HTTPBuilder 查询参数答案

【问题描述】：

我正在尝试了解 HTTP Builder 的简化 GET。我成功完成了类似于 REST GET 请求的简单 GET 请求。

def client = new HTTPBuilder('http://pokeapi.co')
def resp = client.get(path: '/api/v1/pokemon/1')

static void main(String[] args){
    def h = new HTTP()
    print h.resp.name
}

我接下来要做的是向查询中添加参数。

def client = new HTTPBuilder('http://svcs.sandbox.ebay.com')
def resp = client.get(path: '/services/search/FindingService/v1',
                      contentType: TEXT,
                      query:[
                          'SECURITY-APPNAME': APP_ID,
                          'OPERATION-NAME':'findItemsByKeywords',
                          'SERVICE_VERSION':'1.0.0',
                          'RESPONSE-DATA-FORMAT':'JSON',
                          'callback':'_cb_findItemsByKeywords',
                          'REST-PAYLOAD': '',
                          'keywords':'iphone 3g',
                          'paginationInput.entriesPerPage': '3'])
}

当我打印 resp 时，我得到：

java.io.StringReader@16d871c0

参数的代码是否正确？还有我的输出有什么问题？

我的查询（当我通过浏览器运行时）产生

【问题讨论】：

已修复。 contentType 不应设置为 TEXT。

标签： groovy httpbuilder

【解决方案1】：

修复它。 contentType 不是TEXT。

【讨论】：

【解决方案2】：

您可以将 ContentType 设置为 TEXT 并且它可以工作。实际上，您会收到一个 java.io.StringReader，您可以将其转换为字符串。

import org.apache.commons.io.IOUtils;
...
String string = IOUtils.toString(reader);

重要！通过将 ContentType 设置为 TEXT，GET 方法将准确返回检索到的内容。如果您将 ContentType 设置为 JSON，则 GET 方法会自动将 JSON 响应解析为 LazyMap，这并不总是您想要的。
