如何删除“在json字符串中？

Question

我被一个模块击中了一个多星期，我有一个包含用户名和密码的登录页面，我需要将我的值传递给 Web 服务以检查登录。我的 Web 服务只包含一个名为“Param”的参数名称，我需要将值传递给“Param”。但是，当我输入有效的用户名和密码时，调用 Web 服务时没有问题卡住失败，这只是因为在我将值传递到登录页面时添加了这个 &quot 附加文本

这里是我在 Nslog 中打印的输出：

{"login_values":{"\"password":"xxxxx@1234","\"loginid":"xxxxxxx@gmail.com"}}

我的示例代码：

    NSString *login = self.username.text;
    NSString *password = self.password.text;
    NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
    [dict setValue:login forKey:@"loginid"];
    [dict setValue:password forKey:@"password"];
    NSError *error;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error];
    NSString *resultAsString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSLog(@"jsonData as string:\n%@", resultAsString);
    NSData *jsonData1 = [NSJSONSerialization dataWithJSONObject:dict options:0 error:&error];
    NSString *addnewuser_values = [[NSString alloc]initWithData:jsonData1 encoding:NSUTF8StringEncoding];
    NSString *append = [NSString stringWithFormat:@"{\"login_values\":"];
    NSString *slash = [NSString stringWithFormat:@"}"];
    NSString *append1 = [NSString stringWithFormat:@"%@%@%@",append,addnewuser_values,slash];
   NSString *modStr=[[append1 stringByReplacingOccurrencesOfString:@""" withString:@""]stringByReplacingOccurrencesOfString:@"," withString:@" "];
    NSLog(@"locginCheck_method:\n%@",append);
    request.param = modStr;

我需要删除那个“”

Answer 1

像下面这样使用stringByReplacingOccurrencesOfString api：-

NSString *modStr=[[jsonStr stringByReplacingOccurrencesOfString:@""" withString:@""]stringByReplacingOccurrencesOfString:@"," withString:@" "];

输出：-

{login_values:{password:xxxxx@1234 loginid:xxxxxxx@gmail.com}}

Answer 2

- (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement

看看这对你有没有帮助
