Guide to fetching a string using Angular's http client?

I am facing an issue with calling a server that returns a csv file as text. I am using Angular's HttpClient and I need to prevent it from trying to cast the csv file to JSON. I tried setting the responseType to 'text' in the httpOptions, but it resulted in a TypeScript error that I had to ignore using @ts-ignore.

This is the code I am using:

const httpOptions = {
  headers: new HttpHeaders({
    Accept: "text/plain",
    "Content-Type": "application/json",
  }),
  responseType: "text",
};

return this.httpClient.post<string>(
  `/api/csv`,
  {
    id: "1111",
    // more data
  },

  httpOptions
);

The error message is too long for me to pinpoint the exact issue. I found this solution on Stack Overflow, but it seems to be outdated. Unfortunately, I am unable to identify the problem here.

This is the error I am getting:

 [Error message here]

Can anyone help me identify what I am missing?

Answer №1

After some investigation, I have come across a solution.

Instead of using 

this.httpClient.post<string>("/api/csv", {responseType: "text"})
, I realized that I need to use 
this.httpClient.post("/api/csv", {responseType: "text"})
. Therefore, the <string> is unnecessary.
