Rest Assured使用Groovy的GPath表示法，不要与Jayway的JsonPath语法混淆
我是RestAssured的新手，正在尝试以下代码：
@Test
public void testJsonPath() {
Response response = RestAssured
.given()
.param("id", "2172797")
.param("appid", "439d4b804bc8187953eb36d2a8c26a02")
.when()
.get("https://samples.openweathermap.org/data/2.5/weather");
String value = "weather[*].description";
System.out.println(value);
String data = response.then().contentType(ContentType.JSON).extract().path(value);
System.out.println(data);
}
JSON:
{
"coord": {
"lon": 145.77,
"lat": -16.92
},
"weather": [
{
"id": 802,
"main": "Clouds",
"description": "scattered clouds",
"icon": "03n"
}
],
"base": "stations",
"main": {
"temp": 300.15,
"pressure": 1007,
"humidity": 74,
"temp_min": 300.15,
"temp_max": 300.15
},
"visibility": 10000,
"wind": {
"speed": 3.6,
"deg": 160
},
"clouds": {
"all": 40
},
"dt": 1485790200,
"sys": {
"type": 1,
"id": 8166,
"message": 0.2064,
"country": "AU",
"sunrise": 1485720272,
"sunset": 1485766550
},
"id": 2172797,
"name": "Cairns",
"cod": 200
}
Getting the following error:
java.lang.IllegalArgumentException: Invalid JSON expression:
Script1.groovy: 1: unexpected token: ] @ line 1, column 36.
weather[*].description
为什么在使用*时会出现以下错误？。替换时字符串值="weather[0].description"；它运行良好。有人能帮我做这个吗。
我也检查了邮递员，API给出了正确的输出。
Note: When using creating code (weather[*].description) from http://jsonpath.com/. It gives the same output.
If there is anything I am missing anything please let me know as I am new to it. Any help to this would be great.
It can also be great if someone can give me a brief on this and let me know whom to refer to get the best output from this.

官方文件
GPath
JsonPath
编辑：
｛"users"：[｛"firstName"："sijo"，"lastName"："john"，"subjectId"：1，"id"：1｝，｛"第一名称"："sonia"，"最后名称"："sahay"，"主题id"：2｝，"第一名称"："shreya"，"最后名称"：name"："SDET"}]}
对于上面的JSON，您可以使用下面的来获取所有lastName
JsonPath abc = new JsonPath(res);
String deal = abc.getString("users.lastName");
System.out.println(deal);
