Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to obtain a ustruct from a json with an array

Hello everyone,

I'm currently trying to get this json:

 {
     "errors": [
         {
             "details": "Wrong username"
         },
         {
            "details": "Wrong email"
         }
     ]
 }

to work with this UStruct:

 USTRUCT()
 struct FResponse_Error {
     GENERATED_BODY()
         UPROPERTY() FString details;
     FResponse_Error() {}
 };

through c++ methods

  FJsonObjectConverter::JsonArrayStringToUStruct<FResponse_Error>(Response->GetContentAsString(), &errorResponse, 0, 0);

but with no succes, I looked for tutorials about ue4 and json but there isn't much information about it, i had succes getting json like this one

 {
     "username": "qwerty",
     "password": "qwerty"
 }

to work with one of my structs but I struggle to work with any json which has an array of json or nested json

Any anwser is welcome! Thanks in advance

Solved it!

Ustructs utilized:

 USTRUCT()
 struct FErrorsDetail {
     GENERATED_BODY()
         UPROPERTY() FString details;
     FErrorsDetail () {}
 };
 
 USTRUCT()
 struct FResponse_Error {
     GENERATED_BODY()
         UPROPERTY() TArray<Ferrors> errors;
     FResponse_Error() {}
 };

Code:

 FResponse_Error errorResponse;
         FJsonObjectConverter::JsonObjectStringToUStruct<FResponse_Error >(Response->GetContentAsString(), &errorResponse, 0, 0);
