With the following JSON, how to decode with ZIO JSON?

I am new to Deno and have the following simple code...
const getCOP = async()=>{
const resp = await fetch("....", {
headers: {
accept: "application/json",
apiKey
},
});
return await resp.body;
}
let resp = {}
return new Response(resp.body, {
status: resp.status,
headers: {
"content-type": "application/json",
},
});
resp.body = await getCOP();
resp.status = 200;
It returns
{
"success": true,
"timestamp": 1675621083,
"base": "COP",
"date": "2023-02-05",
"rates": {
"EUR": 0.000199,
"GBP": 0.000179,
"USD": 0.000216
}
}
What I would like to do would be the equivalent of this in normal JS...
return {
rate : resp.body.rates,
copPerDollar : 1 / resp.body.rates.USD
}
Of course this doesn't seem to work because instead of an actual json obj it is a readable stream. How do I transform this stream into a json object and then restream it to the body of the sent request?
I'm trying to generate pacts from spring cloud contracts as shown at the documentation. It works just find when the response body root is a json, however when I'm trying to generate a pact that return an array of jsons it generates an empty body. I´ve tried using groovy dsl with String format """[{}...]""" and using DslProperty [value()...]. Here are my contracts:
With string format
Contract.make {
description "should return a list of dummy object with dummy value. Generates pact with empty json"
request {
method GET()
url("/dummy")
}
response {
body("""[{"value": "Hi! I'm a dummy object ;)"}]""")
headers {
contentType applicationJson()
}
status 200
}}
With DslProperty
Contract.make {
description "should return a list of dummy object with dummy value. Generates pact with empty body list"
request {
method GET()
url("/dummy")
}
response {
body([value(value: "Hi! I'm a dummy object ;)")])
headers {
contentType applicationJson()
}
status 200
}}
And that's the file generate at target/pacts

"name": "Provider"
},

"name": "Consumer"

"interactions": [

and that's my plugin configuration

While debugging throgh the plugin I've seen that what is happening respectively is:
- When declaring body as “”” [{...}] “”” Pact converter assumes that the body is an String instance so it goes through traverse method at org.springframework.cloud.contract.verifier.spec.pact.BodyConverter. And since it starts with [ it is not parsed.
org.springframework.cloud.contract.verifier.spec.pact.BodyConverter
private static DslPart traverse(Object value, DslPart parent, Closure dslPropertyValueExtractor) {
...
if (v instanceof String) {
v = v.trim()
if (v.startsWith("{") && v.endsWith("}")) {
try {
v = jsonSlurper.parseText(v as String)
}
catch (JsonException ex) { /*it wasn't a JSON string after all...*/
}
}
}
...
On the other hand, when going through the plugin code using the DslProperty I have an object like [DslProperty{clientValue=DslProperty}]. The first DslProperty is being extracted but since the content is another DslProperty and there’s no recursive extraction I end up with an empty body because v isn’t an instance of the Gstring, String, Number, Map, Collection. So I get an empty body again.
org.springframework.cloud.contract.verifier.spec.pact.BodyConverter
private static void processCollection(Collection values, PactDslJsonArray jsonArray, Closure dslPropertyValueExtractor) {
values.forEach({
Object v = it
if (v instanceof DslProperty) {
v = dslPropertyValueExtractor(v)
}
if (v instanceof GString) {
v = ContentUtils.extractValue(v, dslPropertyValueExtractor)
}
if (v == null) {
jsonArray.nullValue()
}
else if (v instanceof String) {
jsonArray.string(v)
}
else if (v instanceof Number) {
jsonArray.number(v)
}
else if (v instanceof Map) {
PactDslJsonBody current = jsonArray.object()
traverse(v, current, dslPropertyValueExtractor)
current.closeObject()
}
else if (v instanceof Collection) {
PactDslJsonArray current = jsonArray.array()
traverse(v, current, dslPropertyValueExtractor)
current.closeArray()
}
})
}
I've published an example at https://github.com/brjt23/contract-to-pact/tree/master in case more info about how I did build the project is required.
Is there something I'm doing wrong on defining my groovy contract files? I guess I missunderstood something about how the response body should be defined.
You need to create an array of groovy objects in your body like this:
body([
[value: "Object1"],
[value: "Object2"]
])
This way spring cloud contracts will generate the correct code needed for your contracts.
I'm following the facebook messenger develop QuickStart to create a Node.js project, and I improved it to work in quick reply. Then when I tried the Generic Template and List Template, but it didn't work.
As the following source code, when I input the work "generic" or "list", the messenger should reply me with the template messege. But there was nothing happened.
} else if (received_message.text === 'generic') {
console.log('generic in');
response = {
"attachment":{
"type":"template",
"payload":{
"template_type":"generic",
"elements":[
{
"title":"Welcome!",
"image_url":"http://webapplication120181023051009.azurewebsites.net/colorcar1.jpg",

},

},{

}

Sorry, I forgot to add the url into whiltelist.
Suppose I have a contract like this specified in groovy:
org.springframework.cloud.contract.spec.Contract.make {
request {
method "GET"
url "/api/profiles"
headers {
header('Accept': 'application/json;charset=UTF-8')
header('Content-Type': 'application/json;charset=UTF-8')
}
}
response {
status 200
headers {
header('Content-Type': 'application/json;charset=UTF-8')
}
body(
value(
stub(
'''\
[
{
"profile": "profile1",
"myMap": {}
},
{
"profile": "profile2",
"myMap": {
"12345": "FOO",
"asdf": "BAR"
}
}
]
'''
),
test(
[
[
"profile" : regex(nonEmpty()),
"myMap": [
[
??
]
]
]
]
)
)
)
}
}
Now I want to test that the map contains String to String entries where the values must not be empty. The map itself may be empty.
How can I test for dynamic key name?
On the response side of the contract you have to chose whether you're using the map notation or the string notation. If you want to do assertions on pieces of the response you have to embed those assertions inside the body or use the test matchers.
You can put the body as a multiline string and then write the testMatchers section
testMatchers{
jsonPath('$.[*].myMap', byCommand('assertKeys($it)'))
}
then it's enough for you to provide the assertion in the assertKeys method.
I have a dotnet core api that returns a FileContentResult..
return new FileContentResult(bytes, contentType)
{
FileDownloadName = Path.GetFileName(request.Filename)
};
Via postman I can read out the image perfectly fine. Now I want to read the image, via the aurelia fetch client, and show it in my html view. This is my function to retrieve the image from the api.
public image(filename: string) {
return this.http.fetch(AppConfiguration.base_url + 'assets/image',
{
method: 'post',
body: json({
filename: filename
})
});
}
I've tried to convert the blob in the response with this value converter. But I can't get that to work
Converter:
export class BlobToUrlValueConverter {
public toView(blob) {
return URL.createObjectURL(blob);
}
}
Viewmodel:
export class Dashboard {
public blob: any;
constructor(
public assets_service: AssetsService
) { }
async attached() {
let response = await this.assets_service.image('test.png');
this.blob = response.blob();
}
}
View
<div if.bind="blob">
${ blob | blobToUrl }
</div>
I'm not sure this is the right approach. Also not sure how handle the async request part of it either. What is the best way to get that image response to show in the html view? Lets say via a img tag?
I was close. Here is how I got the image to show.
Viewmodel:
export class Dashboard {
public url: string;
constructor(
public assets_service: AssetsService
) { }
async attached() {
let blob = await this.assets_service.image('test.png')
.then(response => response.blob());
this.url = URL.createObjectURL(blob);
}
}
View:
<div if.bind="url">
<img src.bind="url">
</div>
EDIT:
Found a better solution using parts written above:
The exported function that does the call (for reusability on both ts and html sides):
export function image_request(filename: string): Promise<Response> {
let http = new Http();
return http.fetch(<your-url-that-fetches-the-image>,
{
method: 'post',
body: json({
filename: filename
})
});
}
Value converter that uses above function
import { image_request } from './AssetsRequests';
export class ImageRequestValueConverter {
public toView(filename: string) {
return image_request(filename);
}
}
The important and most awesome part of the solution. Many thanks to http://www.sobell.net/aurelia-async-bindings/
for getting me on my way. You can override the binding behaviour. You can use this override to process async
Promise in a view in combination with a value converter.
export class AsyncImageBindingBehavior {
public bind(binding, source): void {
binding.originalupdateTarget = binding.updateTarget;
binding.updateTarget = (target) => {
// When we have a promise
if (typeof target.then === 'function') {
// Set temp value to loading so we know its loading
binding.originalupdateTarget('Loading...');
// Process the promise
target
.then(response => response.blob())
.then(blob => binding.originalupdateTarget(
URL.createObjectURL(blob)
));
}
else {
binding.originalupdateTarget(target);
}
};
}
unbind(binding) {
binding.updateTarget = binding.originalupdateTarget;
binding.originalupdateTarget = null;
}
}
Finally the view is very simple
<img src="${ 'test.png' | imageRequest & asyncImage }">
