提问by LOK
Using the jax-rs(Jersey) I am try to implement a POST request that take a list of JSON object
使用 jax-rs(Jersey) 我尝试实现一个采用 JSON 对象列表的 POST 请求
//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?
当我尝试使用 curl 测试 REST api 时，我总是收到“错误请求”错误，我是否在这里遗漏了什么？
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

If you don't mind changing the signature of your method:
如果您不介意更改方法的签名：
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:
一个迟到的答案，但可能对其他人有帮助 发布这个：
[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]
[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]
Because by sending this:
因为通过发送这个：
{"SomeObj":[{"tag":"abc", "value":"ghi"},{"tag":"123", "value":"456"}]}
{"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
您正在发布具有单个“SomeObj”命名属性的对象。你没有发布一个数组

Try wrapping your JSON array inside an object like:
尝试将您的 JSON 数组包装在一个对象中，例如：
@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:
在服务器端：
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:
而在客户端：
$.ajax(
{
type: "GET",
url: '/your-web-service/wants-json-array',
data: JSON.stringify(THEARRAYYOUARESENDINGTOTHESERVER),
contentType: "application/json",
dataType: "json",
processData: false
});
