zengxp0605 opened a new issue #2731:
URL: https://github.com/apache/incubator-shenyu/issues/2731
### Is there an existing issue for this?
- [X] I have searched the existing issues
### Current Behavior
The GET request header set `content-type:
application/x-www-form-urlencoded`, RpcParamTransformPlugin will get body from
HttpRequest, but in GET requset the body is empty, the parameters is in url
query part.
The code is in the `RpcParamTransformPlugin.java`
```java
if (MediaType.APPLICATION_FORM_URLENCODED.isCompatibleWith(mediaType)) {
return formData(exchange, request, chain);
}
...
private Mono<Void> formData(final ServerWebExchange exchange, final
ServerHttpRequest serverHttpRequest, final ShenyuPluginChain chain) {
return Mono.from(serverHttpRequest.getBody()
.flatMap(map -> {
String param = resolveBodyFromRequest(map);
LinkedMultiValueMap linkedMultiValueMap;
try {
linkedMultiValueMap =
BodyParamUtils.buildBodyParams(URLDecoder.decode(param,
StandardCharsets.UTF_8.name()));
} catch (UnsupportedEncodingException e) {
return Flux.error(e);
}
exchange.getAttributes().put(Constants.PARAM_TRANSFORM,
HttpParamConverter.toMap(() -> linkedMultiValueMap));
return chain.execute(exchange);
}));
}
```
### Expected Behavior
The GET request header set `content-type:
application/x-www-form-urlencoded`, RpcParamTransformPlugin can get parameters
from url query.
