The quickest way to start building on Bitcoin Cash with Quicknode is by sending a JSON-RPC request to your endpoint. In this quickstart, you'll create an endpoint, copy its provider URL, and make your first request. Code samples are available in cURL as well as popular SDKs and programming languages.
Get Your Bitcoin Cash Endpoint
如需了解Quicknode 詳細操作指南，請參閱我們的 指南
發送您的第一項請求
Your endpoint is ready. Now, let's make your first call to the Bitcoin Cash blockchain. We'll use the getblock method, which retrieves detailed information about a specific block by its hash. 請選擇您偏好的語言或SDK 依照以下步驟發送您的第一個請求.
- cURL
Python- JavaScript
- Ruby
檢查 cURL 的安裝狀況
大多數基於 *nix 的系統預設即支援 cURL。請開啟終端機，並執行以下指令以檢查 cURL 的版本：
curl --version
傳送一個 JSON-RPC 請求
In your terminal, copy and paste the following cURL command to retrieve block information:
curl YOUR_QUICKNODE_ENDPOINT_URL/ \
-X POST \
-H "Content-Type: application/json" \
--data '{"id": 1, "jsonrpc": "2.0", "method": "getblock", "params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]}'

設定您的專案
為您的 Python 專案建立一個新目錄：
mkdir bitcoincash-python-quickstart
cd bitcoincash-python-quickstart
建立並啟用虛擬環境
建立一個虛擬環境來管理依賴項：
python3 -m venv venv
source venv/bin/activate
安裝請求
安裝 requests 函式庫，以便發送 HTTP 請求：
pip 安裝 requests
建立一個 Python 腳本（app.py）
建立一個包含以下程式碼的 Python 檔案：
import requests
import json
# Your Quicknode endpoint URL
url = "YOUR_QUICKNODE_ENDPOINT_URL/"
# JSON-RPC request payload for getblock
payload = json.dumps({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
})
headers = {
'Content-Type': 'application/json'
}
# Make the request
response = requests.request("POST", url, headers=headers, data=payload)
result = response.json()
print("Block information:")
print(json.dumps(result, indent=2))
執行該腳本
執行您的 Python 腳本：
python app.py
設定您的專案
建立一個新目錄並初始化一個 Node.js 專案：
mkdir bitcoincash-js-quickstart
cd bitcoincash-js-quickstart
npm init -y
建立一個 JavaScript 檔案（app.js）
Create an app.js file with the following code (using native https module):
const https = require('https');
// Your Quicknode endpoint URL
const data = JSON.stringify({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
});
const options = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': data.length
}
};
const req = https.request(options, (res) => {
let result = '';
res.on('data', (chunk) => {
result += chunk;
});
res.on('end', () => {
console.log('Block information:');
console.log(JSON.parse(result));
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.write(data);
req.end();

請確認您的系統上已安裝 Ruby。若尚未安裝，請從 https://ruby-lang.org 進行安裝：
ruby --version
建立一個 Ruby 腳本（main.rb）
建立一個名為 main.rb 的檔案，並輸入以下程式碼：
require "uri"
require "json"
require "net/http"
# Your Quicknode endpoint URL
url = URI("YOUR_QUICKNODE_ENDPOINT_URL/")
https = Net::HTTP.new(url.host, url.port)
https.use_ssl = true
request = Net::HTTP::Post.new(url)
request["Content-Type"] = "application/json"
request.body = JSON.dump({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
})
response = https.request(request)
result = JSON.parse(response.read_body)
puts "Block information:"
puts JSON.pretty_generate(result)
