[GitHub] [apisix] kingmouse-yx opened a new issue, #6932: bug: In the rewrite phase, modifying the http request mode will cause multiple request calls
kingmouse-yx opened a new issue, #6932:
URL: https://github.com/apache/apisix/issues/6932
### Current Behavior
In the rewrite phase, modifying the http request mode will cause multiple request calls
I customized a plug-in, and in the rewrite phase, I rewritten the request method and uri_args of this request. Here is my code:
```lua
-- 将ng中的请求数据换成转换完成的数据
local req_data_uri_args_json = core.json.decode(req_data_format)
log.warn(type(req_data_uri_args_json))
ngx.req.set_method(ngx.HTTP_GET)
ngx.req.set_uri_args(req_data_uri_args_json)
log.warn("设置之后的请求方法：",ngx.req.get_method())
```
But when I tested it, I found that apisix would make multiple requests. At the same time, I found a lot of such request information in the access.log:

I want to ask why my operation causes such problems in the rewrite phase?
> Note: This doesn't happen every time(most of the time). Sometimes, after deleting the route and re-creating it, it may only initiate two requests, but sometimes it is normal
### Expected Behavior
I can modify it in rewite phase without triggering multiple calls

I use postman to verify my route. In postman, the default parameter of the host is < calculated when request is sent >.
The above situation will occur at this time. However, if you modify the host to a fixed value, it will not cycle many times and only return the request failure message.
