Question

你好我们面临与将字符串转换为json相关的问题。这是我的字符串：

[
    {
        "SCHEME_NAME": "FUG RSA SCHEME",
        "Investment_Value": -46719.00201558,
        "Bid_Price": 2.2566,
        "Total_Contributions": 0,
        "Growth": -46719.00201558,
        "INVESTOR_ID": 5613,
        "PFA_SCHEMEID": 1
    },
    {
        "MONTH_NAME": "Balance as at 07-07-2016",
        "EMPLOYEE_CONTRIBUTION": 3433764.77,
        "EMPLOYER_CONTRIBUTION": 4381387.29,
        "TOTAL_VALUE": 7815152.06,
        "TOTAL_UNITS": 2782788.3885,
        "TOTAL_FEE": 0,
        "TOTAL_CONTRIBUTION": 7815152.06,
        "Voluntary": "0.00"
    },
    {
        "MONTH_NAME": "July 2016",
        "EMPLOYEE_CONTRIBUTION": 0,
        "EMPLOYER_CONTRIBUTION": 0,
        "TOTAL_VALUE": 0,
        "TOTAL_UNITS": -20703.2713,
        "TOTAL_FEE": 0,
        "TOTAL_CONTRIBUTION": 0,
        "Voluntary": "0.00"
    }
]

如何将其转换为JSON？请帮帮我。

Answer 1

试试这个：

NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

Answer 2

NSDictionary *jsonResult = [NSJSONSerialization JSONObjectWithData:data1 options:NSJSONReadingMutableContainers error:&error];

Answer 3

JSON只不过是用括号{}括号括起来的一对键/值对，但是你错过了一对。您还需要一个封闭的根{}花括号并指定数组的键，目前我已根据您的要求指定了响应，然后JSON才有效。

{
    "response": [
     ...
    ]   
}

然后你可以用@SaintThread提到的内容进行转换。

Answer 4

它已经是JSON格式。我试图将字符串转换为json。我得到了它。但结果与它的问题相同。

将字符串转换为json时，它应该位于\＆＃34; Key \＆＃34;：\＆＃34; Value \＆＃34;或\＆＃34;键\＆＃34;：值

NSString *str=@"[{\"SCHEME_NAME\":\"FUG RSA SCHEME\",\"Investment_Value\":-46719.00201558,\"Bid_Price\":2.2566,\"Bid_Price\":\"2.2566\",\"Total_Contributions\":0,\"Growth\":-46719.00201558,\"INVESTOR_ID\":5613,\"PFA_SCHEMEID\":1},{ \"MONTH_NAME\": \"Balance as at 07-07-2016\",\"EMPLOYEE_CONTRIBUTION\": 3433764.77,\"EMPLOYER_CONTRIBUTION\": 4381387.29,\"TOTAL_VALUE\": 7815152.06,\"TOTAL_UNITS\": 2782788.3885,\"TOTAL_FEE\": 0,\"TOTAL_CONTRIBUTION\": 7815152.06,\"Voluntary\": \"0.00\"},{\"MONTH_NAME\": \"July 2016\",\"EMPLOYEE_CONTRIBUTION\": 0,\"EMPLOYER_CONTRIBUTION\":0,\"TOTAL_VALUE\":0,\"TOTAL_UNITS\": -20703.2713,\"TOTAL_FEE\": 0,\"TOTAL_CONTRIBUTION\": 0,\"Voluntary\": \"0.00\"}]";
NSData *dataStr = [str dataUsingEncoding:NSUTF8StringEncoding];
id jsonData = [NSJSONSerialization JSONObjectWithData:dataStr options:0 error:nil];
NSLog(@"The converted string to json is %@",jsonData);

现在打印结果是

The converted string to json is (
    {
    "Bid_Price" = "2.2566";
    Growth = "-46719.00201558";
    "INVESTOR_ID" = 5613;
    "Investment_Value" = "-46719.00201558";
    "PFA_SCHEMEID" = 1;
    "SCHEME_NAME" = "FUG RSA SCHEME";
    "Total_Contributions" = 0;
},
    {
    "EMPLOYEE_CONTRIBUTION" = "3433764.77";
    "EMPLOYER_CONTRIBUTION" = "4381387.29";
    "MONTH_NAME" = "Balance as at 07-07-2016";
    "TOTAL_CONTRIBUTION" = "7815152.06";
    "TOTAL_FEE" = 0;
    "TOTAL_UNITS" = "2782788.3885";
    "TOTAL_VALUE" = "7815152.06";
    Voluntary = "0.00";
},
    {
    "EMPLOYEE_CONTRIBUTION" = 0;
    "EMPLOYER_CONTRIBUTION" = 0;
    "MONTH_NAME" = "July 2016";
    "TOTAL_CONTRIBUTION" = 0;
    "TOTAL_FEE" = 0;
    "TOTAL_UNITS" = "-20703.2713";
    "TOTAL_VALUE" = 0;
    Voluntary = "0.00";
}
)

然后当我将数据导入数组

NSArray *arrJson = [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:nil];
NSLog(@"The arrjson is %@",arrJson);

打印结果是

The arrjson is (
    {
    "Bid_Price" = "2.2566";
    Growth = "-46719.00201558";
    "INVESTOR_ID" = 5613;
    "Investment_Value" = "-46719.00201558";
    "PFA_SCHEMEID" = 1;
    "SCHEME_NAME" = "FUG RSA SCHEME";
    "Total_Contributions" = 0;
},
    {
    "EMPLOYEE_CONTRIBUTION" = "3433764.77";
    "EMPLOYER_CONTRIBUTION" = "4381387.29";
    "MONTH_NAME" = "Balance as at 07-07-2016";
    "TOTAL_CONTRIBUTION" = "7815152.06";
    "TOTAL_FEE" = 0;
    "TOTAL_UNITS" = "2782788.3885";
    "TOTAL_VALUE" = "7815152.06";
    Voluntary = "0.00";
},
    {
    "EMPLOYEE_CONTRIBUTION" = 0;
    "EMPLOYER_CONTRIBUTION" = 0;
    "MONTH_NAME" = "July 2016";
    "TOTAL_CONTRIBUTION" = 0;
    "TOTAL_FEE" = 0;
    "TOTAL_UNITS" = "-20703.2713";
    "TOTAL_VALUE" = 0;
    Voluntary = "0.00";
}
)

试试这个在线json查看器：

您可以在线格式化和查看

这是一种格式

    [
  {
    "SCHEME_NAME": "FUG RSA SCHEME",
    "Investment_Value": -46719.00201558,
    "Bid_Price": 2.2566,
    "Total_Contributions": 0.00,
    "Growth": -46719.00201558,
    "INVESTOR_ID": 5613,
    "PFA_SCHEMEID": 1
  }
,
  {
    "MONTH_NAME": "Balance as at 07-07-2016",
    "EMPLOYEE_CONTRIBUTION": 3433764.77,
    "EMPLOYER_CONTRIBUTION": 4381387.29,
    "TOTAL_VALUE": 7815152.06,
    "TOTAL_UNITS": 2782788.3885,
    "TOTAL_FEE": 0.00,
    "TOTAL_CONTRIBUTION": 7815152.06,
    "Voluntary": "0.00"
  },
  {
    "MONTH_NAME": "July 2016",
    "EMPLOYEE_CONTRIBUTION": 0.00,
    "EMPLOYER_CONTRIBUTION": 0.00,
    "TOTAL_VALUE": 0.00,

    "TOTAL_FEE": 0.00,
    "TOTAL_CONTRIBUTION": 0.00,
