我正在尝试将字符串数组转换为常规字符串。但是使用我的spec文件,它会以数组的形式返回
样本输入(来自ES)
{
...
"hits": {
"total": 1,
"max_score": 1.4818809,
"hits": [
{
"_index": "twitter",
"_type": "tweet",
"_id": "1",
"_score": 1.4818809,
"_source": {
"user": "test",
"message": "some message with the number 1",
"date": "2009-11-15T14:12:12",
"likes": 1
},
"highlight": {
"message": [
"some message with the <em>number</em> <em>1</em>"
]
}
}
]
}
}
规范文件
[
{
"operation": "shift",
"spec": {
"took": "took",
"hits": {
"total": "total_hits",
"hits": {
"*": {
"_source": {
"user": "Response[&2].firstName"
},
"highlight": {
"message": ["Response[&2].h_message"]
}
}
}
}
}
}
]
输出:
{
"Response" : [ {
"firstName" : "test",
"h_message" : [ "some message with the <em>number</em> <em>1</em>" ]
} ],
"total_hits" : 1
}
正如您所看到的,“h_message”将作为一个数组出现。我想获得的是一个字符串/值
"h_message" : [ "some message with the <em>number</em> <em>1</em>" ]
答案 0 :(得分:0)
解决了它
[
{
"operation": "shift",
"spec": {
"took": "took",
"hits": {
"total": "total_hits",
"hits": {
"*": {
"_source": {
"user": "Response[&2].firstName"
},
"highlight": {
"message": {
"*": "Response[&0].h_message"
}
}
}
}
}
}
}
