[英]HTTP Post method using curl to post data to localhost failed
我正在嘗試使用HTTP GET方法:
curl http://localhost:8888/_ah/api/birra/v1/beer
它正在返回我正常和預期的當前列表:
{
"items" : [ {
"id" : "1",
"beerName" : "Bud"
}, {
"id" : "2",
"beerName" : "Steve"
}, {
"id" : "3",
"beerName" : "Ankur"
} ]
}
但是當我這樣做HTTP POST時:
curl -X POST -H "Content-Type: application/json" -H "Accept:application/json" -d "{\"beerName\": \"asdf\"}" http://localhost:8888/_ah/api/birra/v1/beer
它給我的錯誤是:
{
"error" : {
"message" : "javax.jdo.JDOFatalInternalException: The key value passed to construct a SingleFieldIdentity of type \"class javax.jdo.identity.LongIdentity\" for class \"class com.samples.Beer\" is null.\nNestedThrowables:\norg.datanucleus.exceptions.NucleusException: The key value passed to construct a SingleFieldIdentity of type \"class javax.jdo.identity.LongIdentity\" for class \"class com.samples.Beer\" is null.",
"code" : 503,
"errors" : [ {
"domain" : "global",
"reason" : "backendError",
"message" : "javax.jdo.JDOFatalInternalException: The key value passed to construct a SingleFieldIdentity of type \"class javax.jdo.identity.LongIdentity\" for class \"class com.samples.Beer\" is null.\nNestedThrowables:\norg.datanucleus.exceptions.NucleusException: The key value passed to construct a SingleFieldIdentity of type \"class javax.jdo.identity.LongIdentity\" for class \"class com.samples.Beer\" is null."
} ]
}
}
我目前正在研究Google開發人員提供的Google Cloud Endpoints示例: Cloud Endpoint
我正在使用Eclipse IDE和在Jetty上運行的服務器localhost。
有解決方案嗎
使用雙引號而不是單引號。 從Windows運行時會發生此類錯誤。 這就是它說couldn't resolve host
。
curl -H "Content-Type: application/json" -d "{\"beerName\": \"bud\"}" http://localhost:8888/_ah/api/birra/v1/beer
