名称
dict_to_jsonT_dict_to_jsonDictToJsonDictToJsondict_to_json — 将字典转换为JSON（JavaScript Object Notation）字符串。
签名
描述
dict_to_jsondict_to_jsonDictToJsonDictToJsonDictToJsondict_to_json transforms the dictionary passed in
DictHandleDictHandleDictHandleDictHandledictHandledict_handle into a JSON string and returns that string
in JsonStringJsonStringJsonStringJsonStringjsonStringjson_string。
Several optional parameters can be set that control the creation of
the JSON strings.
Those parameters can be set via GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name
and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value and are described in the documentation of
write_dictwrite_dictWriteDictWriteDictWriteDictwrite_dict:

dict_to_jsondict_to_jsonDictToJsonDictToJsonDictToJsondict_to_json can transform several dictionaries at once.
For this, DictHandleDictHandleDictHandleDictHandledictHandledict_handle must contain a tuple of dictionaries.
The output JsonStringJsonStringJsonStringJsonStringjsonStringjson_string will then contain one string
per input dictionary.
执行信息
- 多线程类型：独立（即使使用独占算子也能并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。

示例（HDevelop）
dict_to_json (dict{foo: 'bar', bar: [0:2]}, [], [], JSONString)
结果
如果参数有效，算子 dict_to_jsondict_to_jsonDictToJsonDictToJsonDictToJsondict_to_json 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
