HttpMediaTypeNotAcceptableException / HttpMediaTypeNotAcceptableException: An acceptable view could not be found
I have an API that a client is trying to connect to. However, it throws an error:
2015 09 22 04:21:44.297 [org.springframework.web.servlet.mvc.method.annotation.HttpEntityMethodProcessor] Could not parse Accept header: Invalid token character ',' in token "json,application/x-www-form-urlencoded"

Controller:
@RequestMapping(value = {"order/add"}, method = RequestMethod.POST, produces="application/json; charset=utf-8")
@ResponseBody
public ResponseEntity<String> getNewOrderApi(HttpServletRequest request,
HttpServletResponse response) throws Exception {
.....
return JsonUtils.createJson(jsonObj);
}
They use jQuery to query my API:
$.ajax({
url: "https://api.mywebsite.com/apiv1/order/add",
type: 'POST',
beforeSend: function(xhr) {
xhr.setRequestHeader("Content-Type","application/json;charset=utf-8");
},
data : JSON.stringify(data),
dataType: 'json',
success: function(data) {
if (data.success == true){
console.log(data);
}else{
console.log("error: " + data.error_description);
}
}
});
The problem is in the "Content Type" request header:
Accept:application/json, text/javascript, */*
Accept-Encoding:gzip, deflate
Accept-Language:zh,zh-TW;q=0.8,en-US;q=0.6,en;q=0.4
Connection:keep-alive
Content-Length:561
Content-Type:application/x-www-form-urlencoded, application/json;charset=UTF-8
We don't know where the "app / x-www-form-urlencoded" ("," creates a problem because it should be ";") comes from. What can I do on my side? What can be done on their side?

I also faced the same problem.
I tried to use Android API using Volley.
There are 2 different types of content. One is the request header Content-Type
and the other is Body Content-Type
. When you initiate a request to POST
or PUT
from volleyball, volleyball request header and check the body Content-Type. If no Content-Type body is specified, the salvo will be added by itself. Volleyball combines both Content-Type and our server was only able to accept one Content-Type. But since volleyball combines Content-Type for header and body, it becomes "application / json, application / x-www-form-urlencoded; charset = utf-8".
Here " application/x-www-form-urlencoded
" is the content type for the request body. So, to solve this problem, you can override the method getBodyContentType()
and return null.
@Override
public String getBodyContentType() {
//return super.getBodyContentType();
return null;
}
Do not use return ""
. Usage return ""
also throws an exception.

Hope this helps.
