春天開機TestRestTemplate不URL解碼requestparam值

Question

設置：

• 春天引導+ SpringBootApplication;用於測試的Spring Boot Test + TestRestTemplate
• 1個端點，由foo方法處理。
• 輸入：1個必需請求參數（名爲q），必須在URI中進行URL編碼。
• 輸出：（foo）只返回字符串（q）。沒有由foo完成的處理。

如果我啓動服務器並使用URL編碼值捲曲端點，則會在響應中獲得非URL編碼值。

如果我查詢同樣的事情與TestRestTemplate，FOO得到一個URL編碼值來處理，事情開始在現實世界中去錯了...

Answer 1

您正在碰到this bug。您可以通過使用String而不是URI來調用TestRestTemplate來避免此問題。
