NativeScript - nativescript-background-http无法正常工作

问题描述：

我正在尝试发布到我用C＃从用NativeScript创建的移动应用程序上制作的webapi。我正在使用nativescript-imagepicker和nativescript-background-http。但是error事件总是发射。NativeScript - nativescript-background-http无法正常工作

这是我的代码：我的两个进口：

import * as imagepicker from "nativescript-imagepicker"; 
import * as bghttp from "nativescript-background-http";

我这是怎么了图像的URI：

SelectImage(): void { 
     let context = imagepicker.create({ 
      mode: "single" 
     }); 

     context.authorize() 
       .then(() => { return context.present() }) 
       .then((selection) => { 
        selection.forEach((selected) => { 
         this.signupModel.CIPath = selected.fileUri; 
        }) 
       }).catch((e) => { 
        console.log(e); 
       }); 
    }

这就是我如何努力发布数据：

SignUp(): void { 
     let session = bghttp.session("image-upload"); 

     let request = { 
      url: "http://localhost:53286/api/Home/Signup", 
      method: "POST", 
      headers: { 
       "Content-Type": "application/octet-stream", 
       "File-Name": this.signupModel.CIPath 
      }, 
      description: "{ 'uploading': 'Uploading file...' }" 
     }; 

     let task: bghttp.Task; 

     let params = [{ 
      name: "ImageCI", mimeType: "image/jpeg", filename: this.signupModel.CIPath 
     }, { 
      name: "Rut", value: this.signupModel.Rut 
     }, { 
      name: "Name", value: this.signupModel.Name 
     }, { 
      name: "Address", value: this.signupModel.Address 
     }, { 
      name: "Commune", value: this.signupModel.Commune 
     }, { 
      name: "PhoneNumber", value: this.signupModel.PhoneNumber 
     }, { 
      name: "Email", value: this.signupModel.Email 
     }, { 
      name: "Password", value: this.signupModel.Password 
     }]; 

     task = session.multipartUpload(params, request); 

     task.on("error", (response: any) => { 
      console.log(JSON.stringify(response)); 
      alert({title: "Sistema 3 Esferas", message:"Error subiendo imagen...", okButtonText: "Cerrar"}); 
     }); 

     task.on("responded", (response: any) => { 
      console.log(JSON.stringify(response)); 
     }); 
    }

我该做什么错了？提前致谢。 :)

在模拟器上测试？如果是这样，请记住默认配置不能与'localhost'一起使用 - 请参阅此主题以了解详细信息https://*.com/a/39958955/4936697 –

错误响应是什么？ –

感谢尼克，您的评论。

是的，它的工作。我不得不改变这一行：

url: "http://localhost:53286/api/Home/Signup"

到：

url: "http://10.0.2.2:53286/api/Home/Signup"

这解决了这个问题。 :)
