Single value in ionic http post param-CodePudding

Hi I'm new to ionic/angular and I'm reading someone else code and came across the function below in the Service

 makePostRequest(100)
 
 public makePostRequest(param) {
   return this.http.post('/sample/api', param);
 }

Does this mean param is sent as json body or just a value, online documentation just shows json body as the argument not a single value. Can someone help me with this

Thanks in advance.

CodePudding user response：

The post body is sent as serialized parameters as explained here.

In the example you have provided, they are calling the makePostRequest() function and providing an argument of 100. When the makePostRequest() function runs, it takes that value from the argument and sets it as a parameter which is then used to populate the body in the POST request.

You can still send single values as you would multiple values with something similar to this:

sendData() {
   const params = {
      number: 100
   };
   return this.http.post('myurl.com', data);
}

Or for multiple:

sendData() {
   const params = {
      number: 100,
      fruit: 'banana'
   };
   return this.http.post('myurl.com', data);
}

You can of course pass multiple arguments if you have parameters set up to accept them:

sendData(body: { score: number, fruit: string }) {
   return this.http.post('myurl.com', body);
}
