所以我反复出现此错误:
“字符0周围的值无效。”
我已经用尽所有方法来调试它。基本上,该API在Postman中可以正常工作,但是通过代码却无法正常工作。邮递员是本地设置的,因此我无法在此处共享。无论如何,这是我的代码:
let headers = ["Content-Type": "application/json",
"Accept": "application/json"]
let params = ["userId":"98", "candidateId":"4"]
Alamofire.request(url, method: .post, parameters: params, encoding:
JSONEncoding.default, headers: headers).response { response in
if let data = response.data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: [.allowFragments]) as? [String: Any]
completion(json , nil)
} catch {
completion(nil, response.error)
}
}else{
completion(nil, response.error)
}
}
我尝试过responseString,responseJSON和response和JSONSerialization我已经将选项与.allowFragments,.mutableContainers和.mutableLeaves一起使用,但是没有用。我什至尝试给它提供标头,尽管Postman调用不包含标头,但再次失败了。我该怎么办,请帮忙。下面是响应对象的快照:
这是我执行此操作后获得的responseString即时消息:
String(data: data, encoding: .utf8)
&这是我删除.allowFragments时的错误:
Error Domain = NSCocoaErrorDomain代码= 3840“ JSON文本未启动 带有数组或对象,并具有允许未设置片段的选项。” UserInfo = {NSDebugDescription = JSON文本不是以数组开头或 对象和允许未设置片段的选项。}

问题出在您的标题上
let headers = ["Content-Type": "application/json",
"Accept-Type": "application/json"]
Accept-Type
不是有效的HTTP标头。您需要的是Accept
let headers = ["Content-Type": "application/json",
"Accept": "application/json"]

就我而言:
更改内容类型的标头
headers = [
"Content-Type": "application/json",
"Authorization" : "Token"
]
收件人
headers = [
"Content-Type": "application/x-www-form-urlencoded",
"Authorization" : "Token"
]
工作!
