离子在设备控制台上显示错误错误：advanced-http：无效的params对象，需要是带有字符串的对象错误：advanced-http：无效的params对象，必须是带有字符串的对象。

  private http: HTTP
   verify(){

      this.http.get('http://outreach.pk/api/sendsms.php/sendsms/url?id=rchiginsurance&pass=igi123456&mask=IGInsurance&lang=English&type=xml',
         {
  params: {
  to: this.mobile.value,
  msg: this.number1
  }
  },
   {});

  }

Answer 1

您需要使用set来设置请求的标头，如下所示：

this.http.setHeader('*', String("Content-Type"), String("application/json"));
this.http.setHeader('*', String("Accept"), String("application/json"));

，您需要设置序列化器

this.http.setDataSerializer('json');

Answer 2

由于标题为空，因此只需在标题对象中输入“ null”并设置序列化程序即可。例如：

this.http.setDataSerializer("json");
this.http.post(url, body, null).then(res => {....});

或

this.http.setDataSerializer("json");
this.http.post(url, body, {headers: {'Content-Type: application/json'}}).then(res => {....});

将其写在离子电容器2.4和ionic-native / http 5.29

上
