Gson MalformedJsonException

Question

我正在尝试为OperatorModel[]分配一个JSON字符串，但我得到了MalformedJsonException。

字符串

  

[{\＆＃34;简档\＆＃34;：\＆＃34; 69c02265-ABCA-4716-8a2f-ac5d642f876a \＆＃34; \＆＃34; DisplayName的\＆＃34;：\ ＆＃34; baman \＆＃34; \＆＃34; IsAvailable \＆＃34;：假，\＆＃34;图像\＆＃34;：空}，{\＆＃34;简档\＆＃ 34;：\＆＃34; 1f6bdd5b-c4ea-4566-bc56-ee2f58acece8 \＆＃34; \＆＃34; DisplayName的\＆＃34;：\＆＃34; nayanthara \＆＃34; \＆＃ 34; IsAvailable \＆＃34;：假，\＆＃34;图像\＆＃34;：空}]

OperatorModel

public class OperatorModel {
    public String ProfileId;
    public String DisplayName;
    public Boolean IsAvailable;
    public String Image;
}

方式

private void displayAllOperators(String AllOperators, String ActiveOperators){

    operatorListNew.removeAll(operatorListNew);
    Gson gson =new Gson();

    OperatorModel[] items = gson.fromJson(AllOperators, OperatorModel[].class);

    if (items.length>0){
        for (int g=0; g< items.length; g++){

        }
    }
}

Answer 1

你的json字符串无效.Json字符串总是以JsonObject开头而不是JsonArray ex。{＆＃34; ss＆＃34;：[]}

请检查您的json是否有效here

有效的json如下

{
    "array_name": [{
        "ProfileId": "69c02265-abca-4716-8a2f-ac5d642f876a",
        "DisplayName": "baman",
        "IsAvailable": false,
        "Image": null
    }, {
        "ProfileId": "1f6bdd5b-c4ea-4566-bc56-ee2f58acece8",
        "DisplayName": "nayanthara",
        "IsAvailable": false,
        "Image": null
    }]
}

创建你的json Pojo类here

Answer 2

此json字符串无效。

应该是这样的 [{"\"ProfileId\"":等。

Answer 3

尝试更改

此

要

[{\"ProfileId\":\"69c02265-abca-4716-8a2f-ac5d642f876a\",\"DisplayName\":\"baman\",\"IsAvailable\":false,\"Image\":null},{\"ProfileId\":\"1f6bdd5b-c4ea-4566-bc56-ee2f58acece8\",\"DisplayName\":\"nayanthara\",\"IsAvailable\":false,\"Image\":null}]
