简介：
你好。因此，我正在加密即将成为JavaScript对象的属性，以便将其发送到我的API。我使用的是带有secp256k1密钥的ECIES方案。这会在promise对象被发送到API之前返回它。我对多线程"；"东西"；在浏览器中(async wait)，我想知道它为什么这么做，以及如何解决这个问题。我相信这可能是一个更大问题的问题，并且这不能适当地将我从API检索到的非常相同的值与客户端值进行比较；｛Object Promise｝"；。如果这不能让我找到一个可行的解决方案，我将在另一个问题中发表这一点。在最后发布的第二个代码片段中，您将看到"；encryptMes"；函数，这就是返回Object Promise 的内容
Focus：为什么返回｛Object Promise｝，以及如何使它只返回一个常规Object？
相关HTML：
<form id="login-form" name ="signup-form">
<input class="login-form-field" type="text" name="user" placeholder="username">
<input class="login-form-field" type="text" name="email" placeholder="email">
<input class="login-form-field" type="password" name="dob" placeholder="date of birth">
<br>
<!--<button class="actionButton"></button>-->
<INPUT TYPE="button" class="button-success" NAME="button" Value="sign up" onClick="signupData(this.form)">
<br>
<div class="signup">
<a href="login.html">login</a>
</div>
</form>
<script LANGUAGE="JavaScript">
function signupData(form) //add to this script
{
console.log("signup data is starting");
var user = form.user.value;
var email = form.email.value;
var dob = form.dob.value;
console.log("checkpoint: 1");
genSKey();
console.log("checkpoint: 2");
console.log("checkpoint: 3");
var enUser = encryptMes(user);
//var enEmail = encryptMes(email);
var enDOB = encryptMes(dob);
var data = {name:"LifeNet", members:{}} //you added members to the same area in the object so it is always replacing members since it's the field of data
data.members[enUser] = {profilePic:{},enDOB, listeners:{}, listening:{}, friends:{}, requested:{}, blocked:{}, channel:false}
console.log("checkpoint: 3");
console.log({data});
apiPost({data});
//pass the signup function in here
//hash the variables and send to celox network
//console.log(JSON.stringify({data}));
//alert (`copy and save your Private Key to somewhere safe: ${skey}`);
//window.location.href= "login.html";
}
</script>
Borwserify之前构建的相关Javascript：
window.encryptMes = function(data)
{
//for this you need to get the sender's public key to encrypt the message
console.log("encryptmes: began");
var pkey = genPKey();
if (pkey === null || undefined)
{
console.log('You do not have a key pair');
}
var encryptedMes = eccrypto.encrypt(pkey, Buffer.from(data));
var enMes = encryptedMes.toString('hex');
console.log(encryptedMes); //could be this since it is not stringified when it goes into celox network
console.log(enMes);
return enMes;
}
window.getPKey = function()
{
var PKey = localStorage.getItem("pkey");
var pkey = JSON.parse(PKey);
console.log(pkey);
return pkey;
}
当然，在我的html文件中的脚本标记中，它会被发送到一个fetch post请求。我知道这不是问题所在，所以我没有把它包括在内

您需要等待Promise被解析，直到您可以使用结果为止。使用async/await。
window.encryptMes = async function(data)
{
// ...
var encryptedMes = await eccrypto.encrypt(pkey, Buffer.from(data));
var enMes = encryptedMes.toString('hex');
// ...
return enMes;
}
