JsonPath JUnit转义字符点 [英] JsonPath JUnit escape character for dots

问题描述

我有一个名为template.welcome.email的json字段，我正在编写一个单元测试，以检查服务器的回复中是否存在该字段，但是我找不到名称中的点的转义符领域的. 我测试的代码是:

I have a json field which is called template.welcome.email and I am writing a unit test that checks if that field is present in the reply from the server but I can't find an escape for the dots in the name of the field. The code of my test is :

@Test
public void testEmailTemplates() throws Exception {     
    mockMvc.perform(get("/emailTemplates")
        .contentType(MediaType.APPLICATION_JSON)
        .locale(Locale.UK)
        .accept(MediaType.APPLICATION_JSON))

        .andDo(print())
        .andExpect(status().isOk())

        .andExpect(jsonPath("$.template.welcome.email").exists())

        .andExpect(redirectedUrl(null))
        .andExpect(forwardedUrl(null));
}

但是我得到了以下异常，因为点的解释就像路径一样:

But I get the following exception, because the dots are interpreted like paths:

java.lang.AssertionError: No value for JSON path: $.template.welcome.email, exception: invalid path

您知道jsonPath的任何转义字符吗?

Do you know any escape character for the jsonPath?

推荐答案

为 Ida

在您的字段中使用方括号和引号.例如，如果您的字段是有效的.key.with.dot

Use brackets and quotes around your field. For example, if your field is valid.key.with.dot

将其引用为['valid.key.with.dot']，然后在JsonPath中尝试

Refer to it as ['valid.key.with.dot'] and in JsonPath, try

JsonPath.read(jsonString, "$.['valid.key.with.dot']")
