如何在rest api自动化中处理分页

Question

如何在 REST API 中处理分页？

public getMethodForCenter(String baseUrl, String endpoint) {
    HttpURLConnection openConnection = new URL(baseUrl + endpoint).openConnection()
    def token = postAuthorization(Users.username, Users.password)
    openConnection.setRequestMethod("GET")
    openConnection.setRequestProperty("Authorization", "Bearer " + token)
    if(openConnection.getResponseCode() == 200) {
        assert openConnection.getResponseCode() == 200
        def responseBody = openConnection.getInputStream().getText()
        def parsedJson = slurper.parseText(responseBody)
        assert parsedJson.statusCode == 200
        return parsedJson
    } else {
        assert openConnection.getResponseCode() != 200
        def responseBody = openConnection.getErrorStream().getText()
        def parsedJson = slurper.parseText(responseBody)
        assert parsedJson.statusCode == 200
        return parsedJson
    }
}

我必须测试分页，但如何处理和创建分页链接？例如，我有 5 个可选字段：id、createDate、modifiedDate、Name 等。 我正在考虑使用 if/else 语句自己创建链接，但是会有太多变化，我认为这不是正确的方法。 这就是我对一个领域的意思： 添加一个值 - getMethodForCenter(String baseUrl, String endpoint, String name) 然后做一个 if/else 语句：

if(name == null) {
  HttpURLConnection openConnection = new URL(baseUrl + endpoint).openConnection
} else {
  HttpURLConnection openConnection = new URL(baseUrl + endpoint + "?Name=${name}"
}

**编辑：**另一种方法是添加String path并自己传递路径

如果您申请http-builder，您的代码将减少到最低限度，因此您将能够轻松测试所有参数组合。

通常分页由可选的请求参数表示，例如max、offset、first 等。

话虽如此，您的代码可以归结为：

def http = HttpBuilder.configure {
    request.uri = baseUrl + enpoint
    request.headers.Authorization = "Bearer $token"
    request.contentType = 'application/json'
}

def paginationCombos = [ [ 10, 0 ], [ 10, 1], [ 20, 1 ] ] // etc

paginationCombos.each{ pair ->
  def (max, offset) = pair
  def json = http.get {
    request.uri.query = [ max:max, offset:offset ] // here you can add filters
    response.success{ FromServer fs, Object jsonBody ->
        assert jsonBody.statusCode == 200
        jsonBody
    }
  }
}
