wx.request 普通表单无法提交数组
发布于 5 年前 作者 yang44 17927 次浏览 来自 问答

‘content-type’: ‘application/x-www-form-urlencoded; charset=UTF-8’

当使用表单方式提交的时候，无法像浏览器一样传输数组。希望尽快修复。

wx.request({
    url: xxx, //仅为示例，并非真实的接口地址
    data: {
        "rs": "login",
        "rsargs": [ 'aaa',1 ]
    },
    method: "POST",
    header: {
        'content-type': 'application/x-www-form-urlencoded'
    },
    success: function (res) {
      
    }
})

请求的格式是下面这样的



正常浏览器是这样的

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…
  1. 包装参数
reqData = this._param(reqData);

其中 _param 就是 jquery的$.param方法 copy过来就好。

_param: function (a, traditional) {
        var class2type = {};
        var toString = class2type.toString;
        var hasOwn = class2type.hasOwnProperty;
 
        function toType(obj) {
            if (obj == null) {
                return obj + "";
            }
            // Support: Android <=2.3 only (functionish RegExp)
            return typeof obj === "object" || typeof obj === "function" ?
                class2type[toString.call(obj)] || "object" :
                typeof obj;
        }
 
        var isFunction = function isFunction(obj) {
            // Support: Chrome <=57, Firefox <=52
            // In some browsers, typeof returns "function" for HTML <object> elements
            // (i.e., `typeof document.createElement( "object" ) === "function"`).
            // We don't want to classify *any* DOM node as a function.
            return typeof obj === "function" && typeof obj.nodeType !== "number";
        };
 
        var
            rbracket = /\[\]$/,
            rCRLF = /\r?\n/g,
            rsubmitterTypes = /^(?:submit|button|image|reset|file)$/i,
            rsubmittable = /^(?:input|select|textarea|keygen)/i;
 
        function buildParams(prefix, obj, traditional, add) {
            var name;
 
            if (Array.isArray(obj)) {
 
                // Serialize array item.
                obj.forEach(function (v, i) {
                    if (traditional || rbracket.test(prefix)) {
 
                        // Treat each array item as a scalar.
                        add(prefix, v);
 
                    } else {
 
                        // Item is non-scalar (array or object), encode its numeric index.
                        buildParams(
                            prefix + "[" + ( typeof v === "object" && v != null ? i : "" ) + "]",
                            v,
                            traditional,
                            add
                        );
                    }
                });
 
            } else if (!traditional && toType(obj) === "object") {
 
                // Serialize object item.
                for (name in obj) {
                    buildParams(prefix + "[" + name + "]", obj[name], traditional, add);
                }
 
            } else {
 
                // Serialize scalar item.
                add(prefix, obj);
            }
        }
 
        // Serialize an array of form elements or a set of
        // key/values into a query string
        var param = function (a, traditional) {
            var prefix,
                s = [],
                add = function (key, valueOrFunction) {
 
                    // If value is a function, invoke it and use its return value
                    var value = isFunction(valueOrFunction) ?
                        valueOrFunction() :
                        valueOrFunction;
 
                    s[s.length] = encodeURIComponent(key) + "=" +
                        encodeURIComponent(value == null ? "" : value);
                };
 
            // If an array was passed in, assume that it is an array of form elements.
            if (Array.isArray(a)) {
 
                // Serialize the form elements
                a.forEach(function (item) {
                    add(item.name, item.value);
                });
 
            } else {
 
                // If traditional, encode the "old" way (the way 1.3.2 or older
                // did it), otherwise encode params recursively.
                for (prefix in a) {
                    buildParams(prefix, a[prefix], traditional, add);
                }
            }
 
            // Return the resulting serialization
            return s.join("&");
        };
        return param(a, traditional);
    },

偷个懒 直接copy粘贴过来 试试吧，我这边测试没有问题

把数组用 JSON.stringify转化成字符串吧
