我正在尝试更新 Firebase 数据库中的一些数据。但是我无法让 updateAPI 函数正常工作。我相信这与 axios.put 有关，该 url 可能没有正确遍历数据？
我尝试更改 url，但最终出现 OPTIONS 和 CORS 错误，这意味着 url 不正确。
// API Function calls
async getAPI(){
const response = await axios.get('https://fir-test-euifhefibewif.firebaseio.com/todos.json')
console.log(response)
console.log(response.data)
}
async postAPI(){
const response = await axios.post('https://fir-test-euifhefibewif.firebaseio.com/todos.json', {name: notesAll})
console.log(response)
console.log(response.data)
}
async deleteAPI(){
const response = await axios.delete('https://fir-test-euifhefibewif.firebaseio.com/todos.json')
console.log(response)
console.log(response.data)
}
async updateAPI(){
const response = await axios.put('https://fir-test-euifhefibewif.firebaseio.com/todos/-LVYEw6KTltVoEkPeuxY/name/0', {note})
console.log(response)
console.log(response.data)
}
// Notes notesAll
const notesAll = [
{
"name": "user1",
"race": "human"
},
{
"name": "user2",
"race": "human"
},
{
"name": "user3",
"race": "human"
},
{
"name": "user4",
"race": "human"
},
{
"name": "user5",
"race": "human"
}
]
// Test data
const note = [
{
name: 'Test',
race: 'Test'
}
]
// Firebase database example
{
"todos": {
"-LVYIfktKR6fa6ish1aw": {
"name": [
{
"name": "user1",
"race": "human"
},
{
"name": "user2",
"race": "human"
},
{
"name": "user3",
"race": "human"
},
{
"name": "user4",
"race": "human"
},
{
"name": "user5",
"race": "human"
}
]
}
}
}
所有代码需要做的就是更新对象数组内的一些数据。
最佳答案
尝试:
async updateAPI(){
const response = await axios.put('https://fir-test-euifhefibewif.firebaseio.com/todos/-LVYEw6KTltVoEkPeuxY/name/0', note)
console.log(response)
console.log(response.data)
}
// Test data
const note = {
name: 'Test',
race: 'Test'
}
要使用 REST 写入 Firebase 数据库，URL 必须以 .json 结尾。所以:
url = yourUrl + ".json";
