我试图在用户关闭窗口时进行此调用。
createCallRecord (data) {
let logData = {"chathist" : data , "uid": "1111" };
let headers = new HttpHeaders();
headers = headers.set("Content-Type", "application/json");
let options = { headers: headers };
return this.http.post(MY_URL, logData, options).subscribe(res => alert(res));
}
因为当用户关闭窗口时会调用此窗口,所以我不知道它是否成功发布。
发布后如何处理成功或错误?
目前,它没有提醒任何事情。
任何帮助将不胜感激!

您可以通过以下方式处理错误:
createCallRecord (data) {
let logData = {"chathist" : data , "uid": "1111" };
let headers = new HttpHeaders();
headers = headers.set("Content-Type", "application/json");
let options = { headers: headers };
return this.http.post(MY_URL, logData, options)
.subscribe(result =>
{
let value = result.json();
console.log(JSON.stringify(value));
}, err => { console.log(err); });
另一种选择是以这种方式使用处理程序功能:
createCallRecord (data) {
let logData = {"chathist" : data , "uid": "1111" };
let headers = new HttpHeaders();
headers = headers.set("Content-Type", "application/json");
let options = { headers: headers };
return this.http.post(MY_URL, logData, options)
.subscribe(res => this.resultHadler(res), err => this.errorHandler(err));
}
private resultHadler(res: any)
{
let value = res.json();
console.log(JSON.stringify(value));
}
private errorHandler(err: any)
{
console.log(err);
}
