Question

这是UPS发货的webservices API。我收到了这个错误：

{“错误”：{“代码”：“4”，“描述”：“JSON语法错误”}}

AJAX代码：

  <script>          
        var formData = { "UPSSecurity": { "UsernameToken": { "Username":"xxx.com", "Password":"xxxxx" }, "ServiceAccessToken": { "AccessLicenseNumber":"1234D567DF67" } }, "RateRequest": { "Request": { "RequestOption":"Rate", "TransactionReference": { "CustomerContext":"Test saran" } }, "Shipment": { "Shipper": { "Name":"Saravanan", "ShipperNumber":"Y72A41", "Address": { "AddressLine":["2311 York Rd"], "City":"Sebastopol", "StateProvinceCode":"CA", "PostalCode":"95473", "CountryCode":"US" } }, "ShipTo": { "Name":"ShipToName", "Address": { "AddressLine":["195 N main st"], "City":"Sebastopol", "StateProvinceCode":"CA", "PostalCode":"95472", "CountryCode":"US" } }, "ShipFrom": { "Name":"ShipFromName", "Address": { "AddressLine":"2311 York Rd", "City":"Sebastopol","StateProvinceCode":"CA", "PostalCode":"95473", "CountryCode":"US" } }, "Service": { "Code":"03", "Description":"Express" }, "Package": { "PackagingType": { "Code": "02", "Description": "Rate" }, "Dimensions": { "UnitOfMeasurement": { "Code": "IN", "Description": "inches" }, "Length": "7", "Width": "5", "Height": "2" }, "PackageWeight": { "UnitOfMeasurement": { "Code": "Lbs", "Description": "pounds" }, "Weight": "10" } }, "ShipmentRatingOptions": { "NegotiatedRatesIndicator": "" } } } };

        $.ajax({
            type       : "POST",
            url        : "https://wwwcie.ups.com/rest/Rate",
            crossDomain: true,
            timeout    : 240000,
            data       : formData,
            dataType   : 'json',
            success    : function(response) 
            {
                alert("result="+response);
            }  
        }); 

    </script>

我不知道我哪里错了。但是这个请求通过“POST MAN”和“ARC”工具完美运行。请更新答案。

你没有发送JSON;当你给它一个对象时，jQuery的默认序列化是URI编码。要发送JSON，请将对象转换为JSON.stringify的字符串。您还应该使用contentType确定您发送的内容是JSON，所以：

contentType: 'application/json',
data       : JSON.stringify(formData),

如何解决JSON语法错误。如何得到回应？
