点的 JsonPath JUnit 转义字符 [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来检查该字段是否存在于服务器的回复中,但我找不到名称中点的转义符领域的.我的测试代码是:
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));
}
但我得到以下异常,因为点被解释为路径:
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

你知道 jsonPath 的任何转义字符吗?
Do you know any escape character for the jsonPath?
推荐答案
在您的字段周围使用括号和引号.例如,如果您的字段是 valid.key.with.dot
Use brackets and quotes around your field. For example, if your field is valid.key.with.dot
将其称为 ['valid.key.with.dot'] 并在 JsonPath 中尝试
Refer to it as ['valid.key.with.dot'] and in JsonPath, try
JsonPath.read(jsonString, "$.['valid.key.with.dot']")
