使用带有 SOAP Web 服务的 javascript fetch API

Question

我在使用 fetch API POST 到 SOAP Web 服务时遇到了非常困难的情况。我使用 chrome 插件解决了我的 CORS 问题，但现在我发送的格式似乎存在问题。我已经尝试实施我在其他问题中看到的修复程序，尤其是在 Content-Type 和诸如此类的问题中，但我无法得到任何不同的结果。它只是简单地不喜欢插槽 1 中的

基于其他问题，我发送的实际“数据”看起来确实与其他 SOAP 请求有点不同......他们提到了一个信封，他们定义了一个 XML 版本等。我的是我发送的纯 XML 数据在本地的 SOAP 服务测试器中。所以我想我不知道的是该软件是否在将请求“有效负载”发送到服务之前添加了额外的细节。

WSDL 不是很有帮助，但我可能找错地方了。

非常感谢任何建议。

我的 Javascript/获取：

var base64 = require('base-64');

let url = 'http://SCRB4APUSLSA801:9080/apex/services/argobasicservice';
let username = 'abo055';
let password = 'hidden';
let headers = new Headers();

export const N4RecordScan = {

    submit(data) {

        headers.append('Content-Type', 'text/xml');
        headers.append('SOAPAction', 'basicInvoke');
        headers.append('Authorization', 'Basic ' + base64.encode(username + ":" + password));

        let dataPrefix = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:arg="http://www.navis.com/services/argobasicservice"><soapenv:Header/><soapenv:Body><arg:basicInvoke><arg:scopeCoordinateIds>APMT/USLAX/LAX/LAX</arg:scopeCoordinateIds><arg:xmlDoc><![CDATA[';
        let dataSuffix = ']]></arg:xmlDoc></arg:basicInvoke></soapenv:Body></soapenv:Envelope>';

        data = dataPrefix + data + dataSuffix;

        console.log('about to send ' + data);

        fetch(url, {
            body: data,
            method: 'POST',
            mode: 'cors',
            headers: headers,
            credentials: 'include'
        })
            .then(response => console.log(response))
            .catch(function(error) {
                console.log(error);
            });
        //.done();

    }
};

这是我发送的数据：

<gate><record-scan><gate-id>USLAX</gate-id><stage-id>asd</stage-id><lane-id>asd</lane-id><external-console-id>asd</external-console-id><truck tag-id="asd" license-nbr="asd"/><equipment><container eqid="asd" on-chassis-id="asd" /><chassis eqid="asd"></chassis></equipment></record-scan></gate>

这是我得到的回复：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>

<detail>…</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

这是我要联系的服务的 WSDL。

Answer 1

您为每个请求重复使用相同的 Headers 对象。这意味着您每次执行新请求时都会添加新的 Authorization 标头。

将let headers = new Headers(); 移动到函数体中（并使用const），以使其工作！
