django抛出异常然后在axios里处理

 

1.views.py代码

@csrf_exempt
def get_selectdata_by_sql(request):current = request.GET.get("current", 1)size = request.GET.get("size", 0)limit_size=50try:res_list = []request_dict = json.loads(request.body)# print(request_dict)runsql = request_dict.get("sql").replace(";", "") + ' limit  '+str(limit_size)print('runsql=', runsql)# 有值才处理with connection.cursor() as cursor:cursor.execute(runsql)col_names = [desc[0] for desc in cursor.description]print('col_names=', col_names)row = cursor.fetchall()rowList = []for list in row:tMap = dict(zip(col_names, list))rowList.append(tMap)# 总数total = rowList.__len__()if current and size:end = int(current) * int(size)start = (int(current) - 1) * int(size)rowList = rowList[start:end]for user in rowList:res_list.append(user)res = {"columns": col_names,"rows": res_list,"total": total,"result": True}return JsonResponse(res, safe=False)
    except Exception as e:#捕获异常并返回错误信息return JsonResponse({'error': str(e)}, status=400)
