Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/correios|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == correios [[toc:]] === Description Correios is a Chicken Scheme library that implements shipping calculation (tax and estimated delivery time) for a Brazillian post office service with the same name. It is implemented according to the official [[http://www.correios.com.br/webServices/PDF/SCPP_manual_implementacao_calculo_remoto_de_precos_e_prazos.pdf|Correios web service specification]]. === Author [[/users/arthurmaciel|Arthur Maciel]] === Requirements Requires the [[defstruct]], [[http-client]], [[ssax]] and [[uri-common]] eggs and the [[srfi-1]] unit. === Documentation ==== Requests <procedure>(make-request #!key service from-zip to-zip (company "") (password "") (pkg-weight 0.3) (pkg-format 1) (pkg-length 16) (pkg-height 2) (pkg-breadth 11) (pkg-diameter 0) (receiver-id-check #f) (declared-value 0) (return-receipt #f) (return-url "XML"))</procedure> Create a correios {{request}} object (a [[defstruct]] record) to be processed. It has many attributes that correspond to the official [[http://www.correios.com.br/webServices/PDF/SCPP_manual_implementacao_calculo_remoto_de_precos_e_prazos.pdf|Correios web service specification]]: ; SERVICE: available delivery services: {{'PAC}}, {{'SEDEX}}, {{'SEDEX-10}}, {{'SEDEX-HOJE}} and {{'SEDEX-A-COBRAR}}. It can also be a list combining one or more of these symbols (ie. {{'(PAC SEDEX SEDEX-10)}}). ; FROM-ZIP: sender's zip code and should be a string with 8 digits (only numbers allowed). ; TO-ZIP: receiver's zip code and should be a string with 8 digits (only numbers allowed). ; COMPANY: company code, if yours has one. It should be a string. ; PASSWORD: company password, only if a company code is provided. It should be a string. ; PKG-WEIGHT: package weight in kilograms. Should be a number. ; PKG-FORMAT: package format and should be a number: 1 for box/package, 2 for roller/prism and 3 for envelope. ; PKG-LENGTH: package length in centimeters (including packing size) and should be a number. ; PKG-HEIGHT: package height in centimeters (including packing size) and should be a number. ; PKG-BREADTH: package breadth in centimeters (including packing size) and should be a number. ; PKG-DIAMETER: package diameter in centimeters (including packing size) and should be a number. ; RECEIVER-ID-CHECK: a boolean and determines whether the package should be delivered only to the receiver's hand (Correios calls this service "Mão própria"). ; DECLARED-VALUE: package declared value in Brazillian Reais, to be returned in case of miscarriage. It should be a number - ex.: {{33.50}} (default is {{0}}, which means no use of service). ; RETURN-RECEIPT: a boolean and determines whether the package should be delivered with additional service of a return receipt ({{#f}} means no use of the service). ; RETURN-URL: request return URL or type - at the moment can only be "XML". '''Note:''' although all values returned use Brazillian decimal notation with a comma separating cents from integers (ex.: {{3,25}}), all the decimal values provided to {{make-request}} should have a dot (ex.: {{3.25}}) separating those parts. <procedure>(update-request old-request #!key service from-zip to-zip company password pkg-weight pkg-format pkg-length pkg-height pkg-breadth pkg-diameter receiver-id-check declared-value return-receipt return-url)</procedure> Like make-request, except this takes an old-request object as a template for values which are missing from the parameter list, thereby providing a way to do a purely functional update of that object. <procedure>(process-request REQUEST)</procedure> This is the core procedure for shipping cost calculation. It accepts a {{request}} object as a parameter and returns a ''list'' of {{response}} objects. The list can be processed (see [[#examples|Examples]] below) and data can be extracted from each response using its accessors (see [[#responses|{{response}}]] details below). For each {{request}} attribute there is a respective accessor procedure: <procedure>(request-service REQUEST) => SERVICE</procedure> <procedure>(request-from-zip REQUEST) => FROM-ZIP</procedure> <procedure>(request-to-zip REQUEST) => TO-ZIP</procedure> <procedure>(request-company REQUEST) => COMPANY</procedure> <procedure>(request-password REQUEST) => PASSWORD</procedure> <procedure>(request-pkg-weight REQUEST) => PKG-WEIGHT</procedure> <procedure>(request-pkg-format REQUEST) => PKG-FORMAT</procedure> <procedure>(request-pkg-length REQUEST) => PKG-LENGTH</procedure> <procedure>(request-pkg-height REQUEST) => PKG-HEIGHT</procedure> <procedure>(request-pkg-breadth REQUEST) => PKG-BREADTH</procedure> <procedure>(request-pkg-diameter REQUEST) => PKG-DIAMETER</procedure> <procedure>(request-receiver-id-check REQUEST) => RECEIVER-ID-CHECK</procedure> <procedure>(request-declared-value REQUEST) => DECLARED-VALUE</procedure> <procedure>(request-return-receipt REQUEST) => RETURN-RECEIPT</procedure> <procedure>(request-return-url REQUEST) => RETURN-URL</procedure> ==== Responses <record>response</record> This is a correios shipping response object that is generated by {{process-request}}. It is a [[defstruct]] record and has a constructor {{make-response}} (used only internally). It has 10 attributes that can be retrieved using the respective accessor procedure: <procedure>(response-service RESPONSE) => SERVICE</procedure> Returns the delivery service type as a symbol - ie. {{'PAC}}, {{'SEDEX}} or {{SEDEX-10)}}. <procedure>(response-cost RESPONSE) => COST</procedure> Returns the total delivery cost in Brazillian Reais as a string - ie. {{"15,80"}}. <procedure>(response-delivery-time RESPONSE) => DELIVERY-TIME</procedure> Returns the delivery time in days as a number. <procedure>(response-receiver-id-check-cost RESPONSE) => RECEIVER-ID-CHECK-COST</procedure> Returns the cost of the {{receiver-id-check}} service (if used) in Brazillian Reais as a string - ie. {{"3,20"}}. <procedure>(response-return-receipt-cost RESPONSE) => RETURN-RECEIPT-COST</procedure> Returns the cost of the {{return-receipt-cost}} service (if used) in Brazillian Reais as a string - ie. {{"2,90"}}. <procedure>(response-declared-value-cost RESPONSE) => DECLARED-VALUE-COST</procedure> Returns the cost of {{declared-value}} service in Brazillian Reais as a string - ie. {{"32,50"}}. <procedure>(response-home-delivery RESPONSE) => HOME-DELIVERY</procedure> Returns a boolean indicating whether or not the {{home-delivery}} service is available (believe it or not there are still many inaccessible areas in Brazil!). <procedure>(response-saturday-delivery RESPONSE) => SATURDAY-DELIVERY</procedure> Returns a boolean indicating whether or not the {{saturday-delivery}} service is available. <procedure>(response-error RESPONSE) => ERROR</procedure> Returns {{"0"}} if there were no errors or other number (in a string format) if so (see pages 14 and 15 of the [[http://www.correios.com.br/webServices/PDF/SCPP_manual_implementacao_calculo_remoto_de_precos_e_prazos.pdf|Correios web service specification]] for a complete error code list). <procedure>(response-error-msg RESPONSE) => ERROR-MSG</procedure> Returns a {{#f}} if there were no errors or a string with the error message. There is also a procedure to check if there {{response}} generated by {{process-request}} is valid: <procedure>(valid-response? RESPONSE)</procedure> Check if a specific response has generated errors. Returns a boolean. === Examples <enscript highlight="scheme"> (use correios) ;; Create a request (define ship-req (make-request service: (list 'SEDEX 'PAC) from-zip: "05412002" to-zip: "90035120")) ;; Proccess it and iterate along the reponse list (let loop ((responses (process-request ship-req))) (cond ((null? responses) (printf "Finished processing responses.~N")) (else (let ((resp (car responses))) (if (valid-response? resp) (printf "Service ~A - Cost: R$~A Estimated delivery (days): ~A~N" (response-service resp) (response-cost resp) (response-delivery-time resp)) (printf "Service ~A - Error: ~A" (response-service resp) (response-error-msg resp)))) (loop (cdr responses))))) => Service SEDEX - Cost: R$33,00 Estimated delivery (days): 1 Service PAC - Cost: R$15,80 Estimated delivery (days): 4 Finished processing responses. </enscript> === Changelog * 0.1 Initial version === License Copyright (c) 2013, Arthur Maciel All rights reserved.
