问题描述 #

访问/test端点时出现500错误，原因是Handlebars模板引擎尝试解析jsonStringKey1的值时导致JSON解析失败，具体错误日志如下：

HTTP ERROR 500 com.github.tomakehurst.wiremock.common.JsonException: { "errors" : [ { "code" : 10, "source" : { }, "title" : "Error parsing JSON", "detail" : "Unexpected character ('k' (code 107)): was expecting comma to separate Object entries\n at [Source: (String)\"{\"data\":[{\"key1\":\"value\",\"nestedKey1\":{\"key2\":\"value2\"},\"jsonStringKey1\":\"{\"key\": \"value\", \"nestedKey\": {\"key2\": \"value2\"},}\"}]}\"; line: 1, column: 78]" } ] }

已尝试的无效方案 #

• 使用{{{ }}}包裹值，无效
• 尝试多种转义方式，无效
• 使用{{!-- --}}包裹跳过处理，但jsonStringKey1返回空字符串

求助 #

有没有人遇到过类似问题，能提供解决方案？
