### Java POST Request Example

Source: https://www.weex.com/api-doc/ai/QuickStart/RequestInteraction

This Java snippet shows an example of making a POST request to the Weex API. It includes setting up the request body and printing the response. This is a basic example and lacks signature generation and full header construction shown in the Python examples.

```java
System.out.println("GET Response: " + response);
// POST request example
String body = "{\"symbol\": \"ETHUSDT_SPBL\", \"limit\": \"2\"}";
response = sendRequestPost(API_KEY, SECRET_KEY, ACCESS_PASSPHRASE, "POST", requestPath, "", body);
System.out.println("POST Response: " + response);
} catch (Exception e) {
    e.printStackTrace();
}
}
```

### Generate and Send GET Request - Python

Source: https://www.weex.com/api-doc/ai/QuickStart/RequestInteraction

This snippet demonstrates how to generate a signature, construct headers, and send a GET request to the Weex API. It requires API credentials and specifies the request path and query parameters. The response status code and text are printed.

```python
import time
import hmac
import hashlib
import base64
import requests
import json

api_key = ""
secret_key = ""
access_passphrase = ""

def generate_signature_get(secret_key, timestamp, method, request_path, query_string):
  message = timestamp + method.upper() + request_path + query_string
  signature = hmac.new(secret_key.encode(), message.encode(), hashlib.sha256).digest()
  return base64.b64encode(signature).decode()

def send_request_get(api_key, secret_key, access_passphrase, method, request_path, query_string):
  timestamp = str(int(time.time() * 1000))
  signature = generate_signature_get(secret_key, timestamp, method, request_path, query_string)

  headers = {
        "ACCESS-KEY": api_key,
        "ACCESS-SIGN": signature,
        "ACCESS-TIMESTAMP": timestamp,
        "ACCESS-PASSPHRASE": access_passphrase,
        "Content-Type": "application/json",

### Constructing the String to Sign

Source: https://www.weex.com/api-doc/ai/QuickStart/Signature

This snippet illustrates how to construct the message string that will be signed. It concatenates timestamp, method, request path, query string (if present), and request body (if present). The exact format depends on whether a query string exists.

```text
timestamp + method.toUpperCase() + requestPath + "?" + queryString + body
OR
timestamp + method.toUpperCase() + requestPath + body
```
