我的AJAX POST请求由于某种原因将numeric
数据发送到我的服务器string
...这是我的数据和AJAX请求:
var data = {
projectId: $("#projectId").val(),
startDate: $("#startDate").val(),
endDate: $("#endDate").val(),
num_auto_tests: Number($("#num_auto_tests").val()),
num_manual_tests: Number($("#num_manual_tests").val()),
num_passed_tests: Number($("#num_passed_tests").val()),
num_failed_tests: Number($("#num_failed_tests").val()),
num_unran_tests: Number($("#num_unran_tests").val()),
test: 3
};
AJAX查询:
$.ajax({
type: "POST",
dataType: "json",
url: "/addreport/+ data.projectId",
data: data,
success: function() {
console.log('success');
}
});
console.log(typeof(data.num_auto_tests)); //returns `number`
服务器端返回:
{ projectId: 'FDIC-88445',
startDate: '',
endDate: '',
num_auto_tests: '3',
num_manual_tests: '3',
num_passed_tests: '3',
num_failed_tests: '3',
num_unran_tests: '3',
test: '3' }
如您所见,应该是数字的值是服务器端的所有字符串......
有谁知道发生了什么?
提前致谢!

您的服务器收到HTTP协议中的帖子,难怪您的服务器端收到一个字符串,因为您正在执行的操作不是类型安全的。这实际上是预期的行为,如果您希望元素变为数字,那么将参数转换为数字,确切的方法取决于您使用的服务器端语言/框架。
编辑: 您可以做两件事来解决您的问题:
您可以创建一个数字处理程序/转换器,如下所示:
function detectNumeric(obj) {
for (var index in obj) {
if (!isNaN(obj[index])) {
obj[index] = Number(obj[index]);
} else if (typeof obj === "object") {
detectNumeric(obj[index]);
}
}
}
并为您想要以这种方式处理的任何对象调用此函数,或
var my_object = {
position: 1,
id: "500",
text: "hello world",
greeting: "100, good day to you",
book: "nineteen eighty four"
};
// iterates over an object's properties
// and converts numbers as strings to numbers
function detectNumeric(obj) {
for (var index in obj) {
// if object property value *is* a number, like 1 or "500"
if (!isNaN(obj[index])) {
// convert it to 1 or 500
obj[index] = Number(obj[index]);
}
// to do: explain what this does
// else if (typeof obj === "object") {
// detectNumeric(obj[index]);
// }
}
console.log(my_object)
}
// call function
detectNumeric(my_object);

我认为POST请求的默认内容类型是对其进行url-encode。这实质上将所有内容都转换为字符串值,并按原样检索。根据您使用的服务器端体系结构,可以使用不同的内容类型(或随后手动支持),例如使用可以保留对象结构和类型的内容类型application/json
。

我用JSON.stringify
解决了这个问题。 PFB我的Ajax呼叫:
var settings = {
"url": "http://localhost:12345/docker/scale",
"type": "POST",
"headers": {
"Content-Type": "application/json"
},
"data": JSON.stringify({ "scale": { "desired-instances": 123 } })
}
$.ajax(settings).done(function (response) {
console.log(response);
});
通过执行此值仅作为整数传递,因此不需要在服务器端代码中进行任何更改。

这是我的解码器,它可以处理多维数组/对象
//running the object through tests
function tryParsingType(unknownObj) {
if (unknownObj.constructor.name === "String" && !isNaN(parseFloat(unknownObj)))
return parseFloat(unknownObj);
else if (unknownObj.constructor.name === "String" && (unknownObj === "true" || unknownObj === "false"))
return unknownObj === "true";
else if (unknownObj.constructor.name === "Array" || unknownObj.constructor.name === "Object")
tryParsingTypes(unknownObj);
return unknownObj;
}
//works for generic objects and arrays
function tryParsingTypes(genericObj) {
var type = genericObj.constructor.name;
if (!(type === "Array" || type === "Object"))
return;
var keys = Object.keys(genericObj);
for (var i = 0; i < keys.length; i++) {
var object = genericObj[keys[i]];
genericObj[keys[i]] = tryParsingType(object);
}
}
//example code below
var testObj = {
"key5": "-1",
"key6": "-132.3123",
"key7": "3421",
"key10": "true",
"key11": "false",
"key12": 'true',
"key13": 'false',
"key14": {
"key1": {
"key1": "true",
"key2": {
"key1337": "-432.2342",
"key321": {
"key1": "-1231.2",
"key2": "false"
}
}
},
"key2": ["true", "false"],
"key3": 2.5,
"key4": "3",
"key5": "40",
"key6": "40.99441"
},
"key15": [1, 2, 2.5, "3", "40", "40.99441"]
};
var testArr = [1, 2, 3, 4, 5, "6", "7", "8", "9", "10", true, false, "true", "false", {
"key1": 1,
"key2": 2,
"key3": 2.5,
"key4": "3",
"key5": "40",
"key6": "40.99441"
}, [1, 2, 2.5, "3", "40", "40.99441", ["1", "2"]]];
tryParsingTypes(testObj);
tryParsingTypes(testArr);
console.log({
"testObj": testObj,
"testArr": testArr
});
