The project needs to pack the relevant parameters in the body when the network request is made. Since this kind of operation is rarely encountered before, so make a record here. The specific code is as follows:
NSString *dicTojson = @"dictionary to string parameter";
NSString *url = [NSString stringWithFormat:@"%@VMS2Service.cgi?Cmd=%@",baseUrl, method];
NSData *body = [dicTojson dataUsingEncoding:NSUTF8StringEncoding]
NSMutableURLRequest *request = [[AFJSONRequestSerializer serializer]requestWithMethod:requestType URLString:url parameters:nil error:nil];
[request setHTTPMethod:requestType];
[request setValue:authToken forHTTPHeaderField:@"Auth-Token"];
[request setHTTPBody:body];
//Set the timeout
NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfig.timeoutIntervalForRequest = 15.0;
sessionConfig.timeoutIntervalForResource = 15.0;
NSURLSession *session = [NSURLSession sharedSession];；
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if(error==nil){
NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
if (failure) {
failure(errorMsg);
}
}else{
if(success){
success(dict);
}
}
}else{
if (failure) {
failure(@"server timeout");
}
}
} ];
[dataTask resume];
The AFN method can be used for reference: ios uses AFNetworking to pass the object as a parameter (put into the body) to the background - Short Book
