SpringCloud 从文件传递值

从版本1.2.0开始，您可以传递文件中的值。假设您在我们的项目中拥有以下资源。

└── src
    └── test
        └── resources
            └── contracts
                ├── readFromFile.groovy
                ├── request.json
                └── response.json

进一步假设您的合同如下：

Groovy DSL。

import org.springframework.cloud.contract.spec.Contract

Contract.make {
	request {
		method('PUT')
		headers {
			contentType(applicationJson())
		}
		body(file("request.json"))
		url("/1")
	}
	response {
		status OK()
		body(file("response.json"))
		headers {
			contentType(applicationJson())
		}
	}
}

YAML。 

request:
  method: GET
  url: /foo
  bodyFromFile: request.json
response:
  status: 200
  bodyFromFile: response.json

进一步假设JSON文件如下：

request.json

{
  "status": "REQUEST"
}

response.json

{
  "status": "RESPONSE"
}

当进行测试或存根生成时，文件的内容将传递到请求或响应的主体。文件名必须是相对于合同所在文件夹的位置的文件。

如果您需要以二进制格式传递文件的内容，则足以使用Groovy DSL中的fileAsBytes方法或YAML中的bodyFromFileAsBytes字段。

Groovy DSL。 

import org.springframework.cloud.contract.spec.Contract

Contract.make {
	request {
		url("/1")
		method(PUT())
		headers {
			contentType(applicationOctetStream())
		}
		body(fileAsBytes("request.pdf"))
	}
	response {
		status 200
		body(fileAsBytes("response.pdf"))
		headers {
			contentType(applicationOctetStream())
		}
	}
}

YAML。 

request:
  url: /1
  method: PUT
  headers:
    Content-Type: application/octet-stream
  bodyFromFileAsBytes: request.pdf
response:
  status: 200
  bodyFromFileAsBytes: response.pdf
  headers:
    Content-Type: application/octet-stream

每当要使用HTTP和消息传递的二进制有效负载时，都应使用此方法。
