本實例是為了實現在管理后臺實現微信菜單的添加刪除管理。
1、首先我們需要新建一個數據庫表用于存放menu菜單項
可包含的字段有id、父類id、name、排序、是否顯示、類型（view、click）、鏈接、adddate
注意后臺存menu菜單數據時，parentid=-1為一級菜單，或parendid為一級菜單的id作為該一級菜單下的二級菜單
2、在設置菜單時需要向微信接口傳menujson字符串，所以要先拼接字符串，后臺定義一個creatmenu()

public bool creatmenu() { string menujson = ""; //這里默認parentid=-1為最外層菜單，isactive=1為顯示,responsetype=1為click類型 datatable dtamenu = service.selectdatatable("id, name, responsetype, jsonstr,url", "weixinmenu", " parentid=-1 and isactive=1 order by sort"); if (dtamenu.rows.count > 0) { menujson = "{\"button\":["; for (int i = 0; i < dtamenu.rows.count; i++) { datatable dtbmenu = service.selectdatatable("id, name, responsetype, jsonstr,url", wx, " parentid=" + dtamenu.rows[i]["id"].tostring() + " and isactive=1 order by sort"); if (dtbmenu.rows.count > 0) { menujson += "{\"name\":\"" + dtamenu.rows[i]["name"].tostring() + "\",\"sub_button\":["; for (int j = 0; j < dtbmenu.rows.count; j++) { if (convert.toint32(dtbmenu.rows[j]["responsetype"]) == 2) { menujson += "{\"type\":\"view\",\"name\":\"" + dtbmenu.rows[j]["name"].tostring() + "\",\"url\":\"" + dtbmenu.rows[j]["jsonstr"].tostring() + "\"},"; } else { menujson += "{\"type\":\"click\",\"name\":\"" + dtbmenu.rows[j]["name"].tostring() + "\",\"key\":\"eventkey_" + dtbmenu.rows[j]["id"].tostring() + "\"},"; } } menujson = menujson.trimend(','); menujson += "]},"; } else { //if (convert.toint32(dtamenu.rows[i]["responsetype"]) == 2) //{ menujson += "{\"type\":\"view\",\"name\":\"" + dtamenu.rows[i]["name"].tostring() + "\",\"url\":\"" + dtamenu.rows[i]["jsonstr"].tostring() + "\"},"; //} //else //{ // menujson += "{\"type\":\"click\",\"name\":\"" + dtamenu.rows[i]["name"].tostring() + "\",\"key\":\"eventkey_" + dtamenu.rows[i]["id"].tostring() + "\"},"; //} } dtbmenu.dispose(); } dtamenu.dispose(); menujson = menujson.trimend(','); menujson += "]}"; menujson = menujson.trim(); return requstzmtocreatment(menujson); } else { return false; } } |
3、獲取到menujson字符串后調用微信接口創建菜單，需先獲取assess token,有關assess token獲取可參考：獲取accesstoken
