路径参数
参数 |
mapType |
enum (MapType )

允许的值:0-16
|
x |
integer
必需。定义所请求的图块中的东西点。
|
y |
integer
必需。定义所请求的图块中的南北点。

响应正文
表示任意 HTTP 正文的消息。它应仅用于无法表示为 JSON 的负载格式,例如原始二进制文件或 HTML 网页。
此消息可同时用于请求和响应中的流式传输和非流式传输 API 方法。
它可以用作顶级请求字段,如果想要将网址或 HTTP 模板中的参数提取到请求字段中,并且还希望访问原始 HTTP 正文,这会很方便。
示例:
message GetResourceRequest {
// A unique request id.
string request_id = 1;
// The raw HTTP body is bound to this field.
google.api.HttpBody http_body = 2;
}
service ResourceService {
rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);
rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);
}
流式传输方法示例:
service CaldavService {
rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);
rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);
}
使用此类型仅会更改请求和响应正文的处理方式,所有其他功能将继续保持不变。
如果成功,则响应为通用 HTTP 响应,其格式由方法定义。

{
"contentType": string,

字段 |
contentType |
string
指定正文内容类型的 HTTP Content-Type 标头值。
|
data |
string (bytes format)
作为原始二进制文件的 HTTP 请求/响应正文。 base64 编码的字符串。
|
extensions[] |
object
应用专用响应元数据。必须在流式传输 API 的第一个响应中设置。
此对象可以包含任意类型的字段。附加字段 "@type" 包含用于标示相应类型的 URI。示例:{ "id": 1234, "@type": "types.example.com/standard/id" } 。

It should only be used for payload formats that can't be represented as JSON, such as raw binary or an HTML page.\n\nThis message can be used both in streaming and non-streaming API methods in the request as well as the response.\n\nIt can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.\n\nExample: \n\n message GetResourceRequest {\n // A unique request id.\n string request_id = 1;\n\n // The raw HTTP body is bound to this field.\n google.api.HttpBody http_body = 2;\n\n }\n\n service ResourceService {\n rpc GetResource(GetResourceRequest)\n returns (google.api.HttpBody);\n rpc UpdateResource(google.api.HttpBody)\n returns (google.protobuf.Empty);\n\n }\n\nExample with streaming methods: \n\n service CaldavService {\n rpc GetCalendar(stream google.api.HttpBody)\n returns (stream google.api.HttpBody);\n rpc UpdateCalendar(stream google.api.HttpBody)\n returns (stream google.api.HttpBody);\n\n }\n\nUse of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.\n\nIf successful, the response is a generic HTTP response whose format is defined by the method.\n\n| JSON representation |\n|------------------------------------------------------------------------------------------------------------|\n| ``` { \"contentType\": string, \"data\": string, \"extensions\": [ { \"@type\": string, field1: ..., ... } ] } ``` |\n\n| Fields ||\n|----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `contentType` | `string` The HTTP Content-Type header value specifying the content type of the body. |\n| `data` | `string (`[bytes](https://developers.google.com/discovery/v1/type-format)` format)` The HTTP request/response body as raw binary. A base64-encoded string. |\n| `extensions[]` | `object` Application specific response metadata. Must be set in the first response for streaming APIs. An object containing fields of an arbitrary type. An additional field `\"@type\"` contains a URI identifying the type. Example: `{ \"id\": 1234, \"@type\": \"types.example.com/standard/id\" }`. |\n\n### Authorization scopes\n\nRequires the following OAuth scope:\n\n- `https://www.googleapis.com/auth/cloud-platform`\n\nFor more information, see the [OAuth 2.0 Overview](https://developers.google.com/identity/protocols/OAuth2).\n\nMapType\n-------\n\nThe type of the pollen heatmap.
