一、跨域访问受限问题处理：
问题现象：
跨域访问问题
问题处理：
- 安装django-cors-headers:
sudo pip install django-cors-headers
- 配置文件修改：
diff --git a/Server/Server/settings.py b/Server/Server/settings.py
index 4657df3..feca1d7 100644

二、bootstrap-table接受的数据结构跟django返回不一致问题处理：
问题现象：
- bootstrap-table接受的数据结构：
# 不分页结构：
[
{
"id": 0,
"name": "Item 0",
"price": "$0"
},
{
"id": 1,
"name": "Item 1",
"price": "$1"
},
{
"id": 2,
"name": "Item 2",
"price": "$2"
}
]
# 分页结构：
{
"total": 200,
"rows": [
{
"id": 0,
"name": "Item 0",
"price": "$0"
},
{
"id": 1,
"name": "Item 1",
"price": "$1"
}
]
}
- django返回的数据结构：
{
"meta": {
"limit": 50,
"next": null,
"offset": 0,
"previous": null,
"total_count": 1
},
"objects": [
{
"resource_uri": "/api/v1/oplog/NATGW",
"time": "2017-03-10T15:01:19.645000",
"type": "NATGW",
"version": 11
}
]
}
问题处理：
查看bootstrap-table documentation可以发现有这样一个处理方法：
| Name | Attribute | Type | Default | Description |
|---|---|---|---|---|
| responseHandler | data-response-handler | Function | function(res) {return res;} | Before load remote data, handler the response data format, the parameters object contains: res: the response data. |
- 定制
responseHandler方法：
// table init 配置项：
responseHandler: tableInit.responseHandler,
// 具体实现：
tableInit.responseHandler = function (res) {
console.log('onLoadSuccess, res is:', res);
var response = {}
response['total'] = res.meta.total_count
response['rows'] = res.objects
console.log('responseHandler, response is:', response);
};
