我在Flutter中有一个POST请求，效果很好，但CORS阻止了它。 （我已经在chrome上禁用了安全性并对其进行了正确的测试）。因此，我决定将其设置为Firebase Functions中的可调用函数，似乎可以与服务器联系，但不推送数据吗？
我使用了express，但没有给我任何回应，所以我决定使用axios，这是一个基于Promise的HTTP客户端。它记录响应，但随后超时。
很高兴有任何输入可以发布此数据。
Flutter POST（除CORS阻止以外的其他方法）
if (softwareProvider == 'provider') {
String url = 'https://website.com/EnquiryServlet?license=12345';
Response response = await post(url, body: {
'firstName': firstName,
'lastName': lastName,
'email': email,
});
print(response.body);
index.js中的云功能
const axios = require('axios');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.providerPOST = functions.https.onRequest((req,res) => {
axios.post('https://website.com/EnquiryServlet?license=12345', {
firstName: 'John',
lastName: 'Smith',
email: 'john.smith@gmail.com'
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
})
