在 Ripple 中發送交叉貨幣
我一直在使用 Ripple JSON RPC 面臨這個問題，實際上我正在為跨境交易開發 PoC，作為我的案例的一部分，我需要以 NGN 發送交易並以美元/歐元接收。
我已經閱讀了您的 David Schwartz 回复<https://forum.ripple.com/viewtopic.php?f=2&t=15980>和<https://forum.ripple.com/viewtopic.php?f=2&t=8079>但仍然交易有問題
這是我的要求

但是我沒有指定路徑 bcos 我理解最好在波紋選擇路徑時。
我將不勝感激任何正確方向的幫助

所以，經過很多天，我能夠解決這個問題。我能夠將交易從一位擁有 (NGN) 的客戶發送給另一位以 (USD) 收到交易的客戶。
對於將來可能面臨類似問題的其他人，這是我為解決此問題而採取的步驟。
第1步
我為所有貨幣創建了報價。請參閱下面的範例請求和響應
