估计你和我遇到的问题是一样的。 解决方法，使用jquery的param方法 包装参数就好了 1. header配置为 x-www-formxxxxx.... [图片] 2. 包装参数 [图片] reqData = this._param(reqData);其中 _param 就是 jquery的$.param方法 copy过来就好。 [代码]_param: [代码][代码]function[代码] [代码](a, traditional) {[代码][代码]        [代码][代码]var[代码] [代码]class2type = {};[代码][代码]        [代码][代码]var[代码] [代码]toString = class2type.toString;[代码][代码]        [代码][代码]var[代码] [代码]hasOwn = class2type.hasOwnProperty;[代码] [代码]        [代码][代码]function[代码] [代码]toType(obj) {[代码][代码]            [代码][代码]if[代码] [代码](obj == [代码][代码]null[代码][代码]) {[代码][代码]                [代码][代码]return[代码] [代码]obj + [代码][代码]""[代码][代码];[代码][代码]            [代码][代码]}[代码][代码]            [代码][代码]// Support: Android <=2.3 only (functionish RegExp)[代码][代码]            [代码][代码]return[代码] [代码]typeof[代码] [代码]obj === [代码][代码]"object"[代码] [代码]|| [代码][代码]typeof[代码] [代码]obj === [代码][代码]"function"[代码] [代码]?[代码][代码]                [代码][代码]class2type[toString.call(obj)] || [代码][代码]"object"[代码] [代码]:[代码][代码]                [代码][代码]typeof[代码] [代码]obj;[代码][代码]        [代码][代码]}[代码] [代码]        [代码][代码]var[代码] [代码]isFunction = [代码][代码]function[代码] [代码]isFunction(obj) {[代码][代码]            [代码][代码]// Support: Chrome <=57, Firefox <=52[代码][代码]            [代码][代码]// In some browsers, typeof returns "function" for HTML <object> elements[代码][代码]            [代码][代码]// (i.e., `typeof document.createElement( "object" ) === "function"`).[代码][代码]            [代码][代码]// We don't want to classify *any* DOM node as a function.[代码][代码]            [代码][代码]return[代码] [代码]typeof[代码] [代码]obj === [代码][代码]"function"[代码] [代码]&& [代码][代码]typeof[代码] [代码]obj.nodeType !== [代码][代码]"number"[代码][代码];[代码][代码]        [代码][代码]};[代码] [代码]        [代码][代码]var[代码][代码]            [代码][代码]rbracket = /\[\]$/,[代码][代码]            [代码][代码]rCRLF = /\r?\n/g,[代码][代码]            [代码][代码]rsubmitterTypes = /^(?:submit|button|image|reset|file)$/i,[代码][代码]            [代码][代码]rsubmittable = /^(?:input|select|textarea|keygen)/i;[代码] [代码]        [代码][代码]function[代码] [代码]buildParams(prefix, obj, traditional, add) {[代码][代码]            [代码][代码]var[代码] [代码]name;[代码] [代码]            [代码][代码]if[代码] [代码](Array.isArray(obj)) {[代码] [代码]                [代码][代码]// Serialize array item.[代码][代码]                [代码][代码]obj.forEach([代码][代码]function[代码] [代码](v, i) {[代码][代码]                    [代码][代码]if[代码] [代码](traditional || rbracket.test(prefix)) {[代码] [代码]                        [代码][代码]// Treat each array item as a scalar.[代码][代码]                        [代码][代码]add(prefix, v);[代码] [代码]                    [代码][代码]} [代码][代码]else[代码] [代码]{[代码] [代码]                        [代码][代码]// Item is non-scalar (array or object), encode its numeric index.[代码][代码]                        [代码][代码]buildParams([代码][代码]                            [代码][代码]prefix + [代码][代码]"["[代码] [代码]+ ( [代码][代码]typeof[代码] [代码]v === [代码][代码]"object"[代码] [代码]&& v != [代码][代码]null[代码] [代码]? i : [代码][代码]""[代码] [代码]) + [代码][代码]"]"[代码][代码],[代码][代码]                            [代码][代码]v,[代码][代码]                            [代码][代码]traditional,[代码][代码]                            [代码][代码]add[代码][代码]                        [代码][代码]);[代码][代码]                    [代码][代码]}[代码][代码]                [代码][代码]});[代码] [代码]            [代码][代码]} [代码][代码]else[代码] [代码]if[代码] [代码](!traditional && toType(obj) === [代码][代码]"object"[代码][代码]) {[代码] [代码]                [代码][代码]// Serialize object item.[代码][代码]                [代码][代码]for[代码] [代码](name [代码][代码]in[代码] [代码]obj) {[代码][代码]                    [代码][代码]buildParams(prefix + [代码][代码]"["[代码] [代码]+ name + [代码][代码]"]"[代码][代码], obj[name], traditional, add);[代码][代码]                [代码][代码]}[代码] [代码]            [代码][代码]} [代码][代码]else[代码] [代码]{[代码] [代码]                [代码][代码]// Serialize scalar item.[代码][代码]                [代码][代码]add(prefix, obj);[代码][代码]            [代码][代码]}[代码][代码]        [代码][代码]}[代码] [代码]        [代码][代码]// Serialize an array of form elements or a set of[代码][代码]        [代码][代码]// key/values into a query string[代码][代码]        [代码][代码]var[代码] [代码]param = [代码][代码]function[代码] [代码](a, traditional) {[代码][代码]            [代码][代码]var[代码] [代码]prefix,[代码][代码]                [代码][代码]s = [],[代码][代码]                [代码][代码]add = [代码][代码]function[代码] [代码](key, valueOrFunction) {[代码] [代码]                    [代码][代码]// If value is a function, invoke it and use its return value[代码][代码]                    [代码][代码]var[代码] [代码]value = isFunction(valueOrFunction) ?[代码][代码]                        [代码][代码]valueOrFunction() :[代码][代码]                        [代码][代码]valueOrFunction;[代码] [代码]                    [代码][代码]s[s.length] = encodeURIComponent(key) + [代码][代码]"="[代码] [代码]+[代码][代码]                        [代码][代码]encodeURIComponent(value == [代码][代码]null[代码] [代码]?
