[英]Google Data Studio - Custom Connector - Get Data parsing json
我正在嘗試在 GDS 上為外部 API 構建自定義連接器。
我已經使用來自 API 的所有字段配置了架構,當我部署並嘗試連接器時,我可以正確地看到它。 但是,當我嘗試運行“Explore”時,我得到一個通用的“數據集配置錯誤 - Data Studio 無法連接到您的數據集”。 我正在按要求傳遞一組鍵值對……所以不確定發生了什么。
這是我在 getData function 中使用的代碼
function getData(request) {
try {
request.configParams = validateConfig(request.configParams);
var requestedFields = getFields().forIds(
request.fields.map(function(field) {
return field.name;
})
);
var data = JSON.parse(jsonSample).Table
return {
schema: requestedFields.build(),
rows: data
};
}
catch (e) {
cc.newUserError()
.setDebugText('Error fetching data from API. Exception details: ' + e)
.setText(
'The connector has encountered an unrecoverable error. Please try again later, or file an issue if this error persists.'
)
.throwException();
}
}
其中 jsonSample 是一個文本字符串,包含以下 json(原始,未美化):
{
"Table": [
{
"Entity": "Houston Heights",
"EntityD": "",
"Consolidation": "USD",
"ConsolidationD": "United States of America, Dollars",
"Scenario": "Actual",
"ScenarioD": "",
"Time": "2010M1",
"TimeD": "Jan 2010",
"View": "Periodic",
"ViewD": "",
"Account": "IFRS Balance Sheet",
"AccountD": "",
"Flow": "None",
"FlowD": "",
"Origin": "BeforeAdj",
"OriginD": "",
"IC": "None",
"ICD": "",
"UD1": "None",
"UD1D": "",
"UD2": "None",
"UD2D": "",
"UD3": "None",
"UD3D": "",
"UD4": "None",
"UD4D": "",
"UD5": "None",
"UD5D": "",
"UD6": "None",
"UD6D": "",
"UD7": "None",
"UD7D": "",
"UD8": "None",
"UD8D": "",
"CellValue": 2.25000000000000000000
},
{
"Entity": "Houston Heights",
"EntityD": "",
"Consolidation": "USD",
"ConsolidationD": "United States of America, Dollars",
"Scenario": "Actual",
"ScenarioD": "",
"Time": "2010M1",
"TimeD": "Jan 2010",
"View": "Periodic",
"ViewD": "",
"Account": "IFRS Balance Sheet",
"AccountD": "",
"Flow": "None",
"FlowD": "",
"Origin": "BeforeAdj",
"OriginD": "",
"IC": "None",
"ICD": "",
"UD1": "Admin",
"UD1D": "Admin",
"UD2": "None",
"UD2D": "",
"UD3": "None",
"UD3D": "",
"UD4": "None",
"UD4D": "",
"UD5": "None",
"UD5D": "",
"UD6": "None",
"UD6D": "",
"UD7": "None",
"UD7D": "",
"UD8": "None",
"UD8D": "",
"CellValue": 2.240000000000000000000
}
]
}
要解決這個問題,代碼應該是這樣的,因為你正在傳遞一個對象數組:
function getData(request) {
try {
request.configParams = validateConfig(request.configParams);
var requestedFields = getFields().forIds(
request.fields.map(function (field) {
return field.name;
})
);
var data = JSON.parse(jsonSample).Table;
return {
schema: requestedFields.build(),
rows: data.map(function (row) {
var values = [];
requestedFields.asArray().forEach(function (field) {
values.push(row[field.getId()]);
});
return { values: values };
}),
};
} catch (e) {
cc.newUserError()
.setDebugText("Error fetching data from API. Exception details: " + e)
.setText(
"The connector has encountered an unrecoverable error. Please try again later, or file an issue if this error persists."
)
.throwException();
}
}
