We\'ve got a .net WebAPI which looks for a filepath string in the body of a post request and returns the corresponding image. I\'m struggling to successfully pass a string t
You can get the path
from query
by removing [fromBody]
attribute
public HttpResponseMessage ImagesFromPaths(HttpRequestMessage request, string path)
and in post send path in post
request ${apiUrl}/${path}
:
return this.http.post(
`${apiUrl}/${path}`,
{ headers: new HttpHeaders({
'Content-Type': 'application/json',
}), responseType: 'blob',
})
I just tried another altrnative way by this options and directing posting String path Json to body of post method.
getImage(path: string) {
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
return new Promise((resolve, reject) => {
this.http.post('${apiUrl}',path, options)
.map((res) => res.json()).share()
.subscribe(res => {
resolve(res)
}, (err) => {
reject(err);
});
});
}
I would be happy if it works.Thanks
There is almost everything good with your code. Main issue is Content-Type
header. If you want to send string to .NET
REST API with [FromBody]
annotation and use application/json
header value you should add ""
to your path param for example "test_value"
:
return this.http.post(
`${apiUrl}`,
`\"${path}\"` ,
{ headers: new HttpHeaders({
'Content-Type': 'application/json',
}), responseType: 'blob',
})
You can also use x-www-form-urlencoded
header value. Then you must pass your param to request body in that way:
return this.http.post(
`${apiUrl}`,
`=${path}` ,
{ headers: new HttpHeaders({
'Content-Type': 'application/x-www-form-urlencoded',
}), responseType: 'blob',
})
