验证地址

如需在 Maps JavaScript API 中使用 Address Validation 验证地址，请调用 fetchAddressValidation 方法，传递包含要验证的地址的请求正文，如以下示例所示。 

async function validateAddress() {
  // Import the Address Validation library.
  const {AddressValidation} =
      await google.maps.importLibrary('addressValidation');
  // Call the fetchAddressValidation method.
  const result = await AddressValidation.fetchAddressValidation({
    address: {
      postalCode: '94043',
      regionCode: 'US',
      languageCode: 'en',
      addressLines: ['1600 Amphitheatre', 'Parkway'],
    }
  });
  // Log the results to the console.
  document.querySelector('pre').textContent =
      JSON.stringify(result, null, '  ');
}

您可以使用各个组成部分来定义地址，也可以使用 addressLines 将整个设有格式的地址作为数组字面量传递（API 会将地址解析为各个组成部分）：

address: {
  addressLines: ['1600 Amphitheatre Parkway, Mountain View, CA 94043'],
}

处理结果

fetchAddressValidation 方法会返回一个解析为 AddressValidationResponse 对象的 promise。此对象包含经过验证的地址，包括 API 进行的任何更正。您可以访问响应对象的各个字段，以确定地址的验证状态。以下示例展示了如何访问响应对象的字段。 

async function validateAddress() {
  // Import the Address Validation library.
  const {AddressValidation} =
      await google.maps.importLibrary('addressValidation');
  // Call the fetchAddressValidation method.
  const result = await AddressValidation.fetchAddressValidation({
    address: {
      postalCode: '94043',
      regionCode: 'US',
      languageCode: 'en',
      addressLines: ['1600 Amphitheatre', 'Parkway'],
    }
  });
  // Log the results to the console:
  console.log(`Formatted address: ${result.address.formattedAddress}`);
  console.log(`Entered: ${result.verdict.inputGranularity}`);
  console.log(`Validated: ${result.verdict.validationGranularity}`);
  console.log(`Address complete: ${result.verdict.addressComplete}`);
  console.log(`Has unconfirmed components: ${result.verdict.hasUnconfirmedComponents}`);
  console.log(`Has inferred components: ${result.verdict.hasInferredComponents}`);
  console.log(`Has replaced components: ${result.verdict.hasReplacedComponents}`);
}
