Question

我在Android应用程序中进行注册时遇到问题。

static creaUtente(identity, FirstName, LastName, FiscalCode , Email) {
        let formdata = new FormData();
        formdata.append('Identity', identity);
        formdata.append('FirstName', FirstName);
        formdata.append('LastName', LastName);
        formdata.append('FiscalCode', FiscalCode);
        formdata.append('Email', Email);

        console.log(Configuration.base_url.rest + Configuration.apiRoutes.signUp)
        console.log(formdata)

        return new Promise((resolve, reject)=> {
            fetch(Configuration.base_url.rest + Configuration.apiRoutes.signUp,{
                method: 'POST',
                headers: {
                    'Content-Type': 'multipart/form-data',
                },
                body: formdata
            })
            .then((response) => response.json())
            .then((responseData) => {
                if(responseData.Error){
                    Alert.alert("Errore");
                }
                global.utente = responseData;
                resolve(responseData)
            })
            .catch((err) => {reject(err)})
        })
    }

这是我使用的代码，在获取中，我传递了指向我的API的链接（这可以正常工作。这是一个https链接）

但是当我尝试在我的应用程序中注册时，收到此错误：

例如，这是我收到的日志

[['身份'， {ProjectName：{用户名：'TNNFRZ77H01G273V'，密码：'12345'}}]， ['FirstName'，'Fabrizio']， ['LastName'，'Tonno']， ['FiscalCode'，'TNNFRZ77H01G273V']，['Email'，'Fabrizio.tonno@email.com']]} {[TypeError：网络请求失败]

我不知道该怎么办:( 你能帮助我吗？

在Chrome中使用调试器：
