Я пытаюсь вызвать эту функцию в extractContractsView
.
public getInsurantOrBeneficiary(content_type: number, object_id: number) {
if (content_type == 25) {
this.http.get(AppSettings.API_ENDPOINT + '/api/v1/artifical_persons' + "/" + object_id + "/", this.options)
.map((response: Response) => response.json())
.subscribe((result: any) => {
this.data_name = result;
this.name = this.data_name['name'];
console.log('Artifical persons' + this.name);
return this.name;
});
} else if (content_type == 12) {
this.http.get(AppSettings.API_ENDPOINT + '/api/v1/private_persons' + "/" + object_id + "/", this.options)
.map((response: Response) => response.json())
.subscribe((result: any) => {
this.data_private_persons = result;
this.id_private_persons = this.data_private_persons['passport_id'];
console.log('id_private_persons:' + this.id_private_persons);
});
this.http.get(AppSettings.API_ENDPOINT + '/api/v1/passports' + "/" + this.id_private_persons + "/", this.options)
.map((response: Response) => response.json())
.subscribe((result: any) => {
this.data_name = result;
this.name = this.data_name['second_name'] + ' ' + this.data_name['first_name'] + ' ' + this.data_name['paternal_name'];
console.log('Name in passport:' + this.name);
return this.name;
});
} else if (content_type == 43) {
this.http.get(AppSettings.API_ENDPOINT + '/api/v1/sole_proprietorship' + "/" + object_id + "/", this.options)
.map((response: Response) => response.json())
.subscribe((result: any) => {
this.data_name = result;
this.name = this.data_name['name'];
console.log('sole_proprietorship' + this.name);
return this.name;
});
}
return this.name;
}
Проблема в том, что когда я вызываю функцию getInsurantOrBeneficiary, я получаю данные только на первой итерации. Но content_type [i] и object_id [i] всегда разные, и я ожидаю, что функция вернет другое this.name.
Я не совсем понимаю работу с асинхронностью, и вполне возможно, что this.http.get не успевает работать, и я получаю ответ только один раз.
public extractContractsView = (response: Response) => {
let res = response.json();
let contracts: ContractsView[] = [];
for (let i = 0; i < res.length; i++) {
let insurant = this.getInsurantOrBeneficiary(res[i].insurant_id.content_type, res[i].insurant_id.object_id);
let beneficiary = this.getInsurantOrBeneficiary(res[i].beneficiary_id.content_type, res[i].beneficiary_id.object_id);
contracts.push(new ContractsView(
res[i].id,
res[i].treaty_number,
res[i].days_left,
res[i].days_left_before_the_next_payment,
res[i].payment_status_KB,
res[i].security_deposit_no_deposit,
res[i].currency_conversion_only,
res[i].currency,
res[i].contact,
res[i].additional_information,
res[i].prolongation,
res[i].improving_conditions,
res[i].redundancy,
res[i].akt_on_KB,
res[i].payment_status_akt_on_KB,
insurant,
beneficiary,
res[i].insurance_type_id.name,
res[i].insurer_id.name,
res[i].executor_id,
res[i].status,
res[i].payment,
res[i].time_of_action.date_start + ' - ' + res[i].time_of_action.date_end,
res[i].finance,
res[i].date,
res[i].subagent,
res[i].insurance_object,
));
}
return contracts;
}
public getContracts(): Observable<ContractsView[]> {
let contracts = this.http.get(this.url, this.options)
.map(this.extractContractsView)
.catch(this.handleError);
return contracts;
}
Спасибо за любую помощь.
