Bug?

[forrestsun]

I define a struct File include file array.Cpu and memory is 100% when run this program.

I find if File struct not include []File the program is right.But I can't find proberlem point :(

type File struct {
    Id, Name   string
    HitoryFile []File
}

type FileService struct {
    // normally one would use DAO (data access object)
    files map[string]File
}

func (f FileService) Register() {
    ws := new(restful.WebService)
    ws.
        Path("/files").
        Consumes(restful.MIME_XML, restful.MIME_JSON).
        Produces(restful.MIME_JSON, restful.MIME_XML) // you can specify this per route as well

    ws.Route(ws.GET("/{file-id}").To(f.findFile).
        // docs
        Doc("get a file").
        Param(ws.PathParameter("file-id", "identifier of the file").DataType("string")).
        Writes(File{})) // on the response
    restful.Add(ws)
}

// GET http://localhost:8080/users/1
//
func (f FileService) findFile(request *restful.Request, response *restful.Response) {
    id := request.PathParameter("file-id")
    file := f.files[id]
    if len(file.Id) == 0 {
        response.WriteErrorString(http.StatusNotFound, "File could not be found.")
    } else {
        response.WriteEntity(file)
    }
}

func main() {
    f := FileService{map[string]File{}}
    f.Register()

    // Optionally, you can install the Swagger Service which provides a nice Web UI on your REST API
    // You need to download the Swagger HTML5 assets and change the FilePath location in the config below.
    // Open http://localhost:8080/apidocs and enter http://localhost:8080/apidocs.json in the api input field.
    config := swagger.Config{
        WebServices:    restful.RegisteredWebServices(), // you control what services are visible
        WebServicesUrl: "http://localhost:8080",
        ApiPath:        "/apidocs.json",

        // Optionally, specifiy where the UI is located
        SwaggerPath:     "/apidocs/",
        SwaggerFilePath: "./apiview"}
    swagger.InstallSwaggerService(config)

    log.Printf("start listening on localhost:8080")
    log.Fatal(http.ListenAndServe(":8080", nil))
}

So you defined a recursive data structure. Does the problem only happen when asking for the user interface, i.e. when the Swagger model is constructed? I will create a test to verify that recursive structures are handled properly just in case.

I just created a test that confirms your problem and it is indeed related to creating a Swagger Model from your datastructure.
