Overview ¶
Package resty provides simple HTTP and REST client for Go inspired by Ruby rest-client.
Example (ClientCertificates) ¶
package main import ( "crypto/tls" "log" "github.com/go-resty/resty" ) func main() { // Parsing public/private key pair from a pair of files. The files must contain PEM encoded data. cert, err := tls.LoadX509KeyPair("certs/client.pem", "certs/client.key") if err != nil { log.Fatalf("ERROR client certificate: %s", err) } resty.SetCertificates(cert) }
Output:
Example (CustomRootCertificate) ¶
package main import ( "github.com/go-resty/resty" ) func main() { resty.SetRootCertificate("/path/to/root/pemFile.pem") }
Output:
Example (DropboxUpload) ¶
package main import ( "fmt" "io/ioutil" "os" "github.com/go-resty/resty" ) type DropboxError struct { Error string } func main() { // For example: upload file to Dropbox // POST of raw bytes for file upload. file, _ := os.Open("/Users/jeeva/mydocument.pdf") fileBytes, _ := ioutil.ReadAll(file) // See we are not setting content-type header, since go-resty automatically detects Content-Type for you resp, err := resty.R(). SetBody(fileBytes). // resty autodetects content type SetContentLength(true). // Dropbox expects this value SetAuthToken("<your-auth-token>"). SetError(DropboxError{}). Post("https://content.dropboxapi.com/1/files_put/auto/resty/mydocument.pdf") // you can use PUT method too dropbox supports it // Output print fmt.Printf("\nError: %v\n", err) fmt.Printf("Time: %v\n", resp.Time()) fmt.Printf("Body: %v\n", resp) }
Output:
Example (EnhancedGet) ¶
package main import ( "fmt" "strconv" "time" "github.com/go-resty/resty" ) func main() { resp, err := resty.R(). SetQueryParams(map[string]string{ "page_no": "1", "limit": "20", "sort": "name", "order": "asc", "random": strconv.FormatInt(time.Now().Unix(), 10), }). SetHeader("Accept", "application/json"). SetAuthToken("BC594900518B4F7EAC75BD37F019E08FBC594900518B4F7EAC75BD37F019E08F").

resty.SetError(&Error{}) // OR resty.SetError(Error{})
func (*Client) SetFormData ¶
SetFormData method sets Form parameters and its values in the client instance. It's applicable only HTTP method `POST` and `PUT` and requets content type would be set as `application/x-www-form-urlencoded`. These form data will be added to all the request raised from this client instance. Also it can be overridden at request level form data, see `resty.R().SetFormData`.
resty.SetFormData(map[string]string{ "access_token": "BC594900-518B-4F7E-AC75-BD37F019E08F", "user_id": "3455454545", })

func (*Client) SetMode ¶
SetMode method sets go-resty client mode to given value such as 'http' & 'rest'.
RESTful: - No Redirect - Automatic response unmarshal if it is JSON or XML HTML: - Up to 10 Redirects - No automatic unmarshall. Response will be treated as `response.String()`
If you want more redirects, use FlexibleRedirectPolicy
resty.SetRedirectPolicy(FlexibleRedirectPolicy(20))
func (*Client) SetOutputDirectory ¶ added in v0.4.1
SetOutputDirectory method sets output directory for saving HTTP response into file. If the output directory not exists then resty creates one. This setting is optional one, if you're planning using absoule path in `Request.SetOutput` and can used together.
resty.SetOutputDirectory("/save/http/response/here")
func (*Client) SetProxy ¶
SetProxy method sets the Proxy URL and Port for resty client.
resty.SetProxy("http://proxyserver:8888")
Alternative: Without this `SetProxy` method, you can also set Proxy via environment variable. By default `Go` uses setting from `HTTP_PROXY`.
func (*Client) SetQueryParam ¶
SetQueryParam method sets single paramater and its value in the client instance. It will be formed as query string for the request. For example: `search=kitchen%20papers&size=large` in the URL after `?` mark. These query params will be added to all the request raised from this client instance.

func (*Client) SetRootCertificate ¶ added in v0.4.1
SetRootCertificate method helps to add one or more root certificates into resty client
resty.SetRootCertificate("/path/to/root/pemFile.pem")
func (*Client) SetTLSClientConfig ¶
SetTLSClientConfig method sets TLSClientConfig for underling client Transport.
For example:
// One can set custom root-certificate. Refer: http://golang.org/pkg/crypto/tls/#example_Dial resty.SetTLSClientConfig(&tls.Config{ RootCAs: roots }) // or One can disable security check (https) resty.SetTLSClientConfig(&tls.Config{ InsecureSkipVerify: true })
Note: This method overwrites existing `TLSClientConfig`.
type RedirectPolicy ¶
RedirectPolicy to regulate the redirects in the resty client. Objects implementing the RedirectPolicy interface can be registered as
Apply function should return nil to continue the redirect jounery, otherwise return error to stop the redirect.
func DomainCheckRedirectPolicy ¶
func DomainCheckRedirectPolicy(hostnames ...string) RedirectPolicy
DomainCheckRedirectPolicy is convenient method to define domain name redirect rule in resty client. Redirect is allowed for only mentioned host in the policy.
resty.SetRedirectPolicy(DomainCheckRedirectPolicy("host1.com", "host2.org", "host3.net"))
func FlexibleRedirectPolicy ¶
func FlexibleRedirectPolicy(noOfRedirect int) RedirectPolicy
FlexibleRedirectPolicy is convenient method to create No of redirect policy for HTTP client.
resty.SetRedirectPolicy(FlexibleRedirectPolicy(20))
func NoRedirectPolicy ¶
func NoRedirectPolicy() RedirectPolicy

type Request ¶
type Request struct { URL string Method string QueryParam url.Values FormData url.Values Header http.Header UserInfo *User Token string Body interface{} Result interface{} Error interface{} Time time.Time RawRequest *http.Request // contains filtered or unexported fields }
Request type is used to compose and send individual request from client go-resty is provide option override client level settings such as
Auth Token, Basic Auth credentials, Header, Query Param, Form Data, Error object
and also you can add more options for that particular request
func R ¶
func R() *Request
R creates a new resty request object, it is used form a HTTP/RESTful request such as GET, POST, PUT, DELETE, HEAD, PATCH and OPTIONS.
func (*Request) Delete ¶
Delete method does DELETE HTTP request. It's defined in section 4.3.5 of RFC7231.
func (*Request) Execute ¶ added in v0.4.1
Execute method performs the HTTP request with given HTTP method and URL for current `Request`.
resp, err := resty.R().Execute(resty.GET, "http://httpbin.org/get")

func (*Request) Post ¶
Post method does POST HTTP request. It's defined in section 4.3.3 of RFC7231.
func (*Request) SetAuthToken ¶
SetAuthToken method sets bearer auth token header in the current HTTP request. For Header exmaple:
Authorization: Bearer <auth-token-value-comes-here>
For example: To set auth token BC594900518B4F7EAC75BD37F019E08FBC594900518B4F7EAC75BD37F019E08F
resty.R().SetAuthToken("BC594900518B4F7EAC75BD37F019E08FBC594900518B4F7EAC75BD37F019E08F")
This method overrides the Auth token set by method `resty.SetAuthToken`.
func (*Request) SetBasicAuth ¶
SetBasicAuth method sets the basic authentication header in the current HTTP request. For Header example:
Authorization: Basic <base64-encoded-value>
To set the header for username "go-resty" and password "welcome"
resty.R().SetBasicAuth("go-resty", "welcome")
This method overrides the credentials set by method `resty.SetBasicAuth`.
func (*Request) SetBody ¶
SetBody method sets the request body for the request. It supports various realtime need easy. We can say its quite handy or powerful. Supported request body data types is `string`, `[]byte`, `struct` and `map`. Body value can be pointer or non-pointer. Automatic marshalling for JSON and XML content type, if it is `struct` or `map`.
For Example:
Struct as a body input, based on content type, it will be marshalled.
resty.R(). SetBody(User{ Username: "jeeva@myjeeva.com", Password: "welcome2resty", })
Map as a body input, based on content type, it will be marshalled.
resty.R(). SetBody(map[string]interface{}{ "username": "jeeva@myjeeva.com", "password": "welcome2resty", "address": &Address{ Address1: "1111 This is my street", Address2: "Apt 201", City: "My City", State: "My State", ZipCode: 00000, }, })
String as a body input. Suitable for any need as a string input.
resty.R(). SetBody(`{ "username": "jeeva@getrightcare.com", "password": "admin" }`)
[]byte as a body input. Suitable for raw request such as file upload, serialize & deserialize, etc.
resty.R(). SetBody([]byte("This is my raw request, sent as-is"))
func (*Request) SetContentLength ¶
SetContentLength method sets the HTTP header `Content-Length` value for current request. By default go-resty won't set `Content-Length`. Also you have an option to enable for every request. See `resty.SetContentLength`
resty.R().SetContentLength(true)
func (*Request) SetError ¶
SetError method is to register the request `Error` object for automatic unmarshalling in the RESTful mode if response status code is greater than 399 and content type either JSON or XML.
Note: Error object can be pointer or non-pointer.
resty.R().SetError(&AuthError{}) // OR resty.R().SetError(AuthError{})
Accessing a error value
response.Error().(*AuthError)
func (*Request) SetFile ¶
SetFile method is to set single file field name and its path for multipart upload.
resty.R(). SetFile("my_file", "/Users/jeeva/Gas Bill - Sep.pdf")
func (*Request) SetFiles ¶
SetFiles method is to set multiple file field name and its path for multipart upload.
resty.R(). SetFiles(map[string]string{ "my_file1": "/Users/jeeva/Gas Bill - Sep.pdf", "my_file2": "/Users/jeeva/Electricity Bill - Sep.pdf", "my_file3": "/Users/jeeva/Water Bill - Sep.pdf", })
func (*Request) SetFormData ¶
SetFormData method sets Form parameters and its values in the current request. It's applicable only HTTP method `POST` and `PUT` and requets content type would be set as `application/x-www-form-urlencoded`.
resty.R(). SetFormData(map[string]string{ "access_token": "BC594900-518B-4F7E-AC75-BD37F019E08F", "user_id": "3455454545", })
Also you can override form data value, which was set at client instance level
func (*Request) SetHeader ¶
SetHeader method is to set a single header field and its value in the current request. For Example: To set `Content-Type` and `Accept` as `application/json`.
resty.R(). SetHeader("Content-Type", "application/json"). SetHeader("Accept", "application/json")
Also you can override header value, which was set at client instance level.
func (*Request) SetHeaders ¶
SetHeaders method sets multiple headers field and its values at one go in the current request. For Example: To set `Content-Type` and `Accept` as `application/json`
resty.R(). SetHeaders(map[string]string{ "Content-Type": "application/json", "Accept": "application/json", })
Also you can override header value, which was set at client instance level.
func (*Request) SetOutput ¶ added in v0.4.1
SetOutput method sets the output file for current HTTP request. Current HTTP response will be saved into given file. It is similar to `curl -o` flag. Absoulte path or relative path can be used. If is it relative path then output file goes under the output directory, as mentioned in the `Client.SetOutputDirectory`.
resty.R(). SetOutput("/Users/jeeva/Downloads/ReplyWithHeader-v5.1-beta.zip"). Get("http://bit.ly/1LouEKr")
Note: In this scenario `Response.Body` might be nil.
func (*Request) SetQueryParam ¶
SetQueryParam method sets single paramater and its value in the current request. It will be formed as query string for the request. For example: `search=kitchen%20papers&size=large` in the URL after `?` mark.
resty.R(). SetQueryParam("search", "kitchen papers"). SetQueryParam("size", "large")
Also you can override query params value, which was set at client instance level
func (*Request) SetQueryParams ¶
SetQueryParams method sets multiple paramaters and its values at one go in the current request. It will be formed as query string for the request. For example: `search=kitchen%20papers&size=large` in the URL after `?` mark.
resty.R(). SetQueryParams(map[string]string{ "search": "kitchen papers", "size": "large", })
Also you can override query params value, which was set at client instance level
func (*Request) SetQueryString ¶ added in v0.4.1
SetQueryString method provides ability to use string as an input to set URL query string for the request.
Using String as an input
resty.R(). SetQueryString("productId=232&template=fresh-sample&cat=resty&source=google&kw=buy a lot more")
func (*Request) SetResult ¶
SetResult method is to register the response `Result` object for automatic unmarshalling in the RESTful mode if response status code is between 200 and 299 and content type either JSON or XML.
Note: Result object can be pointer or non-pointer.
resty.R().SetResult(&AuthToken{}) // OR resty.R().SetResult(AuthToken{})
Accessing a result value
response.Result().(*AuthToken)
type Response ¶
type Response struct { Body []byte ReceivedAt time.Time Request *Request RawResponse *http.Response // contains filtered or unexported fields }
Response is an object represents executed request and its values.
func (*Response) Error ¶
func (r *Response) Error() interface{}
Error method returns the error object if it has one
func (*Response) Result ¶
func (r *Response) Result() interface{}
Result method returns the response value as an object if it has one
func (*Response) Size ¶ added in v0.4.1
Size method returns the HTTP response size in bytes. Ya, you can relay on HTTP `Content-Length` header, however it won't be good for chucked transfer/compressed response. Since Resty calculates response size at the client end. You will get actual size of the http response.
func (*Response) Status ¶
Status method returns the HTTP status string for the executed request.
For example: 200 OK
func (*Response) StatusCode ¶
StatusCode method returns the HTTP status code for the executed request.
For example: 200
