React Native中的响应错误

Question

Here What I have got as a response

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

This is the Postman response

[
    [
        {
            "@id": 1,
            "name": "approval",
            "figure": "15",
            "type": "tile",
            "function": "auxxa.Approval",
            "url": "https://api.auxxa.com/BIMobile/GetApprovals"
        },
        {
            "@id": 1,
            "name": "returnCheque",
            "figure": "158,000.00",
            "type": "tile",
            "function": "auxxa.ReturnCheque",
            "url": "https://api.auxxa.com/BIMobile/GetApprovals"
        },
        {
            "@id": 1,
            "name": "notification",
            "figure": "12",
            "type": "tile",
            "function": "auxxa.Notification",
            "url": "https://api.auxxa.com/BIMobile/GetApprovals"
        }
    ]
]

Here I post my fetch method

fetch(url, {
  method: "GET"
})
  .then(response => response.json())
  .then(responseData => {
    //set your data here
    console.log("Landing Data " + responseData[0]);
  })
  .catch(error => {
    console.error(error);
  });

Could not find the actual issue.Please help me to sort out this issue.Thanks in advanced.

Answer 1

You are getting an array inside an array as response. Try accessing the first entry in each array and it should work.

You should also not use + with a string and an array. Log them separately instead with , :

fetch(url)
  .then(response => response.json())
  .then(responseData => {
    console.log("Landing Data", responseData[0][0]);
  })
  .catch(error => {
    console.error(error);
  });

Answer 2

make it , instead of + .

console.log("Landing Data " , responseData[0]);

It will just print the data, but you will get whole idea of your responce

Answer 3

try this:

console.log("Landing Data", responseData[0][0]);
