QPX Express API返回400解析错误 [英] QPX Express API is returning 400 parse error

问题描述

我想使用Google QPX Express API中的数据，而我正在尝试设置一个非常基本的请求。
在demopage [1]上我复制了生成的JSON，如下所示：

I'd like to consume data from the Google QPX Express API and I'm trying to setting up a very basic request. On the demopage [1] I copied the generated JSON which looks as follows:

{
  "request": {
    "slice": [
      {
        "origin": "ZRH",
        "destination": "DUS",
        "date": "2014-12-02"
      }
    ],
    "passengers": {
      "adultCount": 1,
      "infantInLapCount": 0,
      "infantInSeatCount": 0,
      "childCount": 0,
      "seniorCount": 0
    },
    "solutions": 20,
    "refundable": false
  }
}

根据在线手册[2]基本请求具有以下结构：

According to the Online Manual [2] a basic request has the following structure:

https://www.googleapis.com/qpxExpress/v1/trips/search?key=your_API_key_here

所以我使用我在谷歌开发者控制台生成的API密钥插入了这段代码，但是重新

So I inserted this code using my API key which I generated in the google developers console, but the re

{
    "error": {
        "errors": [
            {
                "domain": "global",
                "reason": "parseError",
                "message": "Parse Error"
            }
        ],
        "code": 400,
        "message": "Parse Error"
    }
}

我的请求有什么问题？

推荐答案

您需要在请求中为Content-TypeHTTP标头指定值。在你的情况下application / json：

You need to specify a value for "Content-Type" HTTP header in your request. In you case "application/json" :

Content-Type：application / json

Content-Type: application/json
