调用接口alipay.open.agent.facetoface.sign报错source.on is not a function

[zhangyj1998]

接口文档地址https://opendocs.alipay.com/isv/04ejak?pathHash=20d91b56 因为里面需要传图片，所以采用form的形式上传，其中shop_address字段为object，就是因为这个字段，导致报错，请问如何解决

@troyeagle 看看，应该是 bug

[zhangyj1998]

我尝试将node_modules/alipay-sdk/lib/form.js修改之后就可以了，但是不确定对其他接口是否有影响

addField(fieldName, fieldValue) { if (isJSON(fieldValue)) { // 当 fieldValue 为 json 字符串时，解析出 json // this.fields.push({ name: fieldName, value: JSON.parse(fieldValue) }); this.fields.push({ name: fieldName, value:fieldValue }); } else { this.fields.push({ name: fieldName, value: fieldValue }); } }

应该和 #93 是同一个问题，底层确实没针对 object 类型的字段做序列化，应当都要 stringify 。即刻修复

[troyeagle]

fixed on v3.3.1
