i'm currently trying to add a field into the Header of my Cypher request to tell the load-balancer wether it's a write or read request so it directs the query on Master or Slave Neo4j instance.
HttpClientWrapper clientWrapper = new HttpClientWrapper(ConfigurationManager.AppSettings["Neo4jUserName"], ConfigurationManager.AppSettings["Neo4jPassword"]);
Uri uri = new Uri(ConfigurationManager.AppSettings["Neo4jClient"]);
GraphClient client = new GraphClient(uri, clientWrapper);
client.JsonConverters.Add(new CoordinateConverter());
client.Connect();
...
NameValueCollection collection = new NameValueCollection();
collection.Add("X:Write", "1");
...
client.Cypher.CustomHeader(collection)...
But when executing the query, i'm getting Exception such as:
System.FormatException: "The header name format is invalid."
My question is, do the .CustomHeader(collection) override the standard Header instead of only adding the field X:Write ?
I'm struggling to find documentation on CustomHeader and how it's supposed to work.
Thanks in advance for reading me.
EDIT: Here is some code examples i found and should work: https://github.com/Readify/Neo4jClient/pull/149/files
The error was that i couldn't use ':' in the headername, changing the name to "IsWrite" solved the problem.

I am trying to POST files containing arbitrary binary data to a WebAPI 2 controller as multipart/form-data.
When trying to read the files using the following:
var provider = new MultipartFormDataStreamProvider(uploadDirectoryPath);
await Request.Content.ReadAsMultipartAsync(provider);
I get:
System.InvalidOperationException: The character set provided in ContentType is invalid.
Cannot read content as string using an invalid character set.
---> System.ArgumentException: '"utf-8"' is not a supported encoding name.
For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.
Parameter name: name
I understand that the problem is the quotes around utf-8 and it is this bug in HttpContent.ReadAsStringAsync() used internally as explained here.
The request is being sent from a Unity3D app and I am unable to change the charset in the request body.
Here is the code I am using in the Unity3D script to create the POST request.
WWW chunkFile = new WWW("file:///" + Path.Combine(tempZipFolderPath, chunkFilenames[j]));
yield return chunkFile;
if (chunkFile.error != null)
throw new Exception(string.Format("{0} error opening file {1}", chunkFile.error, chunkFilenames[j]));
//BUGFIX: Not using IMultipartFormSection because of https://fogbugz.unity3d.com/default.asp?826626_htlchp13nh8th2to
var form = new WWWForm();
form.AddField("chunkNumber", chunkNumber);
form.AddField("totalChunks", totalChunks);
form.AddField("identifier", tempZipFileName);
form.AddBinaryData("filename", chunkFile.bytes, chunkFilenames[j]);
var scanUploadPostRequest = UnityWebRequest.Post(WebApiScanUploadUrl, form);
yield return scanUploadPostRequest.Send();
//BUGBUG: charset UTF-8 wrapped in quotes causes error
Is there a workaround to this?
I am using a doc data payments gateway service and when I try to give it a request to create an order it throws the following exception:
XmlSerializer attribute
System.Xml.Serialization.XmlAttributeAttribute is not valid in
version. Only XmlElement, XmlArray, XmlArrayItem, XmlAnyAttribute and
XmlAnyElement attributes are supported when IsWrapped is true.
I don't think it is an exception that has anything to do with the service. What am I doing wrong on my side of implementation. Can anyone help me with that?
EDIT
I have used DocDataPayments gateway and used the wsdl refrence they give to make the call.
The create call I am making is as follows:-
PaymentServiceSOAPClient client = new PaymentServiceSOAPClient();
createSuccess success = new createSuccess();
client.create(merchant, strMTID, paymentPreferences, menuPreferences, shopper, totalGrossAmount, billTo, "description", "Thanks for your purchase", true, new paymentRequest(), new invoice(), new technicalIntegrationInfo(), Convert.ToDecimal(0.9), out success);
I think, you are using wcf default serializer to make proxy classes.you can try with DataContract serializer instead default serializer.
I'm trying to delete entries in my lightswitch database, from a external app.
I'm using restsharp, and the code looks like the following:
var request = new RestRequest("/FilesSet/{Id}", Method.DELETE);
request.AddParameter("Id", 8);
var resp = client.Execute(request);
Here is the full error message:
The request URI is not valid. Since the segment 'FilesSet' refers to a collection, this
must be the last segment in the request URI. All intermediate segments must refer to a
single resource.
It seems like you're trying to locate an entity and delete it. In the OData URL convention, the canonical URL for accessing an entity in a collection is as follows:
~/FilesSet({Id})
Thus, you need to modify your code as follows:
var request = new RestRequest("/FilesSet({Id})", Method.DELETE);
request.AddParameter("Id", 8);
var resp = client.Execute(request);
Reference: 4.3.1 Canonical URL
I've had success creating objects with POST and Content-Type application/xml
I've also had success querying using Content-Type application/x-www-form-urlencoded with a blank request body which returns all of the object type depending on which URI I specify.
I can also get the same to work with something like PageNum=1&ResultsPerPage=1 in the request body and I have figured out how to incorporate that into the signature so I get a valid response.
However no matter how I format it, I cannot get anything other than a 401 response when I try to use a filter (something basic like Filter=FAMILYNAME :EQUALS: Doe). I've read over the OAuth Core 1.0 Revision A specifications on how all parameter names and values are escaped using the [RFC3986] percent-encoding. However I feel like I'm missing a step or formatting incorrectly. I've seen inconsistent information in my searching through Intuit's forums on what exactly is the proper format.
Any help on this would be greatly appreciated. I've been struggling with this for a good week now.
The response I get when trying to use a filter is:
HTTP Status 401 - message=Exception authenticating OAuth; errorCode=003200; statusCode=401
----Update----
I'm am seeing the same error when I try to use filters with the New IPP Developer Tools - IPP API Explorer. I'm using the IDS V2 QBO API Explorer. I'm able to use that tool to do a retrieve all Post and the response shows all of my customers, but when I try to use a filter I get :
Server Error
401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
Any Ideas? If I'm getting the same error from the API Explorer tool, it makes me think the problem is something else entirely.
----Final Update----
I have finally had success with filters and I believe I have figure out what my problem was. I was always suspicious that I was able to get queries with pagination like "PageNum=1&ResultsPerPage=1" to work, but could not get something like "Filter=FAMILYNAME :EQUALS: Doe". I suspected there problem was with the white space in the filter format. What threw me off tracking this down earlier was that I could not get the filters to work in the IDS V2 QBO API Explorer. That made me suspect there was something else going on. I decided to ignore the API Explorer all together and focus on why I could get it to work the one way but no the other.
I believe my problem came down to improper encoding of the Filter's value in the signature. That explains the 401 invalid signature errors I was getting.
"Filter=Name :EQUALS: Doe" becomes "Filter=Name%20%3AEQUALS%20%3ADoe" after normalization.
Percent-Encoding that should give "Filter%3DName%2520%253AEQUALS%2520%253ADoe".
In essence you have to "double" encode the blank space and the colons, but not the equal sign. I tried many permutations of doing the encoding, but believe my mistake was that I was either not "double" encoding, or when I was double encoding I was including the '=' sign. Either way breaks your signature. Thanks for everyone's input.
I believe my problem came down to improper encoding of the Filter's value in the signature. That explains the 401 invalid signature errors I was getting.
I used an online tool to take me through the steps in properly signing an Oauth request. While going through those steps I realized my problem was with the steps where you normalize the request parameters and then percent-encode them. I was including the '=' of the filter in the normalization step, which breaks your signature. The tool I used can be found at:

Thanks for everyone's input.
Do you get a 401 with the same request in the API Explorer?
http://ippblog.intuit.com/blog/2013/01/new-ipp-developer-tool-api-explorer.html
Also, are you using the static base URL or retrieving it at runtime?
https://ipp.developer.intuit.com/0010_Intuit_Partner_Platform/0050_Data_Services/0400_QuickBooks_Online/0100_Calling_Data_Services/0010_Getting_the_Base_URL
If you are using the static base URL, try switching to the runtime base URL to see if you still get the error.
peterl answered one of my questions on here that may also answer yours. I had been trying to put the Filters in the body when they should have gone into the header. Here was peterl's code sample for getting all unpaid invoices (open balance greater than 0.00) for a particular customer.

I am trying to do a simple Salesforce-Asana integration. I have many functions working, but I am having trouble with adding a tag to a workspace. Since I can't find documentation on the addTag method, I'm sort of guessing at what is required.
If I post the following JSON to https://app.asana.com/api/1.0/workspaces/WORKSPACEID/tasks:
{"data":{"name":"MyTagName","notes":"Test Notes"}}
The tag gets created in Asana, but with blank notes and name fields. If I try to get a bit more fancy and post:
{"data":{"name":"MyTagName","notes":"Test Notes","followers":[{"id":"MY_USER_ID"}]}}
I receive:
{"errors":[{"message":"Invalid field: {\"data\":{\"name\":\"MyTagName\",\"notes\":\"Test Notes\",\"followers\":[{\"id\":\"MY_USER_ID\"}]}}"}]}
I'm thinking the backslashes may mean that my request is being modified by the post, though debug output shows a properly formatted json string before the post.
Sample Code:
JSONGenerator jsongen = JSON.createGenerator(false);
jsongen.writeStartObject();
jsongen.writeFieldName('data');
jsongen.writeStartObject();
jsongen.writeStringField('name', 'MyTagName');
jsongen.writeStringField('notes', 'Test Notes');
jsongen.writeFieldName('followers');
jsongen.writeStartArray();
jsongen.writeStartObject();
jsongen.writeStringField('id', 'MY_USER_ID');
jsongen.writeEndObject();
jsongen.writeEndArray();
jsongen.writeEndObject();
jsongen.writeEndObject();
String requestbody = jsongen.getAsString();
HttpRequest req = new HttpRequest();
req.setEndpoint('https://app.asana.com/api/1.0/workspaces/WORKSPACEID/tags');
req.setMethod('POST');
//===Auth header created here - working fine===
req.setBody(requestbody);
Http http = new Http();
HTTPResponse res = http.send(req);
return res.getBody();
Any help appreciated. I am inexperienced using JSON as well as the Asana API.
The problem was that I was posting to the wrong endpoint. Instead of workspaces/workspaceid/tags, I should have been using /tags and including workspaceid in the body of the request.
Aha, so you can add tags and even set followers despite the API not mentioning that you can or claiming that followers are read-only.
So to sum up for anyone else interested: POSTing to the endpoint https://app.asana.com/api/1.0/tags you can create a tag like this:
{ "data" : { "workspace": 1234567, "name" : "newtagname", "followers": [45678, 6789] } }
where 1234567 is your workspace ID and 45678 and 6789 are your new followers.
Since you posted this question, Asana's API and developer has introduced Tags. You documentation lays out the answer to your question pretty clearly:
https://asana.com/developers/api-reference/tags
I'm a bit confused by your question. Your ask "how to add a tag" but the first half of your question talks about adding a task. The problem with what you describe there is that you are trying to set a task's followers but the followers field is currently read-only according to Asana's API documentation. That is why you are getting an error. You can not set followers with the API right now.
The second part of your question - with the sample code - does look like you are trying to add a tag. However, right now the Asana API does not support this (at least according to the API documentation). You can update an existing tag but you can't add one.
So, to sum up: at this time the API does not allow you to add followers to a task or to create new tags.
