echo-body

A test image for checking http body in e2e test suites.

将收到的request body放进response body中返回，request与response的ContentType保持一致，目前支持"application/json"，"application/x-www-form-urlencoded"，"multipart/form-data", "text/plain"

其他功能：

1. 支持response body附带ingress信息，header中设置X-Echo-Ingress-Info为true可开启，（ContentType需为application/json，application/x-www-form-urlencoded或multipart/form-data
2. 支持response body附带自定义数据，header中通过X-Echo-Set-Body字段进行设置，（ContentType需为application/json，application/x-www-form-urlencoded或multipart/form-data

使用：

1. echo-body镜像构建

docker build -t <your_registry_hub>/echo-body:1.5.0 -f ./Dockerfile .

2. k8s中容器部署

kubectl apply -f ./test-env.yaml

3. k8s中运行

4. 测试 见测试代码

备注：

1. 支持多种类型body，如"application/json"（已支持），"application/x-www-form-urlencoded"，"multipart/form-data"
2. 目前只测试了body为两层嵌套的情况，即map[string][]string，更多层嵌套的情况暂未测试
