Question

我正在设置可以进行价格检查的TF2交易机器人。定义布尔值是否以键定价时，我得到一个错误。

我尝试将isKeys替换为data [baseName] .prices [qualityId.toString（）]。Tradable [craftable [isCraftable.toString（）] [0] .currency ==“ keys” in if语句，但得到if语句中的右括号错误。

var data = {

};
var currencies = {

};
requestify.get('https://backpack.tf/api/IGetPrices/v4?raw=1&since=0&key=5cf17c256780725011449df2')
    .then(function(response) {

    data = response.getBody().response.items;
    console.log(data["Australium Tomislav"].prices["11"].Tradable.Craftable);
  }
);
requestify.get('https://backpack.tf/api/IGetCurrencies/v1?key=5cf17c256780725011449df2')
  .then(function(response) {

      currencies = response.getBody().response.currencies;
  }
);

function toRef(keys, high) {
    if (high) {
        if (currencies.keys.price.value_high != undefined){
        return currencies.keys.price.value_high * keys
        } else {
            return currencies.keys.price.value * keys
        }
    } else {
        return currencies.keys.price.value * keys
    }
}
function getPrice(item, high) {
    var name = item.market_name;
    var quality = item.tags[0].name;
    var baseName = name.replace(quality + " ", "");
    var qualityId = itemQualities[quality];
    var isCraftable = true;
    var isKeys = data[baseName].prices[qualityId.toString()].Tradable[craftable[isCraftable.toString()][0].currency == "keys"; // Error here
    for (i = 0;i < item.description.length;i++) {
        if (item.description[i].value == '( Not Usable in Crafting )') {
            isCraftable = false;
        }
    }

    if (high) {
        if (isKeys) {
            return toRef(data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value_high], true);
        } else {
            return data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value_high];
        }
    } else {
        if (isKeys) {   
            return toRef(data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value], false);
        } else {
            return data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value];
        }
    }

Answer 1

TL; DR ：您在错误的行上缺少]。并且在]行的下面还有多余的if(high){...}。

您在行中缺少方括号]， var isKeys = ...如其他答案所示。现在，我们不知道数据结构，

data[baseName]
    .prices[qualityId.toString()]
    .Tradable[craftable[isCraftable.toString()][0].currency*]*

或

data[baseName]
    .prices[qualityId.toString()]
    .Tradable[craftable[isCraftable.toString()][0]*]*.currency

但是，

您在行上有多余的方括号，

if (high) {
        if (isKeys) {
        /*--here>>*/return toRef(data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value_high, true);
        } else {
        /*--here>>*/return data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value_high;
        }
    } else {
        if (isKeys) {
        /*--here>>*/ return toRef(data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value, false);
        } else {
        /*--here>>*/return data[baseName].prices[qualityId.toString()].Tradable[isCraftable.toString()][0].value;
        }
    }

同样，我们不知道确切的数据结构。

Answer 2

您缺少可交易的方括号

([\D\s]+)(\d+)([\D\s]+)

Answer 3

在该行中缺少方括号（dX）。

您的行是：

#include <cmath>
#include <iostream>
#include <limits>
#include <type_traits> 

struct pos_inf {
    constexpr operator double() const { return std::numeric_limits<double>::infinity(); }
};

struct neg_inf {
    constexpr operator double() const { return -std::numeric_limits<double>::infinity(); }
};


template<typename dX, typename upper_bound = dX, typename lower_bound = dX>
class limit {
    dX dx;
    upper_bound lowerBound;
    lower_bound upperBound;
    double step_size;

public:
    limit(dX x, upper_bound lower, lower_bound upper, double step = 1) :
        dx{ x }, lowerBound{ lower }, upperBound{ upper }, step_size{ step }
    {}

    // with infinity these two will invoke operator double(), with actual double it will return the fixed value
    dX lower() const { return lowerBound; } 
    dX upper() const { return upperBound; }
    dX value() const { return dx; }
    double step() const { return step_size; }
};

int main() {

    limit<double, pos_inf, neg_inf> l(3.4, pos_inf(), neg_inf(), 2.2); // infinity
    limit<double> l2(3.4, 1, 5, 2.2); // fixed values
        std::cout << "value dx  = " << l.value() << '\n'
        << "lower lim = " << l.lower() << '\n'
        << "upper lim = " << l.upper() << '\n'
        << "step_size = " << l.step() << '\n';
    return EXIT_SUCCESS;
}

您在;(function($){ $(document).scroll(function(){ if ($(this).scrollTop() > 50) { $('.navbar').removeClass('navbar-dark'); $('.navbar').addClass('navbar-light'); $('.navbar').removeClass('bg-transparent'); $('.navbar').addClass('bg-white'); $('.site-title').addClass('text-dark'); $('.navbar .cta.btn-outline-success').addClass('text-dark'); $('.navbar').addClass('border-bottom'); } else { $('.navbar').removeClass('navbar-light'); $('.navbar').addClass('navbar-dark'); $('.navbar').removeClass('bg-white'); $('.navbar').addClass('bg-transparent'); $('.site-title').removeClass('text-dark'); $('.navbar .cta.btn-outline-success').removeClass('text-dark'); $('.navbar').removeClass('border-bottom'); } }); })(jQuery);处打开了一个方括号，但直到该行末尾才将其关闭。编译器期望一个]，但是找到一个var isKeys = data[baseName].prices[qualityId.toString()].Tradable[craftable[isCraftable.toString()][0].currency == "keys"; // Error here。

我不熟悉您使用的API，但我想以下可以解决该错误：
