Golang GenNodes Examples

Example #1

File: rule.go Project: bluefchen/studygolang

func ModifyRuleHandler(rw http.ResponseWriter, req *http.Request) {
	var data = make(map[string]interface{})

	if req.PostFormValue("submit") == "1" {
		user, _ := filter.CurrentUser(req)

		errMsg, err := service.ModifyTopic(user, req.PostForm)
		if err != nil {
			data["ok"] = 0
			data["error"] = errMsg
		} else {
			data["ok"] = 1
			data["msg"] = "修改成功"
		}
	} else {
		topic, replies, err := service.FindTopicByTid(req.FormValue("tid"))

		if err != nil {
			rw.WriteHeader(http.StatusInternalServerError)
			return
		}

		// 设置内容模板
		req.Form.Set(filter.CONTENT_TPL_KEY, "/template/admin/topic/modify.html")
		data["topic"] = topic
		data["replies"] = replies
		data["nodes"] = service.GenNodes()
	}

	filter.SetData(req, data)
}

Example #2

File: topic.go Project: bluefchen/studygolang

// 修改主题

		}
		fmt.Fprint(rw, `{"ok": 0, "error":"内部服务错误！"}`)
		return
	}
	fmt.Fprint(rw, `{"ok": 1, "data":""}`)
}

Example #3

File: topic.go Project: bluefchen/studygolang

// 社区帖子列表页
// uri: /topics{view:(|/popular|/no_reply|/last)}
func TopicsHandler(rw http.ResponseWriter, req *http.Request) {
	nodes := service.GenNodes()
	// 设置内容模板
	page, _ := strconv.Atoi(req.FormValue("p"))
	if page == 0 {

	}
	vars := mux.Vars(req)
	order := ""
	where := ""
	view := ""

	case "/no_reply":
		view = "no_reply"
		where = "lastreplyuid=0"
	case "/last":
		view = "last"
		order = "ctime DESC"
	}

	topics, total := service.FindTopics(page, 0, where, order)
	pageHtml := service.GetPageHtml(page, total, req.URL.Path)
	req.Form.Set(filter.CONTENT_TPL_KEY, "/template/topics/list.html")
	// 设置模板数据
	filter.SetData(req, map[string]interface{}{"activeTopics": "active", "topics": topics, "page": template.HTML(pageHtml), "nodes": nodes, "view": view})
}

Example #4
