如何在JSON fetch API中传递两个类数组结构

Question

这是来自react原生文档的示例代码。

fetch('https://mywebsite.com/endpoint/', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    firstParam: 'yourValue',
    secondParam: 'yourOtherValue',
  })
})

现在我想将两个类似数组的结构或数据发布到url，这些参数如下所示：

fetch('https://mywebsite.com/endpoint/', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    0: "{"fromCity":"Mumbai, IN - Chhatrapati Shivaji International (BOM)","toCity":"Goa, IN - Dabolim (GOI)","depart":"09-04-2017","returndate":"","adult":1,"child":0,"infant":0,"classoftravel":"E","prefferedairline":"AI","trip":"dom","tripType":"one way"}",
    1: "[{"selectedOnwardFlight":[{"lstExtraServices":[],"flightDuration":"01:15","departuretime":"09-04-2017T13:30:00","arrivalairport":"GOI_Dabolim, Goa","freeBaggageAllowedWeight":25,"segment":1,"departureairport":"BOM_Chhatrapati Shivaji International, Mumbai","mac":"AI_Air India","fno":"663","dpartTerInfo":"2","oac":"AI","arrivaltime":"09-04-2017T14:45:00"}],"selectedReturnFlight":[],"selectedThirdFlight":[],"selectedFourthFlight":[],"selectedFifthFlight":[],"airlineLogoPath":"AI.png","airlineName":"Air India","airlineRecommend":"N","airlinecode":"AI","faretype":"Refundable","flightsID":"0","nonStop":"Y","onduration":[["0:1:15"],["NA"],["0:1:15"],["NA"],"Chhatrapati Shivaji International, Mumbai",0],"reduration":[],"thirdduration":[],"fourthduration":[],"fifthduration":[],"fare":[{"lstExtraServices":[],"ibp":"0","cbp":"0","tp":"6528","pc":"AI","fareBasisDetails":[{"paxType":"ADULT","fareBasisCode":"TAP15B","segment":"1-663","fareType":"Refundable","rbd":"T","breakPoint":"Y"}],"fareClassType":"Economy","taxDetails":{"itaxdetails":[],"ctaxdetails":[],"atax":"496","ctax":"0","ttax":"496","itax":"0","ataxdetails":[{"name":"YR","value":"70"},{"name":"IN","value":"0"},{"name":"WO","value":"150"},{"name":"YM","value":"138"},{"name":"JN","value":"128"},{"name":"xt","value":"10"}]},"abp":"2200"}],"vendor":"amadeus","totalprice":"2713","originaltp":"2696","serviceTax":17}]",
  })
})

但是这是不起作用的，如何在post fetch method.While attaching.Please中发布两件事注意那0:和1:描述两个独立的json值的事情

Answer 1

问题是你的JSON是无效的--像0这样的属性应该加引号，例如JSON.stringify({"0"：...，然后你在对象标识符的开头加上一个引号{0："{"fromCity“... --> this应该是{"0"：{"fromCity”...

以下是正确设置邮件第一部分格式的示例：

{ "0"：{"fromCity "：“孟买，IN - Chhatrapati Shivaji国际(印度) "，"toCity "：”果阿，IN -达博林“，"depart "："09 - 04 - 2017”，

和属性1的开始：

"1"：[{"selectedOnwardFlight ":[{"lstExtraServices ":[]

等
