There are 2 overload that accept

• int
• ArrayIndex

According to line 236,
https://github.com/jefftimesten/ofxJSON/blob/5934d7044406041d46c763d0509613ac71801256/libs/jsoncpp/include/json/json.h#L236

typedef unsigned int ArrayIndex;

ArrayIndex is unsigned int.

Now, I'm tried to pass std::size_t value but failed.
https://travis-ci.org/Lacty/ToTheTop/builds/195512607
Because gcc defines std::size_t as unsigned long

According to C standerd, unsigned long is bigger or same with unsigned int. So, overload resolution was failed.

Why don't you accept std::size_t?
All of operator[] defined at STL container can accept std::size_t.

There are two scenarios to solve that.

1. typedef std::size_t ArrayIndex;(breaking change!)
2. Add overload for std::size_t(Note: SFINAE is required to avoid conflict with Json::ArrayIndex. ex.) http://melpon.org/wandbox/permlink/V24WVUhGMvc7SjQH)

Asynchronous requests would be great!

Eyebeam is not mentioned neither in license.md nor in README.md thus it is not clear what rights are reserved to that company. In strict sense "All rights reserved" imposes more conservative limitations than MIT license. Could the intention of the cited lines be clarified?

Twitter now requires a authentication token for what those examples were doing.

Twitter example will not work at all anymore.

I've spent the past hour trying to get the examples to compile, but haven't had any luck. Are they compatible with the latest version of OF?

Hi,

Should this work with UTF-8 encoded files? If I try to open a file using json.open("file.json") that is UTF-8 encoded I get the following error:

ofxJSONElement::openLocal: Unable to parse file.json: * Line 1, Column 1
Syntax error: value, object or array expected.

If the same file is encoded as ANSI then it works fine.

I don't know if you've tried this addon on linux but I'm having trouble getting it through the precompiler. I've traced it down to the ofxJSON addon and the precompiler but haven't found a cause yet.

I can compile jsoncpp-0.5.0 using scons.

Errors are like:
In file included from /usr/include/c++/4.6/cstdio:44:0,
from /usr/include/c++/4.6/fstream:43,

from ../../z25-lib/unstable/openFrameworks/addons/../../ofAddons/ofxJSON/src/ofxJSONElement.cpp:10:
/usr/include/stdio.h:940:1: error: expected declaration before ‘}’ token

I'll do some more digging but just to let you know...:

I want to get weather info by ofxJson, but some info will get wrong state different with the right.

1.Link address: http://www.weather.com.cn/data/sk/101200101.html
2.Get "WD" info:
string city = nowJson["weatherinfo"]["city"].asString();
string WD = nowJson["weatherinfo"]["WD"].asString();
translate to the wstring..
3.Can not get right info, but get the info "武汉" which should be get by "city".

Maybe it's my incorrect operation.
Wish to get your replay, thx.

Hi,

I would like to write the OF objects like ofImage in json format and read them as ofImage. How can I do this?

Regards

Can I assume that ofxJSON is MIT licensed as same as JsonCpp? Otherwise, could you provide a License for your ofxJSON?

Hi, I read this forum post : https://forum.openframeworks.cc/t/create-your-own-json-data-and-save-json-file/16560

And tried to reproduce the example with ofxJSON.

But when I use an ofxJsonElement as value for another OfxJsonElement, it compiles fine, but crash when the code is executed.

My code in ofApp.h :

ofxJSONElement list;
ofxJSONElement papa;

My code in ofApp.cpp::setup :

list["yolo"]["pit"] = 1;
list["yolo"]["put"] = "morteau";
list["yolo"]["pot"] = 1.36;
papa["lol"]=666;
list["yolo"]["pot"]["54"] = papa;
ofLog() << list ;

The error I got :

std::_Tree_comp_alloc<std::_Tmap_traits<Json::Value::CZString,Json::Value,std::lessJson::Value::CZString,std::allocator<std::pair<Json::Value::CZString
const ,Json::Value> >,0> >::_Myhead(...) returned 0x5C28F5C7.

I use of0.9.8 with vs2015.

I've been experiencing some strange issues with my JSON parsing.

So if a file I have is named:
example.1.json does not load.
example-1.json does not load.
example1.json loads fine.
Any ideas?

This may be an issue with ofBuffer.

Hi team, thanks for keeping this addon updated and easy to use.

Just wanted to flag that I've run into an issue where my JSON objects are ALWAYS sorted (alphabetically or by value) the moment I open the raw string with ofxJSONElement, while I need them to remain in the order in the raw string.

At the moment, I'm manually re-ordering them, but perhaps there's an easy way to stop this from happening?

Cheers!

Here's some example code:

ofxJSONElement json;
json.parse( "{ \"charlie\":4, \"alpha\":0.876, \"delta\":\"someString\", \"beta\":123 }" );

cout << json.getRawString();
// prints {"alpha":0.876,"beta":123,"charlie":4,"delta":"someString"}

I was looking at openRemote and it looks like it can only handle GET requests.

https://github.com/jefftimesten/ofxJSON/blob/master/src/ofxJSONElement.cpp#L70

I was wondering if its possible to use this for POSTs as well?

-cheers,
micah

do you have any sample for updating json value?
