how to PUT multiple query parameter in REST web service

问题

Do anyone know how to PUT multiple query parameter in REST web service? I have write using java.My curl sample is like this:

curl -X PUT http://localhost:8080/project/resources/user/directory/sub-directory?name=shareuser&type=Read -v

My program is :

@PUT
@Path("{user}/{directory:.+}")
public Response doshare(@PathParam("user")String name,
        @PathParam("directory")String dir,
        @QueryParam("name")String sharename,
        @QueryParam("type")String type){
    mongoDAOImpl impl=new mongoDAOImpl();
    Mongo mongo=impl.getConnection("127.0.0.1","27017");
    DB db=impl.getDataBase(mongo,"public");
    DBCollection coll=impl.getColl(db,name);
    DBCollection coll2=impl.getColl(db,"sharedb");
    shareDTO sharedto=new shareDTO();
    String authority=type.toLowerCase();
    if(authority.equals("rd")){
        sharedto.setAuthority("4");
    }else if(authority.equals("rw")){
        sharedto.setAuthority("12");
    }
    sharedto.setTargetuser(sharename);
    sharedto.setRealURI("/home/public/"+name+"/"+dir);
    sharedto.setIdentifier(name);
    sharedto.setParentURI("/home/public/"+sharename);
    boolean bool = false;
    sharefun=new sharefunction();
    if(sharefun.checksubfoldershared(coll, coll2, sharedto)){
        bool=sharefun.sharefiles(coll, coll2, sharedto);
    }else{
        System.out.println("Error");
    }
    // ...

But I only get the name query parameter.How to get or how to type in curl command in order to get all query parameter?

回答1:

Your code is fine - the problem is with the way you're invoking curl. When passing a URL to curl that contains a '&', you have to put quotes around the URL. Otherwise, the shell will interpret the stuff after the '&' as a separate command.

EDIT: My text is getting munged when I submit it as a comment. Here's what you need to do:

curl -X PUT 'http://localhost:8080/project/resources/user/directory/sub-directory?name=shareuser&type=Read' -v

回答2:

You could try handling this all as a multipart upload (the server-side details aren't standardized and you didn't say what framework you're using so I can't give more clues) but I question why you're having the user and permissions set (via any parameters) in the first place. Surely you'd be better off deriving the user to store as through inspecting the user's login credentials and using a default set of permissions that they can change later on? Nearly as cheap, and enormously simpler.

Have you tried using the -d option? e.g.

curl -X PUT -d "name=shareuser&type=Read" http://locahost:8080/project/resources/user/directory/sub-directory -v
