JsonPath JUnit escape character for dots
提问by cloudy_weather
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 :
我有一个名为 template.welcome.email 的 json 字段，我正在编写一个单元测试，检查服务器的回复中是否存在该字段，但我找不到字段名称中点的转义符. 我的测试代码是：
@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));
}
But I get the following exception, because the dots are interpreted like paths:
但是我得到以下异常，因为这些点被解释为路径：
java.lang.AssertionError: No value for JSON path: $.template.welcome.email, exception: invalid path

Do you know any escape character for the jsonPath?
你知道 jsonPath 的任何转义字符吗？

As Idapointed out:
Use brackets and quotes around your field. For example, if your field is valid.key.with.dot
Refer to it as ['valid.key.with.dot'] and in JsonPath, try
JsonPath.read(jsonString, "$.['valid.key.with.dot']")
在您的字段周围使用括号和引号。例如，如果您的字段是 valid.key.with.dot
将其称为 ['valid.key.with.dot'] 并在 JsonPath 中尝试
JsonPath.read(jsonString, "$.['valid.key.with.dot']")

These days (e.g. io.rest-assured.json-path:3.0.1) the notation seems to be without brackets:
这些天（例如io.rest-assured.json-path:3.0.1）符号似乎没有括号：
// Some Groovy OData V4 $count test
// Response looks like:
// { "@odata.count": 2, ... }
body "'@odata.count'", equalTo(2)
I found the corresponding hint in this Git issue.
我在这个 Git 问题中找到了相应的提示。
