删除 JSON 数组中出现的特定 JSONobject 的 WSO2 Mediator [英] WSO2 Mediator that removes specific JSONobject occurrences within a JSON array
问题描述
这是我第一次在 wso2 中使用 json 数组转换响应.我正在创建一个 wso2 流出调解器,用于删除 json 数组响应中的特定 json 对象
this is my first time transforming a response with json arrays in wso2. I am creating a wso2 outflow mediator that removes a specific json object within a json array response
使用payloadfactory序列中介,我试图从json数组中删除json对象price".我遵循了 wso2 文档,但它的以太我得到了一个空的主体响应,或者 wso2 拒绝了流出序列.
Using payloadfactory sequence mediator, I was trying to remove the json object "price" from the json arrays. I followed the wso2 documentation but its ether i get an empty body response or the wso2 rejects the outflow sequence.
示例响应:
{
"results": [
{
"name": "user",
"item": "test",
"price": {
"pricePerItem": 2.0,
"currency": "USD"
},
"stat": {
"groupId": 3,
"groupName": "DELIVERED",
}
},
{
"name": "user2",
"item": "test2",
"price": {
"pricePerItem": 4.0,
"currency": "USD"
},
"stat": {
"groupId": 4,
"groupName": "DELIVERED",
}
}
]
}
我的流出代码:
<?xml version="1.0" encoding="UTF-8"?>
<sequence name="test_outflow.xml" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<payloadFactory media-type="json">
<format>
$1
</format>
<args>
<arg evaluator="json" expression="$.results"/>
</args>
</payloadFactory>
<script language="js"><![CDATA[
var payload = mc.getPayloadJSON();
results = payload.results;
response = new Array();
for (i = 0; i < results.length; ++i) {
delete payload[i].id;
response[i] = l;
}
mc.setPayloadJSON(response);
]]></script>
<property name="messageType" scope="axis2" type="STRING" value="application/json"/>
</sequence>
预期结果:
{
"results": [
{
"name": "user",
"item": "test",
"stat": {
"groupId": 3,
"groupName": "DELIVERED",
}
},
{
"name": "user2",
"item": "test2",
"stat": {
"groupId": 4,
"groupName": "DELIVERED",
}
}
]
}
你们有没有遇到过这种情况?谢谢!
If any of you have experience with this kind of situation? thanks!
推荐答案
您可以使用以下内联脚本来实现您的需求
You can use the following inline script to achieve your requirement
<script language="js" xmlns="http://ws.apache.org/ns/synapse"><![CDATA[
var payload = mc.getPayloadJSON();
var results = payload.results;
var response = new Array();
for (var i = 0; i < results.length; ++i) {
delete results[i].price;
response[i] = results[i];
}
payload.results = response;
mc.setPayloadJSON(payload);
]]></script>

下面给出的是为以下模拟需求开发的示例外序列(突触)
Given below is a sample out-sequence (synapse) developed for the following mock requirement
实际响应(修改前):
{
"results": [
{
"name": "Athiththan",
"price": {
"value": 120
}
},
{
"name": "athiththan11",
"price": {
"value": 100
}
}
]
}
异常响应(修改后):
{
"results": [
{
"name": "Athiththan"
},
{
"name": "athiththan11"
}
]
}
外序列突触配置:
<?xml version="1.0" encoding="UTF-8"?>
<outSequence xmlns="http://ws.apache.org/ns/synapse">
<script language="js"><![CDATA[
var payload = mc.getPayloadJSON();
var results = payload.results;
var response = new Array();
for (var i = 0; i < results.length; ++i) {
delete results[i].price;
response[i] = results[i];
}
payload.results = response;
mc.setPayloadJSON(payload);
]]></script>
<send/>
</outSequence>
