Question

我正在创建从API检索/写入数据并为Android应用程序使用http native的应用程序。获取方法现在可以了。但是，当我使用邮寄和修补程序保存数据时，该方法尚无法使用。

能否请您指导我如何使用POST保存数据？这是我的代码，如下所示：

在service.ts中，

 updateProfile(userProfile) {
    console.log("UpdatePro_"+JSON.stringify(userProfile));
    return this.http.patch(this.mcs.mobileBackend.getCustomCodeUrl(mcsConfig.environment + '_api_care/my/profile'), userProfile, this.getMcsHeadersString());
  }

getMcsHeadersString() {
    var cheaders = {};
    for (let key in this.mcs.mobileBackend.getHttpHeaders()) {
      cheaders[key]= this.mcs.mobileBackend.getHttpHeaders()[key];
    }
    //console.log("STring_HeaderKey_"+cheaders['_keys']+"HeaderValue_"+cheaders['_values']);
    delete cheaders['_keys'];
    delete cheaders['_values'];
    return cheaders;
  }

在profileedit.ts

save() {

    this.mcsService.updateProfile(this.userProfile).then((res) => {

      console.log("testUp"+this.userProfile);
      this.router.navigate(['menu/profile']);
    }, (err) => {
      console.log("Invalid_"+err.error);
      this.presentAlert(err.error);
    }
    );
  }

错误消息显示如下：

{"message":"Custom Code Problem in callback: RangeError: Invalid status code: 0"}

答案是我需要解析JSON obj，例如this.userProfile.user_name = JSON.parse（mcsService.userProfile）.user_name;

错误：自定义代码回调中的问题：RangeError：无效的状态代码：0
