Chainlink外部适配器[请求失败，状态码为400]

Question

我正在尝试学习链接外部适配器，我是新手。

有可能得到以下方面的帮助吗?我的适配器代码不工作，告诉我使用了无效的参数。

我试图在coinpaprika上点击以下API:

https://api.coinpaprika.com/v1/price-converter?base_currency_id=link-chainlink& quote_currency_id = usdt-tether&数量= 1

下面是我在nodejs中的适配器代码

const customError = (data) => {
if (data.Response === 'Error') return true
return false
}
const customParams = {
base: ['base', 'from', 'coin'],
quote: ['quote', 'to', 'market'],
amount: ['amount', 'qty', 'num'],
endpoint: false
}
const createRequest = (input, callback) => {
const validator = new Validator(callback, input, customParams)
const jobRunID = validator.validated.id
const endpoint = validator.validated.data.endpoint || 'price-converter'
const url = `https://api.coinpaprika.com/v1/${endpoint}`
const base_currency_id = validator.validated.data.base.toUpperCase()
const quote_currency_id = validator.validated.data.quote.toUpperCase()
const amount = validator.validated.data.amount.toUpperCase()

const params = {
base_currency_id,
quote_currency_id,
amount
}
const config = {
url,
params
}
Requester.request(config, customError)
.then(response => {
response.data.result = Requester.validateResultNumber(response.data, [amount])
callback(response.status, Requester.success(jobRunID, response))
})
.catch(error => {
callback(500, Requester.errored(jobRunID, error))
})
}

这是我的CURL调用:

curl -X POST -H "content-type:application/json" "http://localhost:8080/" --data '{ "id": 0, "data": { "base": "chainlink", "quote": "usdt-tether","amount": "1" } }'

这是获取

时的服务器错误输出

id: 0,
data: { base: 'chainlink', quote: 'usdt-tether', amount: '1' }
}

更新

好像使用了错误的CURL参数，应该是link-chainlink而不是chainlink

POST Data:  {
id: 0,
data: { from: 'link-chainlink', to: 'usdt-tether', qty: '1' }
}
{"message":"Received response: {"base_currency_id":"link-chainlink","base_currency_name":"Chainlink","base_price_last_updated":"2021-07-25T10:40:07Z","quote_currency_id":"usdt-tether","quote_currency_name":"Tether","quote_price_last_updated":"2021-07-25T10:40:07Z","amount":1,"price":16.917664107956217}","level":"info","timestamp":"2021-07-25T10:41:07.797Z"}
{"message":"Result could not be found in path","level":"error","timestamp":"2021-07-25T10:41:07.797Z"}
Result:  {
jobRunID: 0,

现在我需要弄清楚如何正确传递结果

Answer 1

我修复了。2 .传递错误参数导致结果错误

改成:

response.data.result = Requester.validateResultNumber(response.data, ['price'])
