Android: Unable to convert string to JsonArray-CodePudding

I have a json which is getting returned as array but I'm unable to convert it into a list. The string looks like:

"[{\"@context\":[\"v1\"],\"id\":\"did\",\"type\":[\"VerifiableCredential\"],\"issuer\":\"did\",\"issuanceDate\":\"2022-07-27T10:24:48Z\",\"expirationDate\":\"2023-07-27T10:24:48Z\",\"credentialSchema\":{\"id\":\"didversion=0.2\",\"type\":\"JsonSchemaValidator2018\"},\"credentialSubject\":{\"contact\":\"[email protected]\",\"name\":\"Fedex\",\"orgId\":\"fedex\",\"privacyPolicy\":\"privacy-policy\",\"services\":[{\"purposes\":[{\"purpose\":\"To get my Health Insights data into my wallet.\"}],\"service\":\"download\"}],\"technical\":{\"download\":{\"id\":\"DOQQ163002\",\"linkId\":\"c97b8411-a6ba-4955-88e7-071353fbc2b8\",\"passcode\":\"2a57c0cd-b036-4c6f-9a41-adde8be8cc3e\",\"url\":\"attachments\"},\"symmetricKey\":{\"algorithm\":\"aes-256-cbc\",\"iv\":\"8qbl7cgPpuVzGrUSmt/Vsw==\",\"value\":\"3ROXMpHAEO8FNSVMzkTZIjnbFE7lD4T1FgwWs3B83JA=\"}},\"type\":\"profile\",\"userAgreement\":\"By agreeing to create this connection, I give Merative permission to request my data from Health Insights, credentialize it, and send it to my digital wallet.\",\"website\":\"com/\"},\"proof\":{\"created\":\"2022-07-27T10:24:48Z\",\"creator\":\"did\",\"nonce\":\"c6cd9a75-e8d2-468d-8305-427667ea778f\",\"signatureValue\":\"MEQCIAQd94Q4zE7OXLYdpWUW_eMBBtPBLEQGJ4DK8uNIJMxgAiBA3FGtmy67qwcpVyAdx3GqCa2X7LoCa5StR4G_EpIYRg\",\"type\":\"EcdsaSecp256r1Signature2019\"}},{\"@context\":[\"v1\"],\"id\":\"did\",\"type\":[\"VerifiableCredential\",\"ID\"],\"issuer\":\"did\",\"issuanceDate\":\"2022-07-27T10:24:48Z\",\"expirationDate\":\"2023-07-27T10:24:48Z\",\"credentialSchema\":{\"id\":\"did;version=0.2\",\"type\":\"JsonSchemaValidator2018\"},\"credentialSubject\":{\"birthDate\":\"1965-02-05\",\"email\":\"[email protected]\",\"gender\":\"M\",\"id\":\"DOQQ163002\",\"name\":{\"familyName\":\"Ireson\",\"givenName\":\"Davian\"},\"organization\":\"fedex\",\"ssn\":\"123456789\",\"type\":\"id\"},\"proof\":{\"created\":\"2022-07-27T10:24:48Z\",\"creator\":\"did\",\"nonce\":\"19766c23-5826-4226-98b3-8680db73cd09\",\"signatureValue\":\"MEUCIBdmLk3Xh\",\"type\":\"EcdsaSecp256r1Signature2019\"}}]"

I have tried following approach but it's not working for me.

val myModelList: List<Model> = gson.fromJson(s.toJsonElement(), mutableListOf<Model>().javaClass)

Can anyone please let me know how I can convert this string to Json and then into List?

CodePudding user response：

The returned json format seems to be incorrect.

CodePudding user response：

It is very simple is kotlin, No need to replace anything : Follow mentioned code :

val t = "[{\"@context\":[\"v1\"],\"id\":\"did\",\"type\":[\"VerifiableCredential\"],\"issuer\":\"did\",\"issuanceDate\":\"2022-07-27T10:24:48Z\",\"expirationDate\":\"2023-07-27T10:24:48Z\",\"credentialSchema\":{\"id\":\"didversion=0.2\",\"type\":\"JsonSchemaValidator2018\"},\"credentialSubject\":{\"contact\":\"[email protected]\",\"name\":\"Fedex\",\"orgId\":\"fedex\",\"privacyPolicy\":\"privacy-policy\",\"services\":[{\"purposes\":[{\"purpose\":\"To get my Health Insights data into my wallet.\"}],\"service\":\"download\"}],\"technical\":{\"download\":{\"id\":\"DOQQ163002\",\"linkId\":\"c97b8411-a6ba-4955-88e7-071353fbc2b8\",\"passcode\":\"2a57c0cd-b036-4c6f-9a41-adde8be8cc3e\",\"url\":\"attachments\"},\"symmetricKey\":{\"algorithm\":\"aes-256-cbc\",\"iv\":\"8qbl7cgPpuVzGrUSmt/Vsw==\",\"value\":\"3ROXMpHAEO8FNSVMzkTZIjnbFE7lD4T1FgwWs3B83JA=\"}},\"type\":\"profile\",\"userAgreement\":\"By agreeing to create this connection, I give Merative permission to request my data from Health Insights, credentialize it, and send it to my digital wallet.\",\"website\":\"com/\"},\"proof\":{\"created\":\"2022-07-27T10:24:48Z\",\"creator\":\"did\",\"nonce\":\"c6cd9a75-e8d2-468d-8305-427667ea778f\",\"signatureValue\":\"MEQCIAQd94Q4zE7OXLYdpWUW_eMBBtPBLEQGJ4DK8uNIJMxgAiBA3FGtmy67qwcpVyAdx3GqCa2X7LoCa5StR4G_EpIYRg\",\"type\":\"EcdsaSecp256r1Signature2019\"}},{\"@context\":[\"v1\"],\"id\":\"did\",\"type\":[\"VerifiableCredential\",\"ID\"],\"issuer\":\"did\",\"issuanceDate\":\"2022-07-27T10:24:48Z\",\"expirationDate\":\"2023-07-27T10:24:48Z\",\"credentialSchema\":{\"id\":\"did;version=0.2\",\"type\":\"JsonSchemaValidator2018\"},\"credentialSubject\":{\"birthDate\":\"1965-02-05\",\"email\":\"[email protected]\",\"gender\":\"M\",\"id\":\"DOQQ163002\",\"name\":{\"familyName\":\"Ireson\",\"givenName\":\"Davian\"},\"organization\":\"fedex\",\"ssn\":\"123456789\",\"type\":\"id\"},\"proof\":{\"created\":\"2022-07-27T10:24:48Z\",\"creator\":\"did\",\"nonce\":\"19766c23-5826-4226-98b3-8680db73cd09\",\"signatureValue\":\"MEUCIBdmLk3Xh\",\"type\":\"EcdsaSecp256r1Signature2019\"}}]";
val a = JSONArray(t)
