如何在角度转换请求中将对象字符串转换为 JSON 对象

How to convert string of objects to JSON object in angular transformRequest

本文关键字：对象 转换 字符串 JSON 请求      更新时间：2023-09-26

所以我收到这个字符串：

{"id":"0-worfebvjyyvqjjor","size":17,"price":921,"face":"( .-.)","date":"Mon Jan 04 2016 22:55:30 GMT+0000 (GMT Standard Time)"}
{"id":"1-ifma3yxxccgzaor","size":19,"price":98,"face":"( .o.)","date":"Fri Jan 08 2016 16:11:25 GMT+0000 (GMT Standard Time)"}
{"id":"2-sa3iurvt4hv0lik9","size":14,"price":659,"face":"( `·´ )","date":"Sun Jan 03 2016 06:20:28 GMT+0000 (GMT Standard Time)"}
{"id":"3-bc3tf55q9vx11yvi","size":33,"price":361,"face":"( ° ͜ ʖ °)","date":"Fri Jan 01 2016 22:49:22 GMT+0000 (GMT Standard Time)"}

在控制台.log（数据）中：

var WareHouseResource = $resource('/api/products?limit=10', {}, {
    query: {
        method: 'GET',
        isArray: false,
        transformResponse: function(data) {
            console.log(data);
        }
    }
});

如何将数据转换为 JSON 数组？我已经尝试过JSON.parse（data），但它抛出了一个错误。

如果要将数据作为数组，则可能需要将isArray设置为 true 

var WareHouseResource = $resource('/api/products?limit=10', {}, {
    query: {
        method: 'GET',
        isArray: true
    }
});

这是假设您收到的字符串表示形式采用有效格式。我可以看到每个对象之后都缺少,。这是意料之中的吗？如果是，您可能希望将}替换为},，将它们包装在"[]"中，然后在变压器中执行angular.fromJson(data)。

这里有一个可以做到这一点的 plunker：https://plnkr.co/edit/ZGLK7PTclapVNwuIlM1T?p=preview

你需要使用 angular.fromJson（）。所以 

var WareHouseResource = $resource('/api/products?limit=10', {}, {
    query: {
        method: 'GET',
        isArray: false,
        transformResponse: function(data) {
            console.log(angular.fromJson(data));
        }
    }
});

var items=[{"id":"0-worfebvjyyvqjjor","size":17,"price":921,"face":"( .-.)","date":"Mon Jan 04 2016 22:55:30 GMT+0000 (GMT Standard Time)"},
{"id":"1-ifma3yxxccgzaor","size":19,"price":98,"face":"( .o.)","date":"Fri Jan 08 2016 16:11:25 GMT+0000 (GMT Standard Time)"},
{"id":"2-sa3iurvt4hv0lik9","size":14,"price":659,"face":"( `·´ )","date":"Sun Jan 03 2016 06:20:28 GMT+0000 (GMT Standard Time)"},
{"id":"3-bc3tf55q9vx11yvi","size":33,"price":361,"face":"( ° ͜ ʖ °)","date":"Fri Jan 01 2016 22:49:22 GMT+0000 (GMT Standard Time)"}]
alert(angular.fromJson(items))
