I write a plugin to check it:
```
function _M.access(conf, ctx)
local req_body, err = core.request.get_body()
if not req_body then
return 503, {message = err}
end
local decoded, err = core.json.decode(req_body)
if not decoded then
return 503, {message = err}
end
ngx.log(ngx.WARN, "get key ", decoded.key)
return 200, decoded.key
end
```
And request it with this:
```
#!/usr/bin/env python
# coding: utf-8
# sudo pip install requests
import requests
resp = requests.put("http://127.0.0.1:9080/test";, json={
"key": "key",
"value": "12345" * (1024 * 1024)
})
print(resp.status_code)
print(resp.text)
```
Then I get the result successfully:
```

```
The wrong is in somewhere else.
