来自CURL的成功JSON响应 - 没有来自RESTClient / HttpRequester的JSON响应

Question

我正在尝试修复服务器端问题（我认为） - 我必须要做的唯一真正的线索是当我从终端使用curl时 - 我得到了正确的JSON响应。当我使用RESTClient或HttpRequester时（这些都是浏览器的插件来测试请求）我不会得到一个空的但成功的回复。这一切都与我正在创建一个iOS应用程序的事实相关，并且在该应用程序中 - 当我尝试使用RESTClient或HttpRequester发出请求时，我遇到了相同的结果 - 没有JSON ，但成功的请求。

我在想如果我可以获得使用RESTClient或HttpRequester的请求，那么它将适用于我的iOS应用（我的iOS应用也存在接收空JSON响应的问题）。

我正在为我的服务器端代码（PHP）寻找调试策略 - 如果有人想看到它的任何一个请问 - 我想知道这是否可以通过更改设置来修复我的php.ini文件。

非常感谢任何帮助。
