Angular Native不将帖子正文发送到服务器

Question

我正在使用Angular Nativescript应用程序。我尝试在其中发布数据到服务器，但是当我使用本机脚本预览应用程序预览时，它总是将空白正文发送到服务器。 这是我的服务功能。

register(data) {
    console.log(this.regUrl)
    return this.http.post(this.regUrl, data, { headers: new HttpHeaders({ 'Content-Type': 'application/json' }) });
  }

这是我的开发依赖项：

"dependencies": {
    "@angular/animations": "~8.2.0",
    "@angular/common": "~8.2.0",
    "@angular/compiler": "~8.2.0",
    "@angular/core": "~8.2.0",
    "@angular/forms": "~8.2.0",
    "@angular/platform-browser": "~8.2.0",
    "@angular/platform-browser-dynamic": "~8.2.0",
    "@angular/router": "~8.2.0",
    "@nativescript/theme": "~2.2.1",
    "nativescript-angular": "~8.20.3",

Sqlite导致了此问题。但它以前工作正常。
