在REST資源中接收空值

[英]Receiving null values in REST Resource

在通過帶有ajax的POST通過POST發送這兩個參數時,我一直接收空值(也嘗試過Poster):

@POST
@Path("/update")
@Produces(MediaType.APPLICATION_JSON)
public void update(String Path, String Content) {

updateURI(Path,Content);


    }

路徑: http//essam.ldm.io/stor...amblog/ChannelList/ch1/post2

內容: <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://crosscloud/mblog/Post>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://crosscloud/mblog/owner> <https://essam.ldm.io></https:>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://purl.org/dc/terms/created> <2013-03-06T16:41:18+0300^^http://www.w3.org/2001/XMLSchema#dateTime>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://rdfs.org/sioc/ns#content>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://crosscloud/mblog/Post>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://crosscloud/mblog/owner> <https://essam.ldm.io></https:>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://purl.org/dc/terms/created> <2013-03-06T16:41:18+0300^^http://www.w3.org/2001/XMLSchema#dateTime>. <http://essam.ldm.io/storage/essamblog/ChannelList/ch1/post2> <http://rdfs.org/sioc/ns#content>.

顯然,由於格式原因,我無法將它們作為@QueryParam@PathParam發送。

放上jQuery代碼是不安的,因為它既沒有與Poster一起退出wotk,但是在這里是:

function doUpdate(path, rdf)
        {
            var obj1 = {"path": path, "rdf": rdf};
            var sUrl = "http://localhost:8080/browsing/services/RDF/update";
            $.ajax({
                type: "POST",
                url: sUrl,
                contentType: "application/json; charset=utf-8",
                data: obj1,
                //dataType: "json",
                async: false,
                success: function (resp, status, xhr) {
                   $("#message").html("STATUS: " + xhr.status + " " + xhr.statusText + "\n" + resp);
                   $("#message").hide();
                   $("#login_message").html("<font color='green'><b>Record succesfully updated</b></font>d");
                },
                error: function(resp, status, xhr){
                    $("#message").html("ERROR: " + resp.status + " " + resp.statusText + "\n" + xhr);
                    $("#message").show();
                }
            });
        }

我做錯了什么?

謝謝,

您可以先對其進行編碼(即base64),然后再將其發送並在服務器上對其進行解碼,也可以將JSON用作請求參數。

例如,使用JSON。

@POST
@Path("/update")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public void update(PathContext ctx) {
    updateURI(ctx.getPath(),ctx.getContent());
}

@XmlRootElement
public class PathContext {
    private String path;
    private String content;

    public String getPath() {
        return path;
    }

    public void setPath(String path) {
        this.path = path;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

}

您的JSON看起來像;

{"path": somePath, "content": someContent}

希望能幫助到你。
