到響應代碼500，但這是我所期望的。在Wireshark的我抓住以下包：
Host: localhost:18082
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.3 (Java/1.8.0_121)
Accept-Encoding: gzip,deflate
{ "definition": "travelrequest.xml", "name": "travelrequest" } HTTP/1.1 500 Internal Server Error
Server: spray-can/1.3.3

當我移動的有效載荷爲模板，在收到我的測試的一部分，現在看起來是這樣的：
http()
.client("http://localhost:18082/cases")
.send()
.post()
.accept("application/json; charset=UTF-8")
.contentType("application/json")
.payload(new ClassPathResource("templates/travelrequest.json"));
//.payload(
// "{ "+
// "\"definition\": \"travelrequest.xml\", "+
// "\"name\": \"travelrequest\" "+
// "} "
//);
模板資源包含這樣的文字：
{
"definition": "travelrequest.xml",
"name": "travelrequest"
}
當運行該測試中，我接收不同的響應代碼：400。在我的Wireshark捕獲以下包：
Host: localhost:18082
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.3 (Java/1.8.0_121)
Accept-Encoding: gzip,deflate
?{
"definition": "travelrequest.xml",
"name": "travelrequest"
}HTTP/1.1 400 Bad Request
Server: spray-can/1.3.3

請注意，請求是以一個意外的問號開始的。此問號在Citrus輸出中不可見：
17:36:13,629 DEBUG client.HttpClient| Sending HTTP message to: 'http://localhost:18082/cases'
17:36:13,629 DEBUG client.HttpClient| Message to send:
{
"definition": "travelrequest.xml",
"name": "travelrequest"
}
17:36:13,630 DEBUG ingClientInterceptor| Sending Http request message
請注意前面的空格直接放在左括號之前。
這是一些特殊字符嗎？它爲什麼被添加到有效載荷中？有沒有合理的解釋？
