Groovy HttpBuilder - 获取失败响应的正文

Question

我正在尝试使用 Groovy HTTPBuilder 编写一个集成测试，该测试将验证正文中是否返回正确的错误消息以及 HTTP 409 状态消息。但是，我无法弄清楚如何在失败的情况下实际访问 HTTP 响应的正文。

http.request(ENV_URL, Method.POST, ContentType.TEXT) {
    uri.path = "/curate/${id}/submit"
    contentType = ContentType.JSON
    response.failure = { failresp_inner ->
        failresp = failresp_inner
    }
}

then:
assert failresp.status == 409
// I would like something like 
//assert failresp.data == "expected error message"

这是来自服务器的 HTTP 响应的样子:

2013-11-13 18:17:58,726 DEBUG  wire - << "HTTP/1.1 409 Conflict[\r][\n]"
2013-11-13 18:17:58,726 DEBUG  wire - << "Date: Wed, 13 Nov 2013 23:17:58 GMT[\r][\n]"
2013-11-13 18:17:58,726 DEBUG  wire - << "Content-Type: text/plain[\r][\n]"
2013-11-13 18:17:58,726 DEBUG  wire - << "Transfer-Encoding: chunked[\r][\n]"
2013-11-13 18:17:58,727 DEBUG  wire - << "[\r][\n]"
2013-11-13 18:17:58,728 DEBUG  wire - << "E[\r][\n]"
2013-11-13 18:17:58,728 DEBUG  wire - << "expected error message"
2013-11-13 18:17:58,728 DEBUG  wire - << "[\r][\n]"
2013-11-13 18:17:58,728 DEBUG  wire - << "0[\r][\n]"
2013-11-13 18:17:58,728 DEBUG  wire - << "[\r][\n]"

我最近在尝试使用 Spock 对我的 REST 端点进行集成测试时遇到了这个问题。我使用 Sam 的回答作为灵感，并最终对其进行了改进，以便继续利用 HttpBuilder 提供的自动转换。折腾了一段时间后，我有了一个聪明的想法，就是将成功处理程序闭包分配给失败处理程序，以标准化行为，而不管返回什么状态代码。

client.handler.failure = client.handler.success

它的一个例子:

...

import static org.apache.http.HttpStatus.*

...

private RESTClient createClient(String username = null, String password = null) {
    def client = new RESTClient(BASE_URL)
    client.handler.failure = client.handler.success

    if(username != null)
        client.auth.basic(username, password)

    return client
}

...

def unauthenticatedClient = createClient()
def userClient = createClient(USER_USERNAME, USER_PASSWORD)
def adminClient = createClient(ADMIN_USERNAME, ADMIN_PASSWORD)

...

def 'get account'() {
    expect:
    // unauthenticated tries to get user's account
    unauthenticatedClient.get([path: "account/$USER_EMAIL"]).status == SC_UNAUTHENTICATED

    // user gets user's account
    with(userClient.get([path: "account/$USER_EMAIL"])) {
        status == SC_OK
        with(responseData) {
            email == USER_EMAIL
            ...
        }
    }

    // user tries to get user2's account
    with(userClient.get([path: "account/$USER2_EMAIL"])) {
        status == SC_FORBIDDEN
        with(responseData) {
            message.contains(USER_EMAIL)
            message.contains(USER2_EMAIL)
            ...
        }
    }

    // admin to get user's account
    with(adminClient.get([path: "account/$USER_EMAIL"])) {
        status == SC_OK
        with(responseData) {
            email == USER_EMAIL
            ...
        }
    }
}
