作為我們Block Producer來說對社群利益承諾的一部分,是我們希望專注於構建一些有助於提高EOS平臺採用率的工具或者應用程式。與許多大多數大型應用程式一樣,當你只有少量或過時的文件並且缺乏工具來幫助你進行入門學習時,可能就會存在很高的進入門檻。
為了節省剛入門的EOS開發人員一些時間,我們整理了一個PHP SDK,它涵蓋了大部分EOS的API方法。在文件中,每個呼叫都有一些示例,其中包含API的實際輸出。
無論你是否使用PHP,我們都希望這將是一個有用的參考點,可以開始構建你的第一個應用程式,或者只是瞭解EOS區塊鏈API提供的內容也好。
你可以檢視EOS官方文件,但要注意缺少一些較新的方法。此外,這些文件中的一些示例使用了過時的語法。
安裝
composer require block-matrix-network/php-eos-rpc-sdk
設定
使用你喜歡的RPC API主機在專案根目錄中建立一個dotenv .env
檔案。你可以使用.env.example
作為模板:
cp .env.example .env
用法
有一個工廠方法來自動例項化所有依賴項:
$api = (new ChainFactory)->api();
示例
為了幫助你入門,有一個簡單的示例執行器,它涵蓋了所有API命令。
只需透過cli執行此命令即可檢視所有命令的示例輸出:
cd examples
php chain.php
API方法
涵蓋了所有隻讀的EOS區塊鏈API方法。下面舉幾個例子:
