我目前正在尝试从petFinder https://github.com/helenuria/Petfinder-API获取一个api。但是，它没有按照教程中的说明返回预期的对象，不确定我是否可能使用react native提取了错误

以下是Im用于获取api的代码：

const PET_API = 'http://api.petfinder.com/pet.getRandom?key=' + 'key' + '&animal=cat&location=' + '34758' + '&output=basic&format=json&callback=?'

 getadopt = async () => {
    const permission = await Permissions.askAsync(Permissions.LOCATION)
    if (permission.status === 'granted') {
      const location = await Location.getcurrentPositionAsync()
      const url = PET_API
      const response = await fetch(url)
      //const data = await response.json()
      let res = JSON.stringify(response);



     console.log(response)
    }
  }

It however only returns the following object and not the object the tutorial states,am I fetching the API incorrectly? 

Response {
  "_bodyBlob": Blob {
    "_data": Object {
      "blobId": "C573AEBC-6977-4CA5-8E19-62EDE29A7836","name": "pet.getRandom","offset": 0,"size": 381,"type": "text/plain",},"_bodyInit": Blob {
