# response-rewrite
|
|||
|
|
|
|||
|
|
该插件支持修改上游服务返回的 body 和 header 信息。
|
|||
|
|
|
|||
|
|
使用场景：
|
|||
|
|
1、可以设置 `Access-Control-Allow-*` 等 header 信息，来实现 CORS (跨域资源共享)的功能。
|
|||
|
|
2、另外也可以通过配置 status_code 和 header 里面的 Location 来实现重定向，当然如果只是需要重定向功能，最好使用 [redirect](redirect-cn.md) 插件。
|
|||
|
|
|
|||
|
|
#### 配置参数
|
|||
|
|
|名字 |可选|说明|
|
|||
|
|
|------- |-----|------|
|
|||
|
|
|status_code |可选| 修改上游返回状态码|
|
|||
|
|
|body |可选| 修改上游返回的 `body` 内容，如果设置了新内容，header 里面的 content-length 字段也会被去掉|
|
|||
|
|
|headers |可选| 返回给客户端的 `headers`，这里可以设置多个。头信息如果存在将重写，不存在则添加。想要删除某个 header 的话，把对应的值设置为空字符串即可|
|

### 示例
|
|||
|
|
|
|||
|
|
#### 开启插件
|
|||
|
|
下面是一个示例，在指定的 route 上开启了 `response rewrite` 插件:
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
curl http://127.0.0.1:9080/apisix/admin/routes/1 -X PUT -d '
|
|||
|
|
{
|
|||
|
|
"methods": ["GET"],
|
|||
|
|
"uri": "/test/index.html",
|
|||
|
|
"plugins": {
|
|||
|
|
"response-rewrite": {
|
|||
|
|
"body": "{\"code\":\"ok\",\"message\":\"new json body\"}",
|
|||
|
|
"headers": {
|
|||
|
|
"X-Server-id": 3,
|
|||
|
|
"X-Server-status": "on"
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
},
|
|||
|
|
"upstream": {
|
|||
|
|
"type": "roundrobin",
|
|||
|
|
"nodes": {
|
|||
|
|
"127.0.0.1:80": 1
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
}'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
#### 测试插件
|
|||
|
|
基于上述配置进行测试：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
curl -X GET -i http://127.0.0.1:9080/test/index.html
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
如果看到返回的头部信息和内容都被修改了，即表示 `response rewrite` 插件生效了。

|||
