I have a class that models exactly the entity I have in the database. I have a stored procedure that takes in parameters for a new row and returns all the settings in the table which in turn populates my repository. I am able to see the results of GET, PUT and DELETE in the List of type Setting that is in memory. I am noticing first that even when I close Visual Studio and reopen and run the project, sometimes, the List is still in the state it was before. It is not repopulating from the database so I'm not sure why that is first of all... Secondly, I can't seem to get POST to work from Fiddler unlike the other HTTP verbs. I DO see the values from Fiddler show up in the code below but I get the error: Invalid URI: The format of the URI could not be determined. I get the same error if I pass an ID or not.
Here is what I put into Fiddler:
POST localhost:54852/api/settings
Request Headers
User-Agent: Fiddler
Content-type: application/x-www-form-urlencoded
Host: localhost:54852
Content-Length: 149
Request Body
ID=0&Category=Dried%20Goods&Sub_Category=Other&UnitSize=99&UnitOfMeasureID=999&Facings=true&Quantity=true&EverydayPrice=999.99&PromotionPrice=111.11
PostSetting function within my SettingsController
public HttpResponseMessage PostSetting(Setting item)
{
item = repository.Add(item);
var response = new HttpResponseMessage<Setting>(item) { StatusCode = HttpStatusCode.Created };
string uri = Url.Route("DefaultApi", new { id = item.ID });
response.Headers.Location = new Uri(uri);
return response;
}
Should I create a new procedure that gets the MAXID from the database and use that as the NEW ID in the line above where a new ID is created?
You need to create a JSON representation of the Setting class or item that you are wanting to test with use Fiddler (now a Telerik product) and use the Composer tab.
Next you will want to perform a POST to the following URL:
http://[your base url]/api/settings
and pass the JSON formatted setting class.
You can see an example of this here: ASP.NET Web API - Scott Hanselman
Here is a short video showing how to achieve it easily

I'm doing a program that will help me to make monthly reports and I stuck at uploading photos which I need for one kind of the reports. For some reason, it doesn't get an array in the controller.
I use Springboot RestController at the backend and Vue with BootstrapVue and vue-resource on the other side.
index.html (BootstrapVue):
<b-form-file
v-model="photos"
accept="image/*"
multiple
placeholder="..."
></b-form-file>
<b-button #click="uploadPhotos">Upload</b-button>
inside vuemain.js:
data: {
photos: null,
},
methods: {
uploadPhotos(){
var formData = new FormData();
formData.append("photos", this.photos);
this.$http.post('reports/photo', formData).then(result => {
...
})
}, ...
inside Controller:
#PostMapping("/photo")
public void addPhoto(#RequestParam("photos") MultipartFile[] photo) {
System.out.println(photo.length); // shows 0
}
what I see inside Params at browser:
XHRPOSThttp://localhost:8080/reports-maker/reports/photo
[HTTP/1.1 500 326ms]
Request payload
-----------------------------4469196632041005505545240657
Content-Disposition: form-data; name="photos"
[object File],[object File],[object File],[object File]
-----------------------------4469196632041005505545240657--
So for some reason at this point #RequestParam("photos") MultipartFile[] photo it's empty array. But if I change it to just one photo like this: #RequestParam("photos") MultipartFile photo and send one from js: formData.append("photos", this.photos[0]); everything works nicely and photo gets uploaded to the server.
It's my first experience with Vue and to be honest I don't want to go deep into JS learning, so probably there is some silly mistake somewhere. Any way I can use a loop in JS method to upload them one by one, but that would be so ugly. I hope there is a better way to do it (without any additional JS libraries of course).
If you use axios then you should add header
var headers = {
'Content-Type': 'multipart/form-data',
};
axios.post(
'reports/photo',
formData,
{
headers: headers,
}
)
...
to be able send files to the server.
I agree, sending files in separate requests one by one is very "ugly", but I also don't like the idea of not using the mapping resources of Spring Boot, having to send all files with different names (seems disorganized) and having to work with MultipartHttpServletRequest, but there is a simple solution for this: Ian's answer to this question (not realy related to Vue.js, but useful) worked for me:
In order for Spring to map items in a request to a list, you need to provide the same name (in the FormData.append calls) for each item when appending to the form data. This allows Spring to effectively see the request as name=value1&name=value2&name=value3 (but obviously in the form of form data). When Spring sees the same key ("name") multiple times, it can map the values into a collection.
In your .vue file, append the photos with the same name:
for (let i = 0; i < this.photos.length; i++) {
formData.append("photos", this.photos[i]);
}
And in your Controller:
#PostMapping("/photo")
public void addPhoto(#RequestParam("photos") MultipartFile[] photo) {
System.out.println(photo.length); // Should be greater than 0 now
}
Note:
I used Vue Axios to consume my API and manually added the Content-Type: multipart/form-data header. Make sure its in your request header list.
I found an acceptable solution here https://stackoverflow.com/a/33921749/11508625 Rossi Robinsion's code works nicely. At least it looks better than sending files in separate requests one by one.
The answer is based on using getFileNames() which helps to iterate on files inside a request even if they are not in the array.
I have created Spring boot (2.1.4.RELEASE) REST endpoint to GET some data from the server. When I call this endpoint from the browser, I see the JSON in the browser window but I notice that the the spinner in fav icon is going on for 60 seconds. When i look at the network tab, I never see the response section for the request. After 60 seconds, it says that it failed. When I walk through the code in debugger, I see that data is being returned from the controller and when I 'play' the rest of the stack everything completes (thread that is being assigned to serve the request) I am kind of puzzled what's causing this behavior.
#GetMapping(path="/recipes")
public ResponseEntity<Collection<HpManifest>> getRecipes() {
ResponseEntity<Collection<HpManifest>> response = hpService.getRecipes();
return response;
}
public ResponseEntity<Collection<HpManifest>> getRecipes() {
logger.info("Retrieving recipes from");
UriComponentsBuilder builder =
UriComponentsBuilder.fromHttpUrl(endpointManifests)
.queryParam("type", HpManifestType.RECIPE.getType());
logger.info("REST endpoint: " + builder.toUriString());
ResponseEntity<Collection<HpManifest>> recipes = restTemplate.exchange(
builder.toUriString(),
HttpMethod.GET, null, new ParameterizedTypeReference<Collection<HpManifest>>() {});
logger.info("recipes are:");
recipes.getBody().forEach(r -> logger.info(r.toString()));
return recipes;
}
I ran into a similar issue just the other day. In my case it turned out to be that recipes (returned from the restTemplate.exchange method) contained a Transfer-Encoding: chunked in the headers and then when you return recipes, your spring framework is probably also including a Content-Length header. The combination of these two headers in a response to a browser can cause issues because the browser thinks it's getting chunked data back, but in reality it is not. I suggest making a new ResponseEntity from your recipes variable along the lines of:
return ResponseEntity.status(recipes.getStatusCode()).body(response.getBody());
Alternatively you could maybe force your spring framework to return chunked data, but I think that is not the right way to go.
Question: How do I create a subpanel record through the SugarCRM rest api endpoint for accounts?
Steps taken so far:
I've added a new package called, "transactionHistory" with a module named, "InvoiceHistory" using the SugarCRM studio.
I added a One to Many relationship to the Accounts module using studio.
I'm using NetSuite to push new invoices to the new module's record via the subpanel "create" option. Here's the code I'm using:
function createSugarTransaction(transaction, token) {
var url = 'https://crm.techsoft3d.com/rest/v10/Accounts/' + transaction.customer;
var headers = {
"Content-Type": "application/json",
"OAuth-Token": token
};
var now = (new Date()).toISOString();
var body = {transactionHistory_InvoiceHistory:
{
create: [{
name: transaction.docId,
transaction_date_c: transaction.date,
invoice_status_c: transaction.status,
due_date_c: transaction.duedate,
total_amount_c: transaction.total,
amount_due_c: transaction.remaining,
start_date_c: transaction.startdate,
end_date_c: transaction.enddate
}]
}
};
var response = nlapiRequestURL(url, JSON.stringify(body), headers, 'PUT');
return response;
}
The transaction object has been validated and the json object within the create: [] array has matching sugar fields (key) with the corresponding transaction object values.
When making the API call to sugar I'm successfully authenticated and have access to the custom module and accounts - so no problem there. However, when the call is returned to response it's showing the following error:
{"error":"no_method","error_message":"Could not find a route with 1 elements"}
I'm unsure of what else is needed in order for the record to be created. According to sugar's help documentation and developer community this should work. I'm using the basic information provided by sugarcrm support portal:
http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.6/API/Web_Services/Examples/v10/module_POST/
According to other blog posts within the developer community, it should be as simple as adding the subpanel name, followed by an array of fields under the "create" object... similar to this:
var requestBody = { package_module:create[{name:value}]};
My initial thinking of what's wrong is:
1. my package_module name isn't correct, but I'm unable to find it anywhere within the applicaiton or help documentation.
2. the request body isn't formatted properly, even though it's structure was copied from this article https://developer.sugarcrm.com/2014/02/28/sugarcrm-cookbook2/
Any help would be appreciated.
try the createRelatedRecord api endpoint
type {sugarurl}/rest/v10/help to see a list of endpoints to look through, most of which have documentation and examples
https://crm.techsoft3d.com/rest/v10/help
your API url should have the name of the link (relationship) you want, in addition to the values in the POST payload
https://crm.techsoft3d.com/rest/v10/Accounts/{transaction.customer}/link/accounts_transactionhistory (or whatever your link's name is)
per the documentation for this endpoint, you just specify the field values in the payload
{
"first_name":"Bill",
"last_name":"Edwards"
}
I created a Web API 2 project and configured an OData4 controller following the steps here: Web API 2 Odata 4 Tutorial
However whenever I try and do a simple POST(with a JSON body to create an entity) using Postman I get the following error back:
The requested resource does not support http method 'POST'.
The POST action in the controller looks like this:
public async Task<IHttpActionResult> Post(Product product)
{
if(!ModelState.IsValid)
{
return BadRequest(ModelState);
}
db.Products.Add(product);
await db.SaveChangesAsync();
return Created(product);
}
The JSON I am posting in the request body is as follows:
{
"Id":"lewisblack",
"Name":"Lewis",
"Price":"Black",
"Category":"Category 1"
}
And I included the following headers in the request as well:
OData-Version: 4.0
OData-MaxVersion: 4.0
Content-Type: application/json
Am I missing something here?
UPDATE: Figured out the issue. I was using an incorrect URI.
Not much information to go on:
I suspect you don't have a PostMethod on the related controller.
Otherwhise, some other things to think about:
OData is case sensitive
You are missing a property that is required
a datatype is wrong ( Id in the example project is an integer, it looks like a string in your project, Price should be a decimal and not a string, ...)
Whats the HTTP Response code ( if above didn't help), when you post the object. ( use a tool like fiddler). Tip, if your http response is a "bad request", then your data is probably invalid to continue in the action.
I incorrectly used http://localhost:/ for the POST instead of https://localhost:/Products
I have a Web API service that I'm trying to access via the console using RestSharp. My RestSharp code looks like this:
RestClient client = new RestClient(baseUrlString);
RestRequest request = new RestRequest("controllername/actionname");
request.RequestFormat = DataFormat.Json;
ProcessQuestion model = new ProcessQuestion()
{
Id = "123456",
InstanceId = "123",
UniqueId = "bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626",
PostedAnswer = new Dictionary<string, string>() { { "question_7907_1", "selected" }, { "question_7907_2", "selected" } }
};
request.AddBody(model);
var response = client.Execute(request)
My Web API action takes a model that has the same parameters as the above model. When the call executes, the binding fails and the parameter is null. I suspect this is due to the RestRequest.AddBody method prepending application/json to the body value as shown below:
{application/json={"Id":"123456","InstanceId":"123","UniqueId":"bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626","PostedAnswer":{"question_7907_1":"selected","question_7907_2":"selected"}}}
If I post using Fiddler the body binds to the model properly. Below is the body value I provided in Fiddler:
{'Id':'123456','InstanceId':'123','Uniqueid':'bfb16a18-d0d6-46ab-a5b3-2f0ebbfe8626','PostedAnswer':{'question_7907_1':'selected','question_7907_2':'selected'}}
Note that the body value in fiddler is the same with the exception of prepending the application/json key.
Also to note: I've tried what seems like everything...I've separated the parameters out in the action, used FromBody and FromUri attributes, tried custom DictionaryModelBinder's, tried custom ValueBinders, tried changing the way I'm using RestSharp (AddParameter with a RequestBody parameter, AddObject, different URL styles, etc.).
Has anyone else encountered this, and if so, did you solve it? I chose Web API for this service with hopes the model binding would work as it does in MVC, but I'm seeing that isn't the case.
Thanks
EDIT (resolved):
RestSharp automatically uses the JsonSerializer for objects passed in the AddBody method. I figured I was missing something simple, and indeed I was... Adding the Method.Post parameter to the RestRequest instantiation solved the problem.
Specify the method when creating the request:
RestRequest request = new RestRequest("controllername/actionname", Method.POST);
Not sure what the default serializer is for body - you can try making it explicit:
request.AddBody(request.JsonSerializer.Serialize(model));
I'm not sure where the 'application/json' is coming from - that's the Content-Type header you should be sending with your request, definitely not part of the body. So do this instead:
request.AddHeader("Content-type", "application/json; charset=utf-8");
If this doesn't help, try making your code as similar to the example on their site as possible. Try removing complexity (even if it means changing the required functionality) - get it to a point when it works and build additional functionality on that.
