MRTK AzureSpatialAnchors 教程打包报错 Reference Rewriter found some errors while running with command &quo

Azure 空间定位点入门 - Mixed Reality | Microsoft Docs

按照教程，导入下面的包后，打包会报错

• MRTK.HoloLens2.Unity.Tutorials.Assets.AzureSpatialAnchors.2.4.0.unitypackage

这因为这个包中使用了"RestSharp.dll"引起的。

Build errors when attempting multiplayer · Issue #246 · MicrosoftDocs/mixed-reality (github.com)

在这个issue中官方说会更新这个包，用unity的api替换resetsharp。

按照这个思路，查了一下是在"Assets\MRTK.Tutorials.AzureSpatialAnchors\Scripts\AnchorModuleScript.cs"中引用了这个dll，实现了一个文件上传的功能。

把这部分自己用unitywebrequest实现一下就可以了。

直接修改这一部分代码：

 1     public void ShareAzureAnchorIdToNetwork()
 2     {
 3         Debug.Log("\nAnchorModuleScript.ShareAzureAnchorID()");
 4 
 5         string filename = "SharedAzureAnchorID." + publicSharingPin;
 6         string path = Application.persistentDataPath;
 7 
 8 #if WINDOWS_UWP
 9         StorageFolder storageFolder = ApplicationData.Current.LocalFolder;
10         path = storageFolder.Path + "/";           
11 #endif
12 
13         string filePath = Path.Combine(path, filename);
14         File.WriteAllText(filePath, currentAzureAnchorID);
15 
16         Debug.Log($"Current Azure anchor ID '{currentAzureAnchorID}' successfully saved to path '{filePath}'");
17 
18         //try
19         //{
20         //    var client = new RestClient("http://167.99.111.15:8090");
21 
22         //    Debug.Log($"Connecting to network client '{client}'... please wait...");
23 
24         //    var request = new RestRequest("/uploadFile.php", Method.POST);
25         //    request.AddHeader("Accept", "application/json");
26         //    request.AddHeader("Content-Type", "multipart/form-data");
27         //    request.AddFile("the_file", filePath);
28         //    request.AddParameter("replace_file", 1);  // Only needed if you want to upload a static file
29 
30         //    var httpResponse = client.Execute(request);
31 
32         //    Debug.Log("Uploading file... please wait...");
33 
34         //    string json = httpResponse.Content.ToString();
35         //}
36         //catch (Exception ex)
37         //{
38         //    Debug.Log(string.Format("Exception: {0}", ex.Message));
39         //    throw;
40         //}
41 
42         var form = new WWWFormHelper();
43         form.AddFile("the_file", filePath);
44         form.AddField("replace_file", 1);
45         var header = new Dictionary<string, string>();
46         header.Add("Accept", "application/json");
47         header.Add("Content-Type", "multipart/form-data");
48         UnityWebRequestHelper.Instance.Post("http://167.99.111.15:8090/uploadFile.php", form, str =>
49         {
50             Debug.Log("Uploading file... please wait...");
51 
52             string json = str;
53         }, header);
54 
55         Debug.Log($"Current Azure anchor ID '{currentAzureAnchorID}' shared successfully");

最后一步，删掉"Assets\MRTK.Tutorials.AzureSpatialAnchors\Plugins\RestSharp.dll"
