Nasty geschachtelte JSON zu Datenrahmen in R

Question

Ich habe ein paar JSON-Eingänge wie folgt.

Input1:

{"booking":{"id":"54092","createdOn":"2016-10-06T06:29:00.0000000+0000","bookingDateTime":"2016-10-08T06:45:00.0000000+0000","checkInDateTime":null,"checkOutDateTime":null,"tableNumbers":null,"pax":3,"type":"calling","status":"booked","source":"concierge","specialInstruction":"test hoppi","outlet":{"id":"46a97c2e-c921-4339-819c-50e17f25d09a","name":"Hoppipolla"},"customer":{"name":"Hoppi","email":"hoppi@xmail.com","countryCallingCode":"91","phone":"89"}},"eventType":"booked","serverDateTime":"2016-10-06T06:28:25.0000558+0000"} 

{"booking":{"id":"54093","createdOn":"2016-10-06T06:30:00.0000000+0000","bookingDateTime":"2016-10-08T06:46:00.0000000+0000","checkInDateTime":null,"checkOutDateTime":null,"tableNumbers":null,"pax":3,"type":"calling","status":"booked","source":"concierge","specialInstruction":"test hoppi","outlet":{"id":"46a97c2e-c922-4339-819c-50e17f25d09a","name":"Hoppipolla"},"customer":{"name":"Ravi","email":"ravi@xmail.com","countryCallingCode":"91","phone":"89"}},"eventType":"booked","serverDateTime":"2016-10-06T06:28:25.0000558+0000"} 

Input2:

{"feedback":{"dateTime":"2016-10-06T09:24:05.0000730+0000","customerName":"mytestdevcog","averageRating":4,"isNegativeByComments":false,"outlet":{"id":"f9e9c21f-2e52-462e-a1f2-012dab216d27","name":"cholan 's Darbar"},"customer":{"name":"mytestdevcog","email":"mytestdevcog123@gmail.com","countryCallingCode":"91","phone":"7895478745"},"responses":[{"question":"Was your waiting time too long?","response":"No","questionType":"yes_no"},{"question":"Service","response":"3","questionType":"rating"},{"question":"desserts","response":"4","questionType":"rating"},{"question":"Comments","response":"good","questionType":"short_answer"},{"question":"How likely is it that you would recommend us to a friend or colleague?","response":"5","questionType":"nps"},{"question":"Portion Size","response":"5","questionType":"rating"},{"question":"Indian Food","response":"4","questionType":"rating"},{"question":"Desert spread","response":"4","questionType":"rating"}]},"serverDateTime":"2016-10-06T09:24:27.0000644+0000"} 

{"feedback":{"dateTime":"2016-10-06T09:24:05.0000730+0000","customerName":"mytestdevcog","averageRating":4,"isNegativeByComments":false,"outlet":{"id":"f9e9c21f-2e52-462e-a1f2-012dab216d27","name":"cholan 's Darbar"},"customer":{"name":"mytestdevcog","email":"mytestdevcog123@gmail.com","countryCallingCode":"91","phone":"7895478745"},"responses":[{"question":"Was your waiting time too long?","response":"No","questionType":"yes_no"},{"question":"Service","response":"3","questionType":"rating"},{"question":"desserts","response":"4","questionType":"rating"},{"question":"Comments","response":"good","questionType":"short_answer"},{"question":"How likely is it that you would recommend us to a friend or colleague?","response":"5","questionType":"nps"},{"question":"Portion Size","response":"5","questionType":"rating"},{"question":"Indian Food","response":"4","questionType":"rating"},{"question":"Desert spread","response":"4","questionType":"rating"}]},"serverDateTime":"2016-10-06T09:24:27.0000644+0000"} 

Würden zwei separate Datenrahmen für zwei Eingänge benötigen. Wie kann dies in R erreicht werden?

Answer 1

Wie in den Kommentaren richtig angegeben, enthält Ihr json einen Fehler. Die dritte und vierte Saite enthalten tatsächlich "cholan's darbar", die entschlüsselt werden müssen, bevor Sie sie als json analysieren können.

Für Ihre Frage (über das Erhalten der zwei Datensätze) korrigierte ich direkt die Zeichenkette. Hier ist, wie es getan werden könnte:

library(jsonlite) 

s1 <- '{"booking":{"id":"54092","createdOn":"2016-10-06T06:29:00.0000000+0000","bookingDateTime":"2016-10-08T06:45:00.0000000+0000","checkInDateTime":null,"checkOutDateTime":null,"tableNumbers":null,"pax":3,"type":"calling","status":"booked","source":"concierge","specialInstruction":"test hoppi","outlet":{"id":"46a97c2e-c921-4339-819c-50e17f25d09a","name":"Hoppipolla"},"customer":{"name":"Hoppi","email":"hoppi@xmail.com","countryCallingCode":"91","phone":"89"}},"eventType":"booked","serverDateTime":"2016-10-06T06:28:25.0000558+0000"}' 

s2 <- '{"booking":{"id":"54093","createdOn":"2016-10-06T06:30:00.0000000+0000","bookingDateTime":"2016-10-08T06:46:00.0000000+0000","checkInDateTime":null,"checkOutDateTime":null,"tableNumbers":null,"pax":3,"type":"calling","status":"booked","source":"concierge","specialInstruction":"test hoppi","outlet":{"id":"46a97c2e-c922-4339-819c-50e17f25d09a","name":"Hoppipolla"},"customer":{"name":"Ravi","email":"ravi@xmail.com","countryCallingCode":"91","phone":"89"}},"eventType":"booked","serverDateTime":"2016-10-06T06:28:25.0000558+0000"}' 

in den folgenden zwei Saiten, die ich manuell "cholan des Darbar" korrigiert "cholan \ 's Darbar"

s3 <- '{"feedback":{"dateTime":"2016-10-06T09:24:05.0000730+0000","customerName":"mytestdevcog","averageRating":4,"isNegativeByComments":false,"outlet":{"id":"f9e9c21f-2e52-462e-a1f2-012dab216d27","name":"cholan \'s Darbar"},"customer":{"name":"mytestdevcog","email":"mytestdevcog123@gmail.com","countryCallingCode":"91","phone":"7895478745"},"responses":[{"question":"Was your waiting time too long?","response":"No","questionType":"yes_no"},{"question":"Service","response":"3","questionType":"rating"},{"question":"desserts","response":"4","questionType":"rating"},{"question":"Comments","response":"good","questionType":"short_answer"},{"question":"How likely is it that you would recommend us to a friend or colleague?","response":"5","questionType":"nps"},{"question":"Portion Size","response":"5","questionType":"rating"},{"question":"Indian Food","response":"4","questionType":"rating"},{"question":"Desert spread","response":"4","questionType":"rating"}]},"serverDateTime":"2016-10-06T09:24:27.0000644+0000"}' 

s4 <- '{"feedback":{"dateTime":"2016-10-06T09:24:05.0000730+0000","customerName":"mytestdevcog","averageRating":4,"isNegativeByComments":false,"outlet":{"id":"f9e9c21f-2e52-462e-a1f2-012dab216d27","name":"cholan \'s Darbar"},"customer":{"name":"mytestdevcog","email":"mytestdevcog123@gmail.com","countryCallingCode":"91","phone":"7895478745"},"responses":[{"question":"Was your waiting time too long?","response":"No","questionType":"yes_no"},{"question":"Service","response":"3","questionType":"rating"},{"question":"desserts","response":"4","questionType":"rating"},{"question":"Comments","response":"good","questionType":"short_answer"},{"question":"How likely is it that you would recommend us to a friend or colleague?","response":"5","questionType":"nps"},{"question":"Portion Size","response":"5","questionType":"rating"},{"question":"Indian Food","response":"4","questionType":"rating"},{"question":"Desert spread","response":"4","questionType":"rating"}]},"serverDateTime":"2016-10-06T09:24:27.0000644+0000"}'
