[TOC] ###途牛簽名流程 1. 將入參按照一級key值進行排序，去掉value值為空的入參，我們將得到以下格式參數+系統參數）如下 ` { "agencyProductId":"test10001", "apiKey":"testApiKey", "planInfo":[{ "planDateStr":"2015-07-18", "datePriceList":[{ "schemeId":"scheme0001", "scheduleId":"schedule", "agencyBudget":1000, "agencyBudgetChild":500, "excludeChild":1, "roomAddBudget":100, "roomGapFlag":1, "aheaddate":4, "deadlinedate":3, "deadlinehour":18, "promoFlag":1, "setGroupFlag":1, "stuffEndDate":5 }] }], "timestamp":"2015-07-30 12:34:56" } ` 2. 將排序好的入參依次拼接起來，如下： ` agencyProductIdtest10001apiKeytestApiKeyplanInfo[{"planDateStr":"2015-07-18","datePriceList":[{"schemeId":"scheme0001","scheduleId":"schedule","agencyBudget":1000,"agencyBudgetChild":500,"excludeChild":1,"roomAddBudget":100,"roomGapFlag":1,"aheaddate":4,"deadlinedate":3,"deadlinehour":18,"promoFlag":1,"setGroupFlag":1,"stuffEndDate":5}]}]timestamp2015-07-30 12:34:56` 3. 在拼好的字符串前后都加上簽名密鑰，我們假設密鑰是ZbWjUMYevqT9Tnup4jRs,可以得到以下字符串： `ZbWjUMYevqT9Tnup4jRsagencyProductIdtest10001apiKeytestApiKeyplanInfo[{"planDateStr":"2015-07-18","datePriceList":[{"schemeId":"scheme0001","scheduleId":"schedule","agencyBudget":1000,"agencyBudgetChild":500,"excludeChild":1,"roomAddBudget":100,"roomGapFlag":1,"aheaddate":4,"deadlinedate":3,"deadlinehour":18,"promoFlag":1,"setGroupFlag":1,"stuffEndDate":5}]}]timestamp2015-07-30 12:34:56ZbWjUMYevqT9Tnup4jRs` 4. 對生成的字符串進行MD5加密，并將結果全部轉為大寫，獲得簽名值: `E30F44C19525EFD997BB8791421C3206` 5. 將簽名加入到入參中： ` { "agencyProductId":"test10001", "apiKey":"testApiKey", "planInfo":[{ "planDateStr":"2015-07-18", "datePriceList":[{ "schemeId":"scheme0001", "scheduleId":"schedule", "agencyBudget":1000, "agencyBudgetChild":500, "excludeChild":1, "roomAddBudget":100, "roomGapFlag":1, "aheaddate":4, "deadlinedate":3, "deadlinehour":18, "promoFlag":1, "setGroupFlag":1, "stuffEndDate":5 }] }], "timestamp":"2015-07-30 12:34:56", "sign":"E30F44C19525EFD997BB8791421C3206" } ` 6.發起HTTP請求。
