Question

在我的浏览器中加载此链接，该链接由USPS提供的用户ID和有关包的详细信息

Link: http://production.shippingapis.com/ShippingAPITest.dll?API=RateV4&XML=<RateV4Request USERID="[userid]"><Revision/><Package ID="1ST"><Service>PRIORITY</Service><ZipOrigination>02211</ZipOrigination><ZipDestination>90210</ZipDestination><Pounds>5</Pounds><Ounces>2</Ounces><Container>RECTANGULAR</Container><Size>LARGE</Size><Width>15</Width><Length>30</Length><Height>15</Height><Girth>55</Girth></Package></RateV4Request>

我返回的结果正确（下方）

<RateV4Response>
  <Package ID="1ST">
    <ZipOrigination>02211</ZipOrigination>
    <ZipDestination>90210</ZipDestination>
    <Pounds>5</Pounds>
    <Ounces>2</Ounces>
    <Container>RECTANGULAR</Container>
    <Size>LARGE</Size>
    <Width>15</Width>
    <Length>30</Length>
    <Height>15</Height>
    <Zone>8</Zone>
    <Postage CLASSID="1">
      <MailService>Priority Mail 2-Day&lt;sup&gt;&#8482;&lt;/sup&gt;</MailService>
      <Rate>86.65</Rate>
    </Postage>
  </Package>
</RateV4Response>

但是，尝试使用以下代码块从Google Apps脚本编辑器中的函数加载API时：

function xmlLoader(){
  var pounds = 5;
  var ounces = 2;
  var userid = "[userid]";
  var url = "http://production.shippingapis.com/ShippingAPI.dll";
  var options =
    {
      "API" : "RateV4",
      "XML" : "<RateV4Request USERID=\"" + userid + "\"> \
                 <Revision/> \
                 <Package ID=\"1ST\"> \
                   <Service>PRIORITY</Service> \
                   <ZipOrigination>02211</ZipOrigination> \
                   <ZipDestination>90210</ZipDestination> \
                   <Pounds>" + pounds + "</Pounds> \
                   <Ounces>" + ounces + "</Ounces> \
                   <Container>RECTANGULAR</Container> \
                   <Size>LARGE</Size> \
                   <Width>15</Width> \
                   <Length>30</Length> \
                   <Height>15</Height> \
                   <Girth>55</Girth> \
                 </Package> \
               </RateV4Request>"
    };

  var response = UrlFetchApp.fetch(url, options);
  Logger.log(response.getContentText());
};

这是我带来的错误，

<?xml version="1.0" encoding="UTF-8"?>
  <Error>
    <Number>80040B19</Number>
    <Description>XML Syntax Error: Please check the XML request to see if it can be parsed.</Description>
    <Source>USPSCOM::DoAuth</Source>
  </Error>

非常感谢任何帮助

我没有任何usps ID，所以我无法进行全面测试，但对我来说问题来自你给出的URLFetch参数。试试这段代码：

function xmlLoader(){
  var pounds = 5;
  var ounces = 2;
  var userid = "1000"; //"[userid]";
  var url = "http://production.shippingapis.com/ShippingAPI.dll";
  var payload =
    {
      "API" : "RateV4",
      "XML" : "<RateV4Request USERID=\"" + userid + "\"> \
                 <Revision/> \
                 <Package ID=\"1ST\"> \
                   <Service>PRIORITY</Service> \
                   <ZipOrigination>02211</ZipOrigination> \
                   <ZipDestination>90210</ZipDestination> \
                   <Pounds>" + pounds + "</Pounds> \
                   <Ounces>" + ounces + "</Ounces> \
                   <Container>RECTANGULAR</Container> \
                   <Size>LARGE</Size> \
                   <Width>15</Width> \
                   <Length>30</Length> \
                   <Height>15</Height> \
                   <Girth>55</Girth> \
                 </Package> \
               </RateV4Request>"
    };

  var options={
    method:"POST",
    payload:payload
  }

  var response = UrlFetchApp.fetch(url, options);
  Logger.log(response.getContentText());
};

另请注意，USPS和UPS都没有最好的XML解释器。我发现这篇文章正在搜索解析公司名称中＆符号的HTML实体的语法问题。（应该在XML中支持，但显然它会导致USPS呕吐）他们中的一些人对“订单”也非常挑剔。如同未完全按照文档指定的那样，元素顺序将导致错误。我也遇到了他们声称的字段上的问题＆＃39;是可选的，但不是 - 我需要发送一个空的＆＃39;标签 - 和其他人在空标签上呕吐。我昨天遇到的另一件事，验证地址api似乎想要翻转address1和address2，但仅限于输出。（在输入时如果你只发送地址2就会呕吐。）

如何使用Google Apps脚本通过USPS API获取国内运费？
