由于此示例计算的是从路线起点到每个地点的时长和距离，因此响应中的 routingSummaries.legs 字段包含一个 Leg 对象，该对象包含从路线起点到相应地点的 duration 和 distanceMeters。

Pass the `routingParameters.origin` parameter in the request to specify the\n latitude and longitude coordinates of the routing origin. This parameter is\n required to calculate the duration and distance to each place in the\n response.\n\n2. Include `routingSummaries` in the field mask so that the response includes\n the `routingSummaries` array. This array contains the duration and distance\n from the routing origin to each place in the response.\n\n | **Note:** Adding `routingSummaries` in the field mask without also including either the `routingParameters.origin` parameter or the `searchAlongRouteParameters.polyline.encodedPolyline` parameter in the request causes an error.\n\nThe APIs Explorer lets you make live requests so that you can get familiar with\nthe API and the API options: \n[Try it!](#try_it)\n\nUse Text Search (New)\n---------------------\n\nIn the following request, you calculate the travel duration and distance to each\nplace in the Text Search (New) response: \n\n```scdoc\ncurl -X POST -d '{\n \"textQuery\" : \"Spicy Vegetarian Food in Sydney, Australia\",\n \"routingParameters\": {\n \"origin\": {\n \"latitude\": -33.8688,\n \"longitude\": 151.1957362\n }\n }\n}' \\\n-H 'Content-Type: application/json' -H 'X-Goog-Api-Key: API_KEY' \\\n-H 'X-Goog-FieldMask: places.displayName,places.formattedAddress,places.priceLevel,routingSummaries' \\\n'https://places.googleapis.com/v1/places:searchText'\n```\n\nThe response contains two JSON arrays: the `places` array contains the matching\nplaces, and the `routingSummaries` array containing the duration and distance to\ntravel to each place: \n\n```yaml\n{\n \"places\": [\n {\n object (/maps/documentation/places/web-service/reference/rest/v1/places)\n }\n ]\n \"routingSummaries\": [\n {\n object (/maps/documentation/places/web-service/reference/rest/v1/RoutingSummary)\n }\n}\n```\n\nEach element in the `routingSummaries` array is at the corresponding array\nlocation as the place in the `places` array. That is, the element at\n`routingSummaries[0]` corresponds to the place at `places[0]`.\n\nThe array length of `routingSummaries` is the same as the array length of\n`places`. In the case where the `routingSummary` for a place is not available,\nthe array entry is empty.\n\nBecause this example calculates the duration and distance from the routing\norigin to each place, the `routingSummaries.legs` field in the response contains a single\n`Leg` object that contains the `duration` and `distanceMeters` from\nthe routing origin to the place.\n| **Note:** This response also includes the Preview (pre-GA) `directionsUri` field in the routing summary for each place. This field contains a link to open directions to the place in Google Maps. The `routingParameters.origin` parameter is used as the directions origin, the place location is used as the destination, and the travel mode defaults to drive.\n| This product or feature is in Preview (pre-GA). Pre-GA products and features might have limited support, and changes to pre-GA products and features might not be compatible with other pre-GA versions.

This example searches for restaurants in Sydney,\nAustralia and sets the location restriction and the routing origin to the same\nlatitude and longitude coordinate: \n\n```scdoc\n curl -X POST -d '{\n \"includedTypes\": [\"restaurant\"],\n \"maxResultCount\": 10,\n \"locationRestriction\": {\n \"circle\": {\n \"center\": {\n \"latitude\": -33.8688,\n \"longitude\": 151.1957362},\n \"radius\": 500.0\n }\n },\n \"routingParameters\": {\n \"origin\": {\n \"latitude\": -33.8688,\n \"longitude\": 151.1957362\n }\n }\n }' \\\n -H 'Content-Type: application/json' -H \"X-Goog-Api-Key:API_KEY\" \\\n -H \"X-Goog-FieldMask: places.displayName,routingSummaries\" \\\n https://places.googleapis.com/v1/places:searchNearby\n```\n\nYou don't have to use the same coordinates for the `locationRestriction` and the\nfor routing origin. For example, you set the `locationRestriction` to the center\npoint of Sydney to bias the search results to that circle. But you then set the\nrouting origin to the coordinates of your house, meaning to a different location\nwithin the search circle. The request then biases the search results to the\ncircle, and calculates the routing summaries based on the location of your\nhouse.\n\nSpecify travel options\n----------------------\n\nBy default, the duration and distance calculations are for a car. However, you\ncan control the vehicle type, as well as other options, in the search.\n\n- Use the `routingParameters.travelMode` parameter to set the mode of\n transportation to `DRIVE`, `BICYCLE`, `WALK`, or `TWO_WHEELER`. For more\n information on these options, see [Available vehicle types for\n routes](/maps/documentation/routes/vehicles).\n\n | **Note:** The Routes API also supports a mode of `TRANSIT`, but that mode is not supported by the Places API.\n | **Note:** The `TWO_WHEELER` option is only supported in those countries listed at [Countries and regions supported for two-wheeled\n | vehicles](/maps/documentation/routes/coverage-two-wheeled).\n- Use the `routingParameters.routingPreference` property to set the routing preference option to `TRAFFIC_UNAWARE` (default), `TRAFFIC_AWARE`, or `TRAFFIC_AWARE_OPTIMAL`. Each option has varying levels of data quality and latency. For more information, see [Specify how and if to include traffic\n data](/maps/documentation/routes/config_trade_offs).\n\n The `routingParameters.routingPreference` property does affect the\n directions contained in the Preview (Pre-GA) `directionsUri` field because\n Google Maps displays traffic options when it opens the link.\n- Use the `routingParameters.routeModifiers` property to specify to `avoidTolls`, `avoidHighways`, `avoidFerries`, and `avoidIndoor`. For more information on these options, see [Specify route features to\n avoid](/maps/documentation/routes/route-modifiers).\n\nIn the next example, you specify the travel mode as `DRIVE` and to avoid\nhighways: \n\n```scdoc\ncurl -X POST -d '{\n \"textQuery\" : \"Spicy Vegetarian Food in Sydney, Australia\",\n \"routingParameters\": {\n \"origin\": {\n \"latitude\": -33.8688,\n \"longitude\": 151.1957362\n },\n \"travelMode\":\"DRIVE\",\n \"routeModifiers\": {\n \"avoidHighways\": true\n }\n }\n}' \\\n-H 'Content-Type: application/json' -H 'X-Goog-Api-Key: API_KEY' \\\n-H 'X-Goog-FieldMask: places.displayName,places.formattedAddress,places.priceLevel,routingSummaries' \\\n'https://places.googleapis.com/v1/places:searchText'\n```\n\nTry it!\n-------\n\nThe APIs Explorer lets you make sample requests so\nthat you can get familiar with the API and the API options.\n\n1. Select the API icon api\n on the right side of the page.\n\n2. Optionally edit the request parameters.\n\n3. Select the **Execute** button.
