i trying to parse JSON with NSJSONSerialization.
NSArray *a = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&err]; the error shows this: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Badly formed array around character 202.) UserInfo=0x9f79230 {NSDebugDescription=Badly formed array around character 202.}
here is the JSON code:
[
{
"ID":1,
"name":"sometext",
"c":"sometext",
"city":"sometext",
"street":"sometext",
"a":32.914671,
"b":35.292417,
"Info":"sometext",
"imageAddress":"images/aroma.jpeg"
}
{
"ID":2,
"name":"sometext",
"c":"sometext",
"city":"sometext",
"street":"sometext",
"a":4.224,
"b":72.1234,
"Info":"sometext",
"imageAddress":"images/"
}
where the JSON not coded currently?
In your JSON, array objects are not separated by comma
[
{
"ID":1,
"name":"sometext",
"c":"sometext",
"city":"sometext",
"street":"sometext",
"a":32.914671,
"b":35.292417,
"Info":"sometext",
"imageAddress":"images/aroma.jpeg"
},
{
"ID":2,
"name":"sometext",
"c":"sometext",
"city":"sometext",
"street":"sometext",
"a":4.224,
"b":72.1234,
"Info":"sometext",
"imageAddress":"images/"
}
]
This should work.

I've a response
{ errors: [
{
code: 123,
reason: "this is the cause for a random problem where the last part of this string is dynamically generated"
} ,
{
code: 234,
reason: "Some other error for another random reason"
}
...
...
}
Now when I validate this response
I use following
...
...
And match response.errors[*].reason contains "this is the cause"
This validation fails, because there is an equality check for complete String for every reason ,
I all I want is, to validate that inside the errors array, if there is any error object, which has a reason string type property, starting with this is the cause phrase.
I tried few wild cards but didn't work either, how to do it ?
For complex things like this, just switch to JS.
* def found = response.errors.find(x => x.reason.startsWith('this is the cause'))
* match found == { code: 123, reason: '#string' }
# you can also do
* if (found) karate.log('found')
Any questions :)
Could you help me with the following question?
I try to update the Customer Credit Limit in Acumatica:
Request:
PUT https://{Base_URL}/Customer?$select=CreditVerificationRules&$filter=CustomerID%20eq%20'0e31e8a5-08e3-ea11-a828-000d3ab2c384'
{
"CreditVerificationRules": {
"CreditLimit": {
"value": 1234.0
}
}
}
But I receive the following error:
Response: {"message":"An error has occurred.","exceptionMessage":"Syntax error: character '%' is not valid at position 10 in 'CustomerID%20eq%20'0e31e8a5-08e3-ea11-a828-000d3ab2c384'
Try it without the html encoding. I.e. CustomerID eq '0e31e8a5-08e3-ea11-a828-000d3ab2c384' FYI, if this was an instance where you needed html encoding, then you should have encoded the ' symbol as well.
In my app, I get the following response for a failed user login:
{
"non_field_errors": [
"User account is disabled."
]
}
Is there a way to get this in Objective-C to only display: User account is disabled.?
When I do the following, it displays:
(
"User account is disabled."
)
Code:
NSLog(#"%#",[JSONValue objectForKey:#"non_field_errors"]);
How can I remove the parentheses and double quotes?
Parentheses is there because you are getting response in such a way. you can access your data using following way.
JSONValue[#"non_field_errors"][0] // This will return User account is disabled.
That is because the value for key non_field_errors is a JSON Array (Notice the square brackets). So use this :
NSArray *arr = [JSONValue objectForKey:#"non_field_errors"];
NSLog(#"%#",[arr firstObject]);
or just cram it all in one line
[(NSArray*)[JSONValue objectForKey:#"non_field_errors"] firstObject];
I'm trying to get the directions using google directions but I'm getting this error :
Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Unrecognised
leading character (41)\
Here is the Json
loadDirections('Avenida Paulista', 'Rua Augusta', { 'locale': 'en', travelMode: G_TRAVEL_MODE_WALKING, avoidHighways: false, getPolyline: true, getSteps: true, preserveViewport: false})
Whats is wrong? Whats Unrecognised leading character (41) mean?
- (void)loadWithStartPoint:(NSString *)startPoint endPoint:(NSMutableArray *)endPoints options:(UICGDirectionsOptions *)options {
for (int idx = 0; idx < [endPoints count];idx ++)
{
NSString* msg = [NSString stringWithFormat:#"loadDirections('%#', '%#', %#)", startPoint, [endPoints objectAtIndex:idx], [options JSONRepresentation]];
NSLog(#"msg %#",msg);
mstr = [msg retain];
[self performSelector:#selector(loadDirections:) withObject:nil afterDelay:0.5];
}
}
-(void)loadDirections:(NSString *)message
{
[googleMapsAPI stringByEvaluatingJavaScriptFromString:mstr];
}
The JSON is invalid.
{
'locale': 'en',
travelMode: "G_TRAVEL_MODE_WALKING",
avoidHighways: false,
getPolyline: true,
getSteps: true,
preserveViewport: false
}
I think this has something to do with G_TRAVEL_MODE_WALKING, it should be in quotes. The only valid JSON values are as follows
Objects ({})
Arrays ([])
Value
String ("this is a string")
Number 1/-1
true
false
null
JSON Documentation
Make sure that, while initializing the GDirections object, you also pass an actual element as the second parameter.
As stated in the documentation:
The mode of travel, such as driving (default) or walking. Note that if
you specify walking directions, you will need to specify a panel
to hold a warning notice to users.
If you are using the Map-Kit-Route-Directions extensions, you just have to open the api.html file and, at line 16, substitute this
gdir = new GDirections(null, null);
with this
gdir = new GDirections(null, "body");
I am constructing a tuning fork app. The fork should allow up to 12 preset pitches.
Moreover, I wish to allow the user to choose a theme. Each theme will load a set of presets (not necessary to use all of them).
My configuration file would look something like this*:
theme: "A3"
comment: "An octave below concert pitch (ie A4 440Hz)"
presets: {
A3 220Hz=220.0
}
// http://en.wikipedia.org/wiki/Guitar_tuning
theme: "Guitar Standard Tuning"
comment:"EADGBE using 12-TET tuning"
presets: {
E2=82.41
A2=110.00
D3=146.83
G3=196.00
B3=246.94
E4=329.63
}
theme: "Bass Guitar Standard Tuning"
comment: "EADG using 12-TET tuning"
presets: {
E1=41.204
A2=55.000
D3=73.416
G3=97.999
}
...which need to be extracted into some structure like this:
#class Preset
{
NSString* label;
double freq;
}
#class Theme
{
NSString* label;
NSMutableArray* presets;
}
NSMutableArray* themes;
How do I write my file using JSON? ( I would like to create a minimum of typing on the part of the user -- how succinct can I get it? Could someone give me an example for the first theme? )
And how do I parse it into the structures using https://github.com/johnezang/JSONKit?
Here's a valid JSON example based on your thoughts:
[
{
"name": "Guitar Standard Tuning",
"comment": "EADGBE using 12-TET tuning",
"presets": {
"E2": "82.41",
"A2": "110.00",
"D3": "146.83",
"G3": "196.00",
"B3": "246.94",
"E4": "329.63"
}
},
{
"name": "Bass Guitar Standard Tuning",
"comment": "EADG using 12-TET tuning",
"presets": {
"E1": "41.204",
"A1": "55.000",
"D2": "73.416",
"G2": "97.999"
}
}
]
Read a file and parse using JSONKit:
NSData* jsonData = [NSData dataWithContentsOfFile: path];
JSONDecoder* decoder = [[JSONDecoder alloc]
initWithParseOptions:JKParseOptionNone];
NSArray* json = [decoder objectWithData:jsonData];
After that, you'll have to iterate over the json variable using a for loop.
Using the parser in your question and assuming you have Simeon's string in an NSString variable. Here's how to parse it:
#import "JSONKit.h"
id parsedJSON = [myJSONString objectFromJSONString];
That will give you a hierarchy of arrays and dictionaries that you can walk to get your Preset and Theme objects. In the above case, you would get an array with two dictionaries each with a name, comment and presets key. The first two will have NSString values and the third (presets) will have a dictionary as it's value with the note name as keys and the frequencies as values (as NSString objects).
