When I call the GetServiceProviderId() function in my code, I am making a GET request to an API and expecting the result as a string that can be split.
GetServiceProviderId() {
this.http.get(this.rooturl + 'info', { headers: this.reqHeader });
var data = "mitId: 18, ServiceProvider: 2" <- this is the result received from the API
var dataspilitted = data.split(" ");
return dataspilitted[3];
}
Official documentation explains the importance of specifying the responseType in request options.
FetchServiceProviderId() {
return this.http.get(this.baseurl + 'details', { headers: this.requestHeader, responseType:'text' })
.map(response => {
var splitData = response.split(" ");
return splitData[3];
});
}
Wow, is that a JSON response? Why go through the trouble of converting it to a string, splitting it, extracting the 3rd word, then converting it back to a number and hoping nothing changes?
You can simplify this by just:
this.http.get(this.rooturl + 'info', { headers: this.reqHeader })
.subscribe(result => console.log('The result is: ', result.ServiceProvider));
To extract the necessary information, it is crucial to first subscribe to the HTTP call and then analyze the data retrieved from the response based on its format.
GetServiceProviderId() {
this.http.get(this.rooturl + 'info', { headers: this.reqHeader }).subscribe(
(data) => {
// Use a custom function like "parse(data)" to convert the data into a readable string
// data = parse(data)
this.dataSplit = data.split(" ")[3];
}
);
}
In the code snippet above, the parse(data) function needs to be defined by you to handle the manipulation of the data if it does not come in string format directly from the HTTP response.
