RESTful Webservice无法正确处理Request Method [英] RESTful Webservice does not handle Request Method properly

问题描述

我正在从多个RESTful Web Service方法中检索值。
在这种情况下，由于请求方法存在问题，两种方法会相互干扰。

I am retreiving values from multiple RESTful Web Service methods. In this case two methods interfere with one another, due to a problem with the Request Method.

@GET
@Path("/person/{name}")
@Produces("application/xml")
public Person getPerson(@PathParam("name") String name) {
    System.out.println("@GET /person/" + name);
    return people.byName(name);
}

@POST
@Path("/person")
@Consumes("application/xml")
public void createPerson(Person person) {
    System.out.println("@POST /person");
    System.out.println(person.getId() + ": " + person.getName());
    people.add(person);
}

当我尝试使用以下代码调用createPerson（）方法时，我的Glassfish服务器将导致@GET / person / 我试图在上创建一个人的名称。这意味着@GET方法被调用，即使我没有发送{name}参数（如代码中所示）。

As I try to call the createPerson() method using the following code, my Glassfish Server will result in "@GET /person/ the name I'm trying to create a person on". Which means the @GET method is called, even though I did not send a {name} parameter (as you can see in the code).

URL url = new URL("http://localhost:8080/RESTfulService/service/person");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "application/xml");
connection.setDoOutput(true);
marshaller.marshal(person, connection.getOutputStream());

我知道这需要大量挖掘我的代码，但我在这方面做错了什么case？

I know this is asking a lot of digging in my code, but what am I doing wrong in this case?

UPDATE

因为createPerson是一个空白，我无法处理connection.getInputStream（）。
这实际上似乎导致我的服务没有处理请求。

Because createPerson is a void, I do not handle a connection.getInputStream(). This actually seems to result in the request not being handled by my Service.

但实际请求是在connection.getOutputStream（）上发送的，对吧？

But the actual request is sent on the connection.getOutputStream(), right?

更新2

RequestMethod确实有效，只要我处理一个具有返回值的方法，因此是connection.getOutputStream（）。当我尝试调用void而不处理connection.getOutputStream（）时，服务将不会收到任何请求。

The RequestMethod does work, as long as I handle a method with a return value and thus connection.getOutputStream(). When I try calling a void and thus not handling connection.getOutputStream(), the Service will not receive any request.

推荐答案

你应设置Content-Type而不是Accept标题。 Content-Type指定发送给收件人的媒体类型，而Accept是关于客户端接受的媒体类型。有关标题的更多详细信息，请此处。

You should set the "Content-Type" instead of "Accept" header. Content-Type specifies the media type sent to the recipient, while Accept is about the media type accepted by the client. More details on headers are here.

这是Java客户端：

public static void main(String[] args) throws Exception {
    String data = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><person><name>1234567</name></person>";
    URL url = new URL("http://localhost:8080/RESTfulService/service/person");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type", "application/xml");

    connection.setDoOutput(true);
    connection.setDoInput(true);        

    OutputStreamWriter wr = new OutputStreamWriter(connection.getOutputStream());
    wr.write(data);
    wr.flush();

    // Get the response
    BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    wr.close();
    rd.close();

    connection.disconnect();
}

以下是使用curl的相同内容：

Here is the same using curl:

curl -X POST -d @person --header "Content-Type:application/xml" http://localhost:8080/RESTfulService/service/person

，其中person是包含xml的文件：

, where "person" is a file containing the xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><person><name>1234567</name></person>
