I have been trying to work this problem all day and can not resolve it.
I get some Json data from a restful service and after a res.readJson() store the data in a file. I then deserialize the data into a D struct. So far so good.
I placed the data in a file so I can use it for other processing. When I read the data from the file it will no longer deserialize into the D struct.
I have tried many variations throughout the day to no avail. The code snippets below are my last attempt.
Any assistance is deeply appreciated.
Thanks John
Json getDevices(string groupId) {
Json anEmptyDevice;
//anEmptyDevice.length = 1;
string completeURL = "xxxxxxxxxxxxxxxxxxxxxxx";
HTTPClientResponse res = requestHTTP(completeURL,(scope req) { req.method = HTTPMethod.GET; req.addBasicAuth("xxxx","xxxxx"); req.headers["Accept"] = "application/json"; });
if (res.statusCode != 200) {
logInfo("Check Internet connection, and try again!"); logInfo("Server response is: " ~ to!string(res.statusCode)); return anEmptyDevice;}
else {logInfo("return code was ok ",res.statusCode); auto theData = res.readJson(); File file = File("/home/john/Documents/pfGroups/deviceData", "w"); file.rawWrite(to!string(theData)); file.close(); return theData;}
}The following code calls the above code.
void main() {
auto theDevices = getDevices("c0cd774d-e27a-4d86-bad6-77e3400ea5c9");
auto myData = to!string(read("/home/john/Documents/pfGroups/deviceData"));
devices = deserializeJson!(Device[])(theDevices);// This fails with this error std.json.JSONException@../../../.dub/packages/vibe-d-0.7.29/source/vibe/data/json.d(1789): Expecting ',' or '}', not '"'.Device[] devices = deserializeJson!(Device[])(myData);
}THE DATA AS RETURNED FROM THE HTTP REQUEST amd WRITTEN TO THE FILE and it will deserialize

Resolved this. I was not serializing/deserializing the data. I have included message pack and use that to serialize/deserialize the data. Works great
Thanks
