Although our document is json parsing (1), it can also be used for json parsing

提示：以下是本篇文章正文内容，下面案例可供参考

1. json file display

The content of the file we need to parse today is:

{
    
    
	"status": "ok",
	"results": [{
    
    
		"text": "\u96be\u53d7",
		"score": 0.9967435002326965,
		"position": [
			[267.0, 267.0],
			[412.0, 412.0],
			[412.0, 412.0],
			[267.0, 267.0]
		]
	}, {
    
    
		"text": "\u5ce8",
		"score": 0.7575550675392151,
		"position": [
			[62.0, 62.0],
			[142.0, 142.0],
			[142.0, 142.0],
			[62.0, 62.0]
		]
	}, {
    
    
		"text": "\u6211\u8fd8\u80fd\u8bf4\u4ec0\u516c",
		"score": 0.420401394367218,
		"position": [
			[475.0, 475.0],
			[662.0, 662.0],
			[662.0, 662.0],
			[475.0, 475.0]
		]
	}, {
    
    
		"text": "\u6ca1\u5fc5\u8981",
		"score": 0.9887173175811768,
		"position": [
			[52.0, 52.0],
			[160.0, 160.0],
			[160.0, 160.0],
			[52.0, 52.0]
		]
	}, {
    
    
		"text": "\u884c\u884c\u884c\u4f60\u8bf4\u4e86\u7b97",
		"score": 0.9628203511238098,
		"position": [
			[269.0, 269.0],
			[677.0, 677.0],
			[677.0, 677.0],
			[269.0, 269.0]
		]
	}, {
    
    
		"text": "\u5fc3\u5982\u6b7b\u7070",
		"score": 0.9149372577667236,
		"position": [
			[99.0, 99.0],
			[557.0, 557.0],
			[556.0, 556.0],
			[98.0, 98.0]
		]
	}, {
    
    
		"text": "690\u00d7624",
		"score": 0.8837266564369202,
		"position": [
			[616.0, 616.0],
			[683.0, 683.0],
			[683.0, 683.0],
			[616.0, 616.0]
		]
	}]
}

2. Use steps

1. Convert String to Json

Among them, our data is the string we need to convert.
responseJson is serialized for our files

        string responseString = data;
        JObject responseJson = JObject.Parse(responseString);

2. Extract text

Get the value of the "status" field

        string status = (string)responseJson["status"];

Get the value of the "results" field

JArray resultsArray = (JArray)responseJson["results"];
        List<JToken> results = resultsArray.ToList();
        

Get the value of each result object in the "results" list

 			JArray positionArray = (JArray)item["position"];
            List<Vector2> positionList = new List<Vector2>();
            foreach (JArray point in positionArray)
            {
    
    
                float x = (float)point[0];
                float y = (float)point[1];
                positionList.Add(new Vector2(x, y));
             

            }

3. Finished product code display

The code is as follows (example):

void JsonText()
    {
    
    

        string responseString = data;
        JObject responseJson = JObject.Parse(responseString);
        //要获取“status”字段的值
        string status = (string)responseJson["status"];
        //要获取“results”字段的值
        JArray resultsArray = (JArray)responseJson["results"];
        List<JToken> results = resultsArray.ToList();
        //“results”列表中获取每个结果对象的值
        foreach (var item in results)
        {
    
    
            Debug.Log("text: " + item["text"]);
            Debug.Log("score: " + item["score"]);
            //texts.text += "text: " + item["text"]+"\n";
            //texts.text += "score: " + item["score"]+"\n";
            JArray positionArray = (JArray)item["position"];
            List<Vector2> positionList = new List<Vector2>();
            foreach (JArray point in positionArray)
            {
    
    
                float x = (float)point[0];
                float y = (float)point[1];
                positionList.Add(new Vector2(x, y));
                Debug.Log("x:  " + x + "   " + "y:  " + y);
                //texts.text += "x:  " + x+"\n";
                //texts.text += "y:  " + y+"\n";

            }

        }

4. Effect

The code is as follows (example):
