How to Concatenate String and Numbers to Make a Json Object

how to combine integer and string into JSON object android

Try this way:

 final JSONObject obj = new JSONObject();
     obj.put("add_device",String or integer);
     obj.put("group_description",String or integer);
     obj.put("add_group",String or integer);
     System.out.println("Formed String is-->"+obj);

JSON: key value concatenation in javascript

finalStr = ''
Object.keys(obj).forEach(function(key) {
  if (obj[key].name === 'mountpoints') { // only get sizes for mountpoints
    var value = obj[key].value;
    Object.keys(value).forEach(function(name) { // add all sizes to string
      finalStr += '"' + name + '" - ' + value[name].size + ';';
    }); //update
  }
}); //update

if (finalStr.length > 0) { // at least one entry was added
  finalStr.slice(0, -1);
}

Concat two json strings in c#

This might be a bit overkill, but you'll be guaranteed to get a meaningful error in the case of malformed data, or you'll get valid JSON.

var arrayOfObjects = JsonConvert.SerializeObject(
    new[] { JsonConvert.DeserializeObject(json1), JsonConvert.DeserializeObject(json2) }
)

We deserialize each json object into object (so we don't need to care about the structure), wrap it in an object[], and serialize it back into JSON. Unless you're parsing a huge amount of objects, this should be sufficiently performant.

MySQL 5.7 Concatenate values of JSON string into one string

You can use a catalog table such as information_schema.tables in order to generate rows to iterate by the length of the array, and then aggregate all members by using GROUP_CONCAT() such as

SELECT GROUP_CONCAT(
                    JSON_UNQUOTE(
                       JSON_EXTRACT(content,
                                    CONCAT('$.blocks[', i - 1, '].score'))
                                   ) 
                       SEPARATOR '') AS scores
  FROM (SELECT JSON_LENGTH(JSON_EXTRACT(content, '$.blocks[*].score')) AS len,
               @i := @i + 1 AS i,
               content
          FROM tab
          JOIN information_schema.tables
          JOIN (SELECT @i := 0) AS i) AS t
 WHERE i <= len;

|  AAB   |

Python string concatenation for JSON payload

You can properly form your json this way:

import json
username = "jose"
email = "some_email"
password = "1234"

url = "some_url"

payload = json.dumps({"username": username, "email":email, "password":password}, indent=4)
headers = { 'Content-Type': 'application/json'}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text.encode('utf8'))
