在使用axios和React Native与IdentityServer4进行令牌请求时,通常会涉及到OAuth 2.0授权流程。以下是一个基本的示例,展示了如何使用axios从React Native应用中请求访问令牌。
首先,确保你已经安装了axios和react-native-secure-storage(或其他安全的存储解决方案)。
npm install axios react-native-secure-storage
创建一个axios实例,并设置基础URL和其他默认配置。
import axios from 'axios';
const apiClient = axios.create({
baseURL: 'https://your-identityserver-url',
timeout: 1000,
});
使用axios发送POST请求以获取访问令牌。通常,这涉及到发送客户端凭据(client_id和client_secret)以及授权类型(grant_type)。
import { SecureStore } from 'react-native-secure-storage';
const getToken = async () => {
try {
const response = await apiClient.post('/connect/token', {
grant_type: 'client_credentials',
client_id: 'your-client-id',
client_secret: 'your-client-secret',
scope: 'your-scope',
});
const { access_token, expires_in, token_type } = response.data;
// 存储令牌到安全存储
await SecureStore.setItemAsync('access_token', access_token);
await SecureStore.setItemAsync('expires_in', expires_in);
await SecureStore.setItemAsync('token_type', token_type);
return access_token;
} catch (error) {
console.error('Error fetching token:', error);
throw error;
}
};
在需要访问受保护资源的地方,从安全存储中获取令牌并附加到请求头中。
import { SecureStore } from 'react-native-secure-storage';
const fetchProtectedData = async () => {
try {
const accessToken = await SecureStore.getItemAsync('access_token');
const tokenType = await SecureStore.getItemAsync('token_type');
const response = await apiClient.get('/protected-resource', {
headers: {
Authorization: `${tokenType} ${accessToken}`,
},
});
return response.data;
} catch (error) {
console.error('Error fetching protected data:', error);
throw error;
}
};
import axios from 'axios';
import { SecureStore } from 'react-native-secure-storage';
const apiClient = axios.create({
baseURL: 'https://your-identityserver-url',
timeout: 1000,
});
const getToken = async () => {
try {
const response = await apiClient.post('/connect/token', {
grant_type: 'client_credentials',
client_id: 'your-client-id',
client_secret: 'your-client-secret',
scope: 'your-scope',
});
const { access_token, expires_in, token_type } = response.data;
await SecureStore.setItemAsync('access_token', access_token);
await SecureStore.setItemAsync('expires_in', expires_in);
await SecureStore.setItemAsync('token_type', token_type);
return access_token;
} catch (error) {
console.error('Error fetching token:', error);
throw error;
}
};
const fetchProtectedData = async () => {
try {
const accessToken = await SecureStore.getItemAsync('access_token');
const tokenType = await SecureStore.getItemAsync('token_type');
const response = await apiClient.get('/protected-resource', {
headers: {
Authorization: `${tokenType} ${accessToken}`,
},
});
return response.data;
} catch (error) {
console.error('Error fetching protected data:', error);
throw error;
}
};
通过这种方式,你可以使用axios和React Native与IdentityServer4进行安全的令牌请求和资源访问。
