[英]Convert JSON to YAML. Parsing JSON to YAML
I'm working with configuration files so I need to convert JSON to YAML.我正在处理配置文件,所以我需要将 JSON 转换为 YAML。 For example I have this JSON file:例如我有这个 JSON 文件:
{
"foo": "bar",
"baz": [ "qux","quxx"],
"corge": null,
"grault": 1,
"garply": true,
"waldo": "false",
"fred": "undefined",
"emptyArray": [],
"emptyObject": {},
"emptyString": ""
}
The result should be YAML:结果应该是 YAML:
foo: "bar"
baz:
- "qux"
- "quxx"
corge: null
grault: 1
garply: true
waldo: "false"
fred: "undefined"
emptyArray: []
emptyObject: {}
emptyString: ""
Could you help me?你可以帮帮我吗?
You can convert JSON to YAML with two lines of code in Jackson :您可以使用Jackson 中的两行代码将 JSON 转换为 YAML:
import java.io.IOException;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.yaml.YAMLMapper;
public class Library {
public String asYaml(String jsonString) throws JsonProcessingException, IOException {
// parse JSON
JsonNode jsonNodeTree = new ObjectMapper().readTree(jsonString);
// save it as YAML
String jsonAsYaml = new YAMLMapper().writeValueAsString(jsonNodeTree);
return jsonAsYaml;
}
}
You will need to add dependencies to Jackson Core, DataBind and DataFormat YAML.您需要向 Jackson Core、DataBind 和 DataFormat YAML 添加依赖项。 Below is a snippet for Gradle:下面是 Gradle 的一个片段:
compile 'com.fasterxml.jackson.core:jackson-core:2.8.6'
compile 'com.fasterxml.jackson.core:jackson-databind:2.8.6'
compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:2.8.6'
Here's a one liner for a file, suitable for sticking in a bash script.这是一个文件的单行代码,适合粘贴在 bash 脚本中。 This should work on most default pythons on most systems:这应该适用于大多数系统上的大多数默认 python:
python -c 'import json; import yaml; print(yaml.dump(json.load(open("inputfile"))))'

I'd suggest you consider Data Transformer (disclaimer - I'm its developer).我建议您考虑使用Data Transformer (免责声明 - 我是它的开发人员)。 It converts between JSON, YML, and other formats.它可以在 JSON、YML 和其他格式之间进行转换。
You can get it from the Mac App Store or theMicrosoft Store .您可以从Mac App Store或Microsoft Store获取它。
function yaml_validate {
python -c 'import sys, yaml, json; yaml.safe_load(sys.stdin.read())'
}
function yaml2json {
python -c 'import sys, yaml, json; print(json.dumps(yaml.safe_load(sys.stdin.read())))'
}
function yaml2json_pretty {
python -c 'import sys, yaml, json; print(json.dumps(yaml.safe_load(sys.stdin.read()), indent=2, sort_keys=False))'
}
function json_validate {
python -c 'import sys, yaml, json; json.loads(sys.stdin.read())'
}
function json2yaml {
python -c 'import sys, yaml, json; print(yaml.dump(json.loads(sys.stdin.read())))'
}

If you need convert JSONobject to yaml (string).如果您需要将 JSONobject 转换为 yaml(字符串)。 you need.你需要。 Firstly get json string, then map, after that you can convert to yaml.首先获取json字符串,然后映射,然后您可以转换为yaml。 Here the code:这里的代码:
// this is your json object
JSONObject jsonobject = new JSONObject(map);
// get json string
String prettyJSONString = jsonobject.toString(4);
// mapping
Map<String,Object> map = (Map<String, Object>) yaml.load(prettyJSONString);
// convert to yaml string (yaml formatted string)
String output = yaml.dump(map2);
