无法通过Java从mashape访问gaana API [英] unable to access gaana api via java from mashape

问题描述

我正在使用mashape API试图从Java端访问gaana API
我是从本地主机尝试。但是，我得到的问题，同时试图连接gaana API。
下面是我的休息服务的一个我的code（我用弹簧的安全性和java8）。我BTECH-CSE最后一年的学生。

i am trying to access gaana api from java side by using mashape api i am trying from a localhost. but, i am getting issues while trying to connect gaana api. Below is my code in one of my rest service ( I am using spring-security and java8). I am Btech-CSE final year student.

@RestController
@RequestMapping("/api/ideas")
public class IdeaController {
    @RequestMapping(method = RequestMethod.GET)
    public void invokeGaanaAPI() throws UnirestException {
        System.out.println("hello");
     // These code snippets use an open-source library.
//      HttpServletResponse<JsonNode> response =

        Unirest.get("https://community-gaana.p.mashape.com/index.php?subtype=most_popular&type=song")
        .header("X-Mashape-Key", "iWEvla5JyCmshafdpHdjoSdtPsHPp1Ily4qjsnCEiVxbQsY5tn")
        .header("Accept", "application/json")
        .asJson();

        Unirest.get("https://community-gaana.p.mashape.com/user.php?type=registrationtoken")
                .header("X-Mashape-Key", "iWEvla5JyCmshafdpHdjoSdtPsHPp1Ily4qjsnCEiVxbQsY5tn")
                .header("Accept", "application/json")
                .asJson();
        System.out.println("hello");
    }
}

我需要帮助在这种情况下继续进行。任何形式的帮助是为我好。我得到的数据为空。因此，JSON的转换抛出空指针异常。
我热衷于做这个项目。

I need help to proceed in this situation. any kind of help is fine for me. i am getting data as null. so, json conversion is throwing null pointer exception. I am passionate to do this project.

推荐答案

您的数据空因为你还没有分配 Unirest.get （）返回值任何东西。

Your data is null because you haven't assigned the Unirest.get() return value to anything.

请使用该 API 阅读文档。
