+
+#### **XHR**
+
+```javascript
+// 创建一个 XMLHttpRequest 对象
+const xhr = new XMLHttpRequest();
+
+// 使用
+// GET
+xhr.open('GET', 'https://api.example.com/data', true);
+xhr.onreadystatechange = function() {
+    if (xhr.readyState === 4 && xhr.status === 200) {
+        console.log(xhr.responseText); // 处理响应
+    }
+};
+xhr.send(null);
+
+// POST
+xhr.open('POST', 'https://api.example.com/submit', true);
+xhr.setRequestHeader('Content-Type', 'application/json;charset=UTF-8');
+xhr.onreadystatechange = function() {
+    if (xhr.readyState === 4 && xhr.status === 200) {
+        console.log(xhr.responseText);
+    }
+};
+// 假设我们发送的是 JSON 格式的数据
+const data = JSON.stringify({key1: 'value1', key2: 'value2'});
+xhr.send(data);
+```
+
+#### **AXIOS**
+
+```javascript
+// 导入
+<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
+
+// 使用
+// GET
+axios.get('https://api.example.com/data')
+  .then(function (response) {
+    // 成功处理
+    console.log(response.data);
+  })
+  .catch(function (error) {
+    // 错误处理
+    console.error(error);
+  });
+
+// POST
+// 发送 JSON 数据
+axios.post('https://api.example.com/submit', {
+    key1: 'value1',
+    key2: 'value2'
+  })
+  .then(function (response) {
+    console.log(response.data);
+  })
+  .catch(function (error) {
+    console.error(error);
+  });
