我想在我的应用上添加firebase通知.我在YouTube上关注了一个视频(https://www.youtube.com/watch?v=xx7hemn3FY4)但是当我在我的flutter项目中执行相同的操作时出现错误:库com.google.android.gms:play - [[15.0.1,15.0.1]]的各种其他图书馆正在要求服务地下室,但结算为11.8.0.禁用插件并使用./gradlew:app:dependencies检查依赖关系树.

我在评论中看到了几件事.

项目gradle:

 buildscript {
    repositories {
        google()
        jcenter()
    }

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'

    classpath 'com.google.gms:google-services:4.0.1'
    //classpath 'com.google.gms:google-services:4.0.0'

}
}

allprojects {
    repositories {
        google()
        jcenter()
        /*
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
        */
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion …

我想将我的应用程序与 Microsoft Graph 连接。我在 Azure 中创建了我的网络应用程序（我有我的client_id和client_secret）。我可以发送请求以获取授权码https://login.microsoftonline.com/common/oauth2/v2.0/authorize。

问题是，当我使用 Postman（带选项）发送请求POST以获取访问令牌https://login.microsoftonline.com/common/oauth2/v2.0/token（正如 “使用权限”部分中所述form-data）时，我收到“AADSTS9000410：格式错误的 JSON”错误：

{
  "error": "invalid_request",
  "error_description": "AADSTS9000410: Malformed JSON.\r\nTrace ID: f5c1dd4b-ad43-4265-91cb-1b7392360301\r\nCorrelation ID: 1dea54ed-bb43-4951-bc9e-001877fe427b\r\nTimestamp: 2019-01-14 21:38:42Z",

  "correlation_id": "1dea54ed-bb43-4951-bc9e-001878fe427b"
}

此外，当我在 Postman 中使用原始选项发送相同的请求时，我收到“AADSTS900144：请求正文必须包含以下参数：'grant_type'”：

 {
  "error": "invalid_request",
  "error_description": "AADSTS900144: The request body must contain the following parameter: 'grant_type'.\r\nTrace ID:a7c2f8f4-1510-42e6-b15e-b0df0865ff00\r\nCorrelation ID:e863cfa9-0bce-473c-bdf6-e48cfe2356e4\r\nTimestamp: 2019-01-1421:51:29Z",
  "error_codes": [900144],
  "timestamp": "2019-01-14 21:51:29Z",
  "trace_id": "a7c2f8f4-1510-42e6-b15e-b0df0865ff10",
  "correlation_id": "e863cfa9-0bce-473c-bdf6-e48cfe2356e3"
}

但是，当我application/json在 Postman …
