go swag常用注释

生成在线文档校验接口时，主要使用这个@Param这种注解写对。个人理解，这些注释不是对代码功能的约束，而是对生成的前端测试ui中前端代码的约束。或者说对文档的约束

param的格式：
param name,param type,data type,is mandatory?,comment attribute(optional)

@Param enumstring query string false "string enums" Enums(A, B, C)

Param Type

• query
• path
• header
• body
• formData

Data Type

• string (string)
• integer (int, uint, uint32, uint64)
• number (float32)
• boolean (bool)
• user defined struct

Mime Types

主要在@accept【前端需要传哪个】、@produce【自己传给前端的是哪种】中使用

Alias	MIME Type
json	application/json
xml	text/xml
plain	text/plain
html	text/html
mpfd	multipart/form-data
x-www-form-urlencoded	application/x-www-form-urlencoded
json-api	application/vnd.api+json
json-stream	application/x-json-stream
octet-stream	application/octet-stream
png	image/png
jpeg	image/jpeg
gif	image/gif

值的数据约束

Field Name	Type	Description
validate	string	Determines the validation for the parameter. Possible values are: required.
default	*	Declares the value of the parameter that the server will use if none is provided, for example a “count” to control the number of results per page might default to 100 if not supplied by the client in the request. (Note: “default” has no meaning for required parameters.) See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-6.2. Unlike JSON Schema this value MUST conform to the defined type for this parameter.
maximum	number	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.1.2.
minimum	number	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.1.3.
maxLength	integer	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.2.1.
minLength	integer	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.2.2.
enums	[*]	See https://tools.ietf.org/html/draft-fge-json-schema-validation-00#section-5.5.1.
format	string	The extending format for the previously mentioned type. See Data Type Formats for further details.
collectionFormat	string	Determines the format of the array if type array is used. Possible values are:csv - comma separated values foo,bar.ssv - space separated values foo bar.tsv - tab separated values foo\tbar.pipes - pipe separated values foo|bar.multi - corresponds to multiple parameter instances instead of multiple values for a single instance foo=bar&foo=baz. This is valid only for parameters in “query” or “formData”.Default value is csv.
