WSO2 构建直通流时出错 java.lang.StringIndexOutOfBoundsException

问题描述 投票：0回答：1

我有 API Manager 公开的 Micro Integrator API。当客户端测试它时，他们会收到以下错误，并且请求甚至没有记录（日志是此 API 中的第一个中介）。当我尝试与邮递员相同的请求时，一切正常。我无法重新创建此错误，客户端声称他们正在正确发送请求，您知道这个 java.lang.StringIndexOutOfBoundsException 错误可能意味着什么吗？

消息生成器在到达您的集成之前就失败了。我假设您正在发送内容类型为“application/x-www-form-urlencoded”的消息，该错误是从代码中的 this 行引发的。出现此错误的唯一可能是您发送的参数没有分隔符
