参数值未定义,如何从变量中添加axios中的参数"/>
有没有一种方法可以从api调用API以表达axios中的参数值未定义,如何从变量中添加axios中的参数
**我尝试将参数传递给我的路由,然后将该参数传递给带有URL的变量axios
。如果我删除了params对象,而是将参数硬编码在url中,则请求成功。
我正在尝试发布问题,但是我的话很少,代码太多。我不知道如何解决这个问题,因此说明足以解决这个问题。我已经尽我所能解释了它。代码可以说明很多事情。谢谢。
const axios = require("axios");
dotenv.config();
const Url = "";
exports.getLocation = (req, res, next) => {
const country = req.body.countryCode;
axios
.get(Url, {
params: {
countryCode: country}
,headers: {'DHL-API-Key': process.env.LOCATOR_API_KEY}})
.then(function (response) {
console.log(response.data);
})
.catch(function (error) {
console.log(error);
});
};```

回答如下:这是从axios版本0.19开始的重大更改。如果您想向请求添加参数,则必须通过拦截器将其传递。例如:
const axios = require('axios');
// api openexchange
const oexchange = axios.create({
baseURL: 'https://openexchangerates/api/',
timeout: parseInt(process.env.TIMEOUTEXTERNALREQUEST)
})
oexchange.interceptors.request.use((config) => {
config.params = config.params || {};
config.params.app_id = process.env.OPENEXCHANGEAPITOKEN // <-- here add the query params in your case it will be countryCode
return config;
});
exports.cotacao = async (req, res) => {
try {
req.oexchange = await oexchange.get('latest.json') //here i'm calling external api with query params added in interceptor
return res.status(200).json(req.oexchange.data)
} catch (e) {
res.status(500).json({errors: [{ location: 'cotacao', msg: 'Houve um erro ao acessar a api do open exchange.', param: 'openexchangerates' }]})
}
}
这是在0.19版中添加的已知行为(2019年5月30日)当前,社区正在努力解决该问题,您可以follow here,将在0.20版中进行修复。
如果您希望使用旧的方法来传递url参数,则应向后使用版本0.18。
这里的每个代码都是有效代码,但基于axios documentation
