我正在为Data Studio开发连接器，并且具有以下架构：
var azulDataSchema = [
{
name: 'NUMBER',
label: 'SALE NUMBER',
dataType: 'STRING',
semantics: {
conceptType: 'DIMENSION'
}
},
{
name: 'STATUS',
label: 'SALE STATUS',
dataType: 'STRING',
semantics: {
conceptType: 'DIMENSION'
}
},
{
name: 'CUSTOMER_NAME',
label: 'CUSTOMER NAME',
dataType: 'STRING',
semantics: {
conceptType: 'DIMENSION'
}
},
{
name: 'PAYMENT_INSTALLMENTS_NUMBER',
label: 'PAYMENT_INSTALLMENTS_NUMBER',
dataType: 'STRING',
semantics: {
conceptType: 'DIMENSION',
}
},
{
name: 'PAYMENT_INSTALLMENTS_VALUE',
label: 'PAYMENT_INSTALLMENTS_VALUE',
dataType: 'NUMBER',
semantics: {
conceptType: 'METRIC',
isReaggregatable: true
}
},
{
name: 'PAYMENT_INSTALLMENTS_STATUS',
label: 'PAYMENT_INSTALLMENTS_STATUS',
dataType: 'STRING',
semantics: {
conceptType: 'DIMENSION'
}
}
]
因此，对于一次销售（由NUMBER标识），我可以有一个或更多 付款方式。
**The response of API is:**
[
{
"id":"58fe71af-a9d5-410d-b729-db9b2c7494d3",
"number":3,
"status":"COMMITTED",
"customer":{
"name":"CLIENTE JOSÉ"
},
"payment":{
"installments":[
{
"number":1,
"value":8,
"status":"PENDING"
},
{
"number":2,
"value":8,
"status":"PENDING"
},
{
"number":3,
"value":8,
"status":"PENDING"
},
{
"number":4,
"value":8,
"status":"PENDING"
},
{
"number":5,
"value":8,
"status":"PENDING"
}
]
},
"total":80
}
]
我为Data Studio传递数据的功能是：
function getData(request) {
var dataSchema = [];
request.fields.forEach(function(field) {
for (var i = 0; i < azulDataSchema.length; i++) {
if (azulDataSchema[i].name === field.name) {
dataSchema.push(azulDataSchema[i]);
break;
}
}
});
var response = scriptProperties.getProperty("Data");
response = JSON.parse(response);
var data = [];
try{
//begin object keys foreach
Object.keys(response).forEach(function(sale) {
var values = [];
//begin dataSchema foreach
dataSchema.forEach(function(field) {
switch(field.name){
case 'NUMBER':
if(response[sale].number != undefined && response[sale].number != null){
values.push(response[sale].number.toString());
}
break;
case 'STATUS':
if(response[sale].status != undefined &&
response[sale].status != null){
values.push(response[sale].status);
}
break;
case 'CUSTOMER_NAME':
if(response[sale].customer != undefined &&
response[sale].customer != null){
values.push(response[sale].customer.name);
}
break;
//BEGIN INSTALLMENTS
//*******FROM HERE, SOMETHING IS NOT CORRECT*****
case 'PAYMENT_INSTALLMENTS_NUMBER' :
if(response[sale].payment.installments != null){
response[sale].payment.installments.forEach(function (installmentNumber){
values.push(installmentNumber.number.toString());
});
}
break;
case 'PAYMENT_INSTALLMENTS_VALUE':
if(response[sale].payment.installments != null){
response[sale].payment.installments.forEach(function (installmentValue){
values.push(installmentValue.value);
});
}
break;
case 'PAYMENT_INSTALLMENTS_STATUS':
if(response[sale].payment.installments != null){
response[sale].payment.installments.forEach(function (installmentStatus){
values.push(installmentStatus.status);
});
}
break;
//END INSTALLMENTS
case 'TOTAL':
if(response[sale].total != undefined){
values.push(response[sale].total);
}else{
values.push(0);
}
break;
default:
values.push("");
}//END swith case
}); //END dataSchema foreach
data.push({
values: values,
});
});//END object keys foreach
}catch(error){
Logger.log('ERRO: ' + error);
}
return {
schema: dataSchema,
rows: data
};
};//END function
将数据传递到Data Studio的方式是：
[
{
"values":[
"JOSÉ", //customer name
"3", //number of sale
"1", //installment number (of this sale)
"2", //installment number (of this sale)
"3", //installment number (of this sale)
"4", //installment number (of this sale)
"5", //installment number (of this sale)
"PENDING", //installment status (of this sale)
"PENDING", //installment status (of this sale)
"PENDING", //installment status (of this sale)
"PENDING", //installment status (of this sale)
"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
8, //installment value (of this sale)
8, //installment value (of this sale)
8, //installment value (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
}
]
因此，对于forEach，我试图传递一次销售的INSTALLMENTS列表，但是当我尝试在Data Studio中查看它时，我得到了错误代码 （0e99578d）：[错误数据工作室] [1]

应该具有从getData到值的一对一映射，并且值必须是标量（即field.name，string或number）。如果boolean请求中有3个fields，则您的响应应包含三个条目。 （即类似getData的东西）当前，您的{"values":[1, 2, 3]}响应在模式期望为6时返回19个条目。
对于您的特定用例，有两种解决方法。
按照这种方法，您的getData响应类似于以下内容：
getData如果对您的数据有意义，则可以通过求和，求平均或通过其他任何聚合来汇总这些字段，这些汇总采用每个架构字段的多个值并将其转换为标量值。
按照这种方法，您的[
{
"values": [
"JOSÉ", //customer name
"3", //number of sale
"1", //installment number (of this sale)
"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
},
{
"values": [
"JOSÉ", //customer name
"3", //number of sale
"2", //installment number (of this sale)
"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
},
{
"values": [
"JOSÉ", //customer name
"3", //number of sale
"3", //installment number (of this sale)
"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
},
{
"values": [
"JOSÉ", //customer name
"3", //number of sale
"4", //installment number (of this sale)
"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
},

"JOSÉ", //customer name

"PENDING", //installment status (of this sale)
8, //installment value (of this sale)
"COMMITTED", //sale status
80 //total sale
]
}
]
响应看起来像这样：
getData请注意，我删除了分期付款编号条目，因为如果将这些值进行汇总，则可能没有意义。
有关其他任何详细信息，请参见Data Studio社区连接器参考中的getData。
