Einheit: POST-request mit WWW-Klasse mit JSON

Ich versuche, eine POST-Anforderung an restful-web-APIs in der Einheit.

Header wäre Content-Type: application/json

Beispiel der raw-Daten-Eingang ist, wo die Daten ist der Schlüssel-und json-string ist der Wert:

{  
   "data":{  
      "username":"name",
      "email":"[email protected]",
      "age_range":21,
      "gender":"male",
      "location":"california"
   }
}

Hier ist mein script:

private static readonly string POSTAddUserURL = "http://db.url.com/api/addUser";
public WWW POST()
{
    WWW www;
    Hashtable postHeader = new Hashtable();
    postHeader.Add("Content-Type", "application/json");
    WWWForm form = new WWWForm();
    form.AddField("data", jsonStr);
    www = new WWW(POSTAddUserURL, form);
    StartCoroutine(WaitForRequest(www));
    return www;
}

IEnumerator WaitForRequest(WWW data)
{
    yield return data; //Wait until the download is done
    if (data.error != null)
    {
        MainUI.ShowDebug("There was an error sending request: " + data.error);
    }
    else
    {
        MainUI.ShowDebug("WWW Request: " + data.text);
    }
}

Wie kann ich senden Sie den Antrag mit WWW Klasse mit form und header? Oder einfach nur im Allgemeinen, wie sende ich diese Art von post-Anforderung?

  • Verwenden Sie new WWW(url, form.Daten, postHeader);

    Wenn Sie hinzufügen möchten rohen json-Daten ist es besser, nur geben Sie ohne WWWForm

    public WWW POST()
{
    WWW www;
    Hashtable postHeader = new Hashtable();
    postHeader.Add("Content-Type", "application/json");

    //convert json string to byte
    var formData = System.Text.Encoding.UTF8.GetBytes(jsonStr);

    www = new WWW(POSTAddUserURL, formData, postHeader);
    StartCoroutine(WaitForRequest(www));
    return www;
}

    Ich getan habe, dies zu tun unten. Let ' s go : ==>

    using UnityEngine;

using UnityEngine.UI;

using System.Collections;

using System.Collections.Generic;

public class btnGetData : MonoBehaviour {

 void Start()
 {
     gameObject.GetComponent<Button>().onClick.AddListener(TaskOnClick);
 }
 IEnumerator WaitForWWW(WWW www)
 {
     yield return www;


     string txt = "";
     if (string.IsNullOrEmpty(www.error))
         txt = www.text;  //text of success
     else
         txt = www.error;  //error
     GameObject.Find("Txtdemo").GetComponent<Text>().text =  "++++++\n\n" + txt;
 }
 void TaskOnClick()
 {
     try
     {
         GameObject.Find("Txtdemo").GetComponent<Text>().text = "starting..";   
         string ourPostData = "{\"plan\":\"TESTA02\"";
         Dictionary<string,string> headers = new Dictionary<string, string>();
         headers.Add("Content-Type", "application/json");
         //byte[] b = System.Text.Encoding.UTF8.GetBytes();
         byte[] pData = System.Text.Encoding.ASCII.GetBytes(ourPostData.ToCharArray());
         ///POST by IIS hosting...
         WWW api = new WWW("http://192.168.1.120/si_aoi/api/total", pData, headers);
         ///GET by IIS hosting...
         ///WWW api = new WWW("http://192.168.1.120/si_aoi/api/total?dynamix={\"plan\":\"TESTA02\"");
         StartCoroutine(WaitForWWW(api));
     }
     catch (UnityException ex) { Debug.Log(ex.Message); }
 }
