Question

这是我调用函数的方式

        newPost({
            post: this.props.post,
            files: this.props.files,
        }, someOtherVariables)

函数：

newPost: async ({ post, files }, someOtherVariables) => {
    return upload(`/services/share/post/new`, post, files, someOtherVariables)
}

自从我升级到React Native 0.59.1以来，我一直收到“发布为只读”错误。尽管单击调试日志中的错误会将我重定向到该函数的声明，但是甚至没有调用该函数，并且通过在函数的第一行添加console.log（）comand对其进行了测试。 / p>

post并未声明为const，并且其内容甚至在函数或调用函数的行中都没有改变。为什么会出现此错误？

package.json：

"react": "16.8.0",
"react-native": "~0.59.1",
"@babel/cli": "^7.5.5",
"@babel/core": "^7.5.5",
"@babel/runtime": "^7.5.5",
"@babel/preset-env": "^7.5.5",
"babel-jest": "^24.9.0",
"babel-plugin-module-resolver": "^3.2.0",
"metro-react-native-babel-preset": "^0.56.0",
"jest": "^24.9.0",

我稍微缩短了代码以提高可读性。我将保留下面的整个代码，以防查看整个代码有帮助。

send() {
    if (this.fileSelected() && this.detailFilled() && this.groupSelected()) {
        this.setSending(true)
        let service = this.props.isUpdating ? PostService.updatePost : PostService.newPost
        service({
            post: this.props.post.type === 'CLOSE' ? { ...this.props.post, type: 'TEXT' } : this.props.post,
            files: this.props.files,
        }, progress => {
            this.setState({ progress })
        }).then(res => {
            this.setSending(false)
        }).catch(err => {
            console.log(err)
        })
    }
}



newPost: async ({ post, files }, onProgress) => {
    let formData = new FormData();
    onProgress(0);
    if (post.type === 'VIDEO') {
        post.video = await vimeoUpload(files[0], onProgress).catch(Promise.reject)
    } else {
        files.forEach(file => {
            file.name = encodeURIComponent(file.name)
            formData.append("files", file)
        })
    }
    formData.append("post", JSON.stringify(post))
    return upload(`/services/share/post/new`, formData, onProgress)
},

自从React版本升级以来销毁功能参数时出现“只读”错误
