关于okhttp拦截器添加公共参数和response读取后不能返回的解决办法

Request originalRequest = chain.request();
Request request = null;
Map map = new HashMap<>();

 String method = originalRequest.method();//获取请求方法
 if(method.equals("GET")){//添加参数
  HttpUrl modifiedUrl = originalRequest.url().newBuilder()
 .addQueryParameter("channel", CHANNEL)
 .addQueryParameter("sign", sign)
 .build();
  request = originalRequest.newBuilder().url(modifiedUrl).build();//构建request
  Response response = chain.proceed(request);//进行网络请求并获得返回结果
  String content = response.body().string();//拿到返回结果，进行分析
 
MediaType mediaType = response.body().contentType();//获取返回结果的tupe
return response.newBuilder()//生成新的response返回，网络请求的response如果取出之后，直接返回将会抛出异常
  .body(ResponseBody.create(mediaType, content))
  .build(); 
 }else if(method.equals("POST")){
  if (originalRequest.body() instanceof FormBody) {
FormBody.Builder bodyBuilder = new FormBody.Builder();
FormBody formBody = (FormBody) originalRequest.body();
formBody = bodyBuilder //POST方法添加参数
  .add("channel", CHANNEL)
  .add("sign", sign)
  .build();
request = originalRequest.newBuilder().post(formBody).build();
Response response = chain.proceed(request);
String content =  response.body().string();

 MediaType mediaType = response.body().contentType();
 return response.newBuilder()
.body(ResponseBody.create(mediaType, content))
.build();
}
  }
 }
 return chain.proceed(originalRequest);
