Javascript - 读取格式为url的JSON字段

Question

REST API向我发送JSON，其中URL为字段。

如何使用Javascript阅读这些字段？ 这不起作用......

var json = JSON.parse(profile);

console.log(json["http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality"]); 

错误：

SyntaxError: Unexpected token o in JSON at position 1

JSON从api发回：

{
"issuer":"www.econtract.be",
"nameID":"00081007501",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality":"Hasselt",
"be:fedict:eid:idp:card-validity:end":"2023-03-03T00:00:00Z",
"be:fedict:eid:idp:card-number":"592548451825",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/privatepersonalidentifier":"00081007501",
"be:fedict:eid:idp:nationality":"Belg",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/dateofbirth":"2000-08-10T00:00:00Z",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/gender":"1",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/postalcode":"3511",  
etc....
}

问题解决了！谢谢@Mike

更改此代码：

var json = JSON.parse(profile);
console.log(json["http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality"]); 

到此代码：

console.log(profile["http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality"]);

感谢您的帮助！

观察：

您正在尝试解析JSON Object。无需再次解析JSON对象，因为在从API发回时已经解析了它。

工作演示

var profile = {
"issuer":"www.econtract.be",
"nameID":"00081007501",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality":"Hasselt",
"be:fedict:eid:idp:card-validity:end":"2023-03-03T00:00:00Z",
"be:fedict:eid:idp:card-number":"592548451825",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/privatepersonalidentifier":"00081007501",
"be:fedict:eid:idp:nationality":"Belg",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/dateofbirth":"2000-08-10T00:00:00Z",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/gender":"1",
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/postalcode":"3511"
};

console.log(profile["http://schemas.xmlsoap.org/ws/2005/05/identity/claims/locality"]);
