遇到json时，咱们常常会去作取JSON中某个值的操做，若是是用get方法去取比较繁琐，这里不妨使用jmespath更便捷的方法来解决。css
下面经过代码来讲明jmespath在python中的使用：python
pip install jmespath
import jmespath
source={
"a": "foo",
"b": "bar",
"c": "baz"
}
result = jmespath.search("a",source)
print(result)
输出为：foojson
相似于jsonpath，经过 . 来表示路径的层级数组
source_1={"a":
{"b":
{"c":
{"d":
"value"
}}}}
sub_result = jmespath.search("a.b.c",source_1)
print(sub_result)
输出为：{'d': 'value'}微信
经过索引来访问，主要用于数组less
source_2 = ["a", "b", "c", "d", "e", "f"]
index_result = jmespath.search("[1]",source_2)
print(index_result)
输出为：bide
composite_exp = "a.b.c[0].d[1][0]"
source_3= {"a": {
"b": {
"c": [
{"d": [0, [1, 2]]},
{"d": [3, 4]}
]
}
}}
composite_result = jmespath.search(composite_exp,source_3)
print(composite_result)
输出为：1jsonp
和python切片相似：ui
source_4=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9] slicing_exp = "[0:5]" slicing_result = jmespath.search(slicing_exp,source_4) print(slicing_result)
结果为：[0, 1, 2, 3, 4] slicing的基本格式实际上是： [start:stop:step]spa
投影其实就是初始时定义好格式，而后按照格式的方式进行取值。 投影主要包括如下四种：
字典下的列表 列表下的字典 列表下的列表 字典下的字典 ！！！注意：取列表用的[]，取字典用的.
#1.字典下的列表
source_4={
"people": [
{"first": "James", "last": "d"},
{"first": "Jacob", "last": "e"},
{"first": "Jayden", "last": "f"},
{"missing": "different"}
],
"foo": {"bar": "baz"}
}
query = jmespath.search("people[:2].first", source_4)
print(query)
# 结果是：['James', 'Jacob']
# 2. 列表下的字典
query = ```
hotCommentTagStatistics[].{
content:name,
comment_count:count
}```
#3. 列表下的列表
[][0]
#4 字典下的字典
query = ```
productCommentSummary.{
goods_id:productId
good_rate:goodRate
}```
实际例子：(拿京东爬虫数据解析为例)
import jmespath
query = '''
productCommentSummary.{
goods_id:productId
good_rate:goodRate
}'''
