Expected behavior It should be able to accept plain text from API response. HttpClient cannot set responseType: 'text' as Get options as described in the documentaion. If the contentType is "text/plain", the defaultHttpResponseTransform should return the data without trying to change it. HttpClient does not retrieve API that returns plain text. Project Setup Go through the link Creating Angular Project to create a new project. Go through the following steps for creating Angular project to download file from server using Angular. When the data block is empty it seems that Angular is ignoring the default 'application/json' and setting the Content-Type to 'plain/text'. Modifying methods return a cloned instance with the change. Install the required module for Angular 8: execute command npm install angular/httplatest in command line tool. An Interceptor needs to implement the HttpInterceptor interface which is about implementing the intercept method.Function defaultHttpResponseTransform(data, headers) " or "" for example, these will result in angular throwing an error. Angular - HttpHeaders API > angular/common > angular/common/http modeedit code HttpHeaders link class final Represents the header configuration options for an HTTP request. Angular - HTTP GET Request Examples Watch on Simple GET request with response type This sends an HTTP GET request to the npm api for a list of packages that belong to the angular scope, then assigns the total returned in the response to the local property totalAngularPackages.Let's take a quick look at how it works.įirst of all let's create an interceptor. To test Angular application, we need to run following command. Also, import the FormsModule You must also include it in the the imports array as shown below. When we create the project using CLI, it downloads and installs everything we need to test an Angular application. ng new httpGet Import HttpClientModule To make HTTP Get request, we need to make use of the HttpClientModule, which is part of the package angular/common/http. Otherwise, Angular will try to parse the plaintext response, even if the response MIME type is set to text/plain. The most exciting thing of the HttpClient is the introduction of Interceptors which allow middleware logic to be inserted in the pipeline. We will test Angular HttpClient.get method in our example. In order for Angularâs HttpClient to process plaintext responses and not result in an error, you need to set responseType: 'text' in the options (which is the second parameter to. Description TLDR: A boolean as body is seen as text/plain where is should be seen as appl. In this case you donât need to type the response as the reponseType already do the trick. bug report Affected Package The issue is caused by package angular/common/http Is this a regression No. However if you're still interested in the whole Response object you can observe for it: // HttpClient ('â¦', ) responseType?: 'arraybuffer' | 'blob' | 'json' | 'text'
