Question

我正在使用Unity 5.5.2f1 pro和facebook的SDK v 7.9.4

我有一个脚本，登录后（在前一个场景中管理）向FB发送一个API请求，询问朋友，姓名和电子邮件，并将该信息作为POST发送到php网站。

代码：

 [Serializable]
 public struct FBData {
 public string first_name;
 public string email;
 public string friends;
 public string id;}

 public class UserManagement : MonoBehaviour {

 string urlSaveUserData="some php website";
 public Text testTxt;
 FBData parsedData;

 // Use this for initialization
 void Start () {
     //Check if it's the first time the user is opening the app. 
     if (UserInfo.FIRST_TIME) {
         //update text (only used for testing, should be removed in production.) 
         testTxt.text = "Your user id is: " + UserInfo.ID;
         //Perform FB.API call to get User Data.
         getUserData ();

         //Save in SQL table. (won't get here if line in getUserData() is active)
         StartCoroutine ("saveUserData");
     } else {
         //do something else.
     }

注意：由于这是针对iOS的，我必须在设备上进行测试，因此我在屏幕上使用文本来显示信息（将其视为严格执行的打印语句）。

问题：在FB.API的回调函数中，我在文本Gameobject（aka testTxt）中写入了自定义UserInfo clss中保存的响应中的解析信息。它显示正确，但代码卡在那里。它不会继续下一个功能。但是，如果我删除/评论该行并且不在文本字段中显示任何内容。代码确实继续POST函数，但API调用的信息没有传递，即我的自定义类为空（让我相信根本没有调用回调函数）。

public void getUserData(){

     string query = "me?fields=first_name,email,friends";
     FB.API (query, HttpMethod.GET, Apicallback, new Dictionary<string, string> ());

 }

 private void Apicallback(IGraphResult result){
     //Parse Graph response into a specific class created for this result. 
     parsedData = JsonUtility.FromJson<FBData>(result.RawResult);

     //Pass each field into UserInfo class. 
     UserInfo.EMAIL = parsedData.email;
     UserInfo.FRIENDS = parsedData.friends;
     UserInfo.NAME = parsedData.first_name;
     UserInfo.FACEBOOKID = parsedData.id;

             /*problem area, if I comment line below, then previous information is apparently not stored. If left as is then testTxt displays correct information but code gets stuck there.  */
     testTxt.text = "This is the info from USerInfoInside the APICallback: " + UserInfo.EMAIL + UserInfo.FRIENDS + UserInfo.FACEBOOKID;
 }

以下功能是将信息发送到php网站，用于说明目的：

代码：

public IEnumerator saveUserData() {
     //get user info (this information is EMPTY if line in getUserData() is commented. 
     parsedData.id = UserInfo.FACEBOOKID;
     parsedData.friends = UserInfo.FRIENDS;
     parsedData.first_name = UserInfo.NAME;
     parsedData.email = UserInfo.EMAIL;

     //translate data into json

     string JsonBodyData = JsonUtility.ToJson (parsedData);

     //Custom  web request (POST method doesnt seem to work very well, documentation example sends empty form)
     var w = new UnityWebRequest(urlSaveUserData, "POST");
     byte[] bodyRaw = new System.Text.UTF8Encoding().GetBytes(JsonBodyData);
     w.uploadHandler = (UploadHandler) new UploadHandlerRaw(bodyRaw);
     w.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer();
     w.SetRequestHeader("Content-Type", "application/json");

     yield return w.Send();
     //work with received data...}

我被困在这里任何帮助表示赞赏。谢谢！

在将字符串直接用于JSON或HTTP POST和GET方法时，请务必使用EscapeURL。缺乏这种处理往往会使事情变得棘手，特别是在iOS平台上。

从我所看到的，这段代码

string query =＆＃34; me？fields = first_name，email，friends＆＃34 ;;

应该将

转义为

string query = WWW.EscapeURL（＆＃34; me？fields = first_name，email，friends＆＃34;）;

所以字符如＆＃34;？＆＃34;不会被编码为URL符号。

我假设您不需要为您的说明性示例执行此操作，因为UnityWebRequest已在内部转义您的POST请求字符串，但我无法完全确认。
