问题:
Using the jax-rs(Jersey) I am try to implement a POST request that take a list of JSON object
//The resource look like this @Path("/path") @POST @Consumes(MediaType.APPLICATION_JSON) public void setJsonl(List<SomeObj> test) { //do work System.out.println(test); } //The class to define the json structure @XmlRootElement public class SomeObj{ private String tag; private String value; public String getTag() { return tag; } public void setTag(String tag) { this.tag = tag; } public String getValue() { return value; } public void setValue(String value) { this.value = value; } }
how ever when I try to test the REST api using curl I always get a "bad request" error, am I missing something here?
curl -X POST -H "Content-Type: application/json" -d '{"SomeObj":[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]}' http://{host_name}:8080/path_to_resource
回答1:
If you don't mind changing the signature of your method:
import org.json.JSONArray; //The resource look like this @Path("/path") @POST @Consumes(MediaType.APPLICATION_JSON) public void setJsonl(String array){ JSONArray o = new JSONArray(last_data); System.out.println(o.toString());

a late answer but may be helpful for others Post this:
[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]
Because by sending this:
{"SomeObj":[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]}
you are posting an object with a single 'SomeObj' named property. you are not posting an array
回答3:
Try wrapping your JSON array inside an object like:
@XmlRootElement public class SomeObjListWrapper { private List<SomeObj> list; // getters and setters } curl -X POST -H "Content-Type: application/json" -d '{"list":[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]}' http://{host_name}:8080/path_to_resource

On the server side:
import _root_.org.codehaus.jettison.json.{JSONArray, JSONObject} @POST @Path("/wants-json-array") @Consumes(Array(MediaType.APPLICATION_JSON)) def wantsJSONArray(array: JSONArray): Response = { // here's your array }
And on the client side:
$.ajax( { type: "GET", url: '/your-web-service/wants-json-array', data: JSON.stringify(THEARRAYYOUARESENDINGTOTHESERVER), contentType: "application/json", dataType: "json", processData: false });
