My apologies in advance for what is likely a basic question. Fetch and Json are new to be, as is the Corvid development environment. I am working to send JSON login information to another server via a fetch post. I have a short function (below) to do that. It calls another function that builds an array of login credentials it retrieves from a collection. I have verified that the login credentials are returned correction. No errors are reported in the debugger from this code.
How do I get at the response from the server? Nothing I have tried seems to work. Below is my current attempt.
export async function TestCode(event) { let loginarray = await getLoginCredentials();
console.log(loginarray); // I have verified login credtials coming back correctly. let url = [the url I am posting to];
Yes and yes to the support pages. But, as I said, this enviroment and language is new to me. About 30% does not land well. I have looked at @yisrael-wix 's example. However, when I try to view the example, all I see is the following:
Nothing else loads. I have no context. That is the entirety. I am sure it is useful, because others have referenced it. But, I cannot really make use of it, for some reason.
I did some additional reading on asynchronous code. I think that is a part of the issue I am having. I have made some adjustments to my code and now see where I need to put my code to capture the server response. But, the response I am getting back is nothing.
I have stripped the code to the bare basics to help me better understand. This is the current version:
export async function TestCode(event) {
let loginarray = await getLoginCredentials();
let jsonarray = JSON.stringify(loginarray);
console.log(loginarray); // I have verified login credentials coming back correctly.
let url = [the url I am posting to];
console.log(jsonarray);
fetch(url, {
“method”: “post”, body: jsonarray
})
.then((httpResponse) => {
console.log(httpResponse);
})
}

When you open the example up in your Wix Editor, you will need to enable Corvid (Dev Mode - Enable Corvid), then you will be able to see all the code in the http-functions.js file in the backend.
@givemeawhisky Thanks again. When I open it in the Wix editor and look at the code, I don’t think it is going to help me. I am needing examples of the fetch. All I see in this example are responses to fetches. Even searching the code for “fetch” I find only one instance. It is the first line that reads, “// This backend file exposes an API that replies to requests (fetch) from a client app.”
I take that to mean this backend that I am looking at is responding to the fetch. I’m clearly looking in the wrong place.
@givemeawhisky My bad. Sorry. I later saw there are 2 example apps. I found the app doing the fetching. Digging through the code still. But, I don’t think it answers the very basic question that I have.
Look at my above code. Look at just these two lines:
I believe this should collect the response from the fetch() post and put it in the console.log. Right? If the response comes back in json, I should still expect to see something in the log, right?
@skmedia Thanks much. That is similar to what I ended up doing. 2 aspects about it: 1) adding a 2nd .then() to ensure the json is decoded. 2) I also added a JSON.stringify() to make the console.log() readable. Thanks again.
