RESTHeart Error When Trying To Load CSV Data

I try to load csv data by using:
given().
contentType("text/csv").
body("num,name,val\n1,dror,x\n2,amir,y").
when().
log ().
all ().
post("csv?db=restheart&coll=poi&id=0").
then().log().ifError()
I get status 400:
"message": "Content-Type request header must be 'text/csv'"
although the header seems right:
Content-Type=text/csv; charset=ISO-8859-1
full log following:

Any idea what is going wrong?
I checked the code of the CsvLoader service (that handles the request) and it checks Content-Type to be exactly text/csv, so I think the problem is with the additional charset substring ; charset=ISO-8859-1
Force the Content-Type header to be exactly just text-cvs.
I also fixed this bug (see commit 47fa0821). Fix will be included in upcoming v5.0 release.

Downloading data from REST API response but getting a response code of -1

REST API details from documentation:
GET /REST/sql_snapshot/2003-03-01.sql.gz HTTP/1.1
Host: some.api.net
Authorization: Basic qpow3i12o3
The response shown below omits the message body, which contains binary compressed SQL data.
HTTP/1.1 200 OK
Date: Wed, 05 Mar 2003 10:19:46 GMT
Server: Apache/1.3.22 (Unix) (Red-Hat/Linux)Content-Type: application/octet-stream
I'm getting a response code of -1 from below.
URL url = new URL("https://some.api.net/REST/sql_snapshot/2003-03-01.sql.gz");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type", "application/octet-stream");
connection.setDoOutput(true);
connection.connect();

Axios REST Preflight OPTIONS 400 status on IE/Edge

I have a problem with my requests using Edge/IE. I'm getting a code 400 code on
preflight OPTIONS.
I'm adding a 2 additional headers to all my requests in application with axios:
Authorization:
if ( token ) {
axios.defaults.headers.common[ 'Authorization' ] = 'Bearer ' + token;
} else {
delete axios.defaults.headers.common[ 'Authorization' ];
}
Accept-Language:
if ( lang ) {
axios.defaults.headers.common[ 'Accept-Language' ] = lang;
} else {
delete axios.defaults.headers.common[ 'Accept-Language' ];
}
Here's how my request headers works in Chrome:
Accept-Language: pl-PL
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJOZXcgUGFzdG9yYWwgQXBwIiwiYXVkIjoiTmV3IHBhc3RvcmFsIHVzZXIiLCJpYXQiOjE1MTM1OTEzODUsImV4cCI6MTUxMzU5ODU4NSwidWlkIjoxMSwidHlwZSI6NCwibGFuZ3VhZ2UiOjEsImRpc3BsYXlOYW1lIjoiVGVzdG8gUHJvYm9zemN6eiJ9.qyFHZuCHC9-NpNqjY7keY7j4LE5zu5JKxK9VyAFwH60
Request headers in Edge:

Content-Type: text/html; charset=UTF-8
Date: Mon, 18 Dec 2017 11:29:49 GMT
Server: Apache/2.4.25 (Ubuntu)
When I remove Accept-Language header the application start working in Edge, but problem still exists in IE.
The only messages from browser is code http error 400 and the console log of error is:
description: "Network Error"
message: "Network Error"
stack: "Error: Network Error at createError (http://localhost:8080/index_bundle.js:68811:3) at handleError (http://localhost:8080/index_bundle.js:68656:7)"
Rest of the headers is standard for axios. On the backend we're using Slimp PHP framework.
Any idea how to debug the problem, or similar problems using standard REST requestes with React + Axios? Or what should I check in first order?

Titanium multipart file upload with different content types?

So I am trying to post to a Salesforce.com REST api that is expecting the following sample request -
POST /services/data/v33.0/chatter/feed-elements HTTP/1.1
Authorization: OAuth 00DRR0000000N0g!...
User-Agent: Jakarta Commons-HttpClient/3.0.1
Host: instance_name
Content-Length: 845
Content-Type: multipart/form-data; boundary=a7V4kRcFA8E79pivMuV2tukQ85cmNKeoEgJgq
Accept: application/json
--a7V4kRcFA8E79pivMuV2tukQ85cmNKeoEgJgq
Content-Disposition: form-data; name="json"
Content-Type: application/json; charset=UTF-8
{
"body":{
"messageSegments":[
{
"type":"Text",
"text":"Please accept this receipt."
}
]
},
"capabilities":{
"content":{
"description":"Receipt for expenses",
"title":"receipt.pdf"
}
},
"feedElementType":"FeedItem",
"subjectId":"005RR000000DmOb"
}
--a7V4kRcFA8E79pivMuV2tukQ85cmNKeoEgJgq
Content-Disposition: form-data; name="feedElementFileUpload"; filename="receipt.pdf"
Content-Type: application/octet-stream; charset=ISO-8859-1
...contents of receipt.pdf...
--a7V4kRcFA8E79pivMuV2tukQ85cmNKeoEgJgq--
As you can see, the two parts of the request is expecting different content types.
In Titanium, I have the following code -
xhr.open("POST", postUri);
xhr.setRequestHeader("Authorization", authHeader);
xhr.setRequestHeader('enctype', 'multipart/form-data');
var data2send = {
json: jsonObj,
feedElementFileUpload: imageBlob
};
xhr.send(data2send);
According to the Appcelerator documentation and a couple of online threads, the httpclient should be able to set each part automatically, however, Salesforce API still gives an error message of:
[{"errorCode":"MISSING_ARGUMENT","message":"Missing required 'subjectId' parameter."}]
I can confirm that subjectId is in the jsonObj and its content is correct. It seems that the json part is not recognised as JSON by Salesforce correctly. How can I set the content-type correctly? Many thanks.
Updates - I used the Wireshark to capture the request text. Apparently the httpclient did not set up the content-type for the json part that Salsforce API is expecting. Any idea how to set it?

Passing parameters to WCF restful service with POST method

how can I use Fiddler to pass 2 parameters to a method with a signature like this :
[WebInvoke(UriTemplate = "Login", Method = "POST", ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
bool Login(string login, string password);
Any suggestion to change something in the method is welcome, but I have always to pass 2 string parameters.
It is much easier to the services with WCFTestClient. Anyway, Fiddler has composer functionality which can be used to test any http calls.
Request Headers should look like below. Just change SOAPAction accordingly.
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://tempuri.org/IService/Login"
Host: localhost:2045
Content-Length: 179
Expect: 100-continue
Accept-Encoding: gzip, deflate
Proxy-Connection: Keep-Alive
And request body:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><Login xmlns="http://tempuri.org/"><login>sdf</login><password>sdf</password></Login></s:Body></s:Envelope>
